I thought it would be good to write this up, because I found a lot of bad information about this particular add-on (at least as concerns 2nd gens), and it might help others to set it straight.

Don't fear the wall-o-text. This writeup is long because it's detailed, and thus hopefully of more value to somebody. The hardest part of the job is getting all the pieces, which I hope I've made simple. It probably won't take longer put all this stuff on the car than it does to read the write-up a few times. It's a really easy and worthwhile upgrade.

PARTS

As you will find elsewhere via the google, to add 100% factory cruise control to a non-cruise car such as the Brighton, you need only buy the parts and plug them in, and these are the parts you need to source:

interior
dash Cruise button
steering wheel Set/Resume/Cancel switch, or entire steering wheel with the switch on it (easier, but you will need to go rent a steering wheel puller)
brake pedal switch, four-pin type
clutch pedal switch, if a 5-speed car.
cruise computer & two mounting nuts

under hood
cruise (throttle) actuator & bolts
cruise air pump, bracket & bolts
the two vacuum hoses and hard line connecting these two

Unlike some cars, on the Legacy the vacuum-operated cruise actuator has nothing to do with the vacuum lines on the engine. Instead there is an electric pump dedicated to the cruise control system. Instinctively, I like this setup; the Legacy's cruise control works very well, and this is probably why.

Instead of screwing with modding my steering wheel, I replaced it. Actually I just wanted a leather wrapped steering wheel anyway. I got one on ebay for like 85 bucks in great shape, out of a '99 GT. If you can spend a few more dollars and do that, it's worth it. Yes, my driver's airbag swapped over just fine; they are exactly the same.

PARTS (cont.)

All items under interior except the cruise computer can be gotten out of any 1995-99 Legacy, any year, manual or auto, they are all the same. Just to get that out of the way.

cruise computer
On '95s, the computer is in the passenger side kick panel, while in all later cars it's under the dash.

part numbers (build date):
xx-9/95.....................87022AC010
10/95-5/97................87022AC050
6/97-5/98..................87022AC051
6/98-xx (except L)......87022AC051
6/98-xx (L)................87022AC070

I do not know if the 96-99 interchange at all but would highly recommend getting the right one for your year; however, there is no difference between auto and manual cars, at least for 2nd gen, contrary to what you may find via the google. So if you have a manual car and you find the right year car in auto, as it probably will be, snag everything and just buy a clutch switch from the dealer -- it cost me around $18. (in case you were wondering, you can't do without a clutch switch on a 5-speed car; the system simply won't engage unless that switch is plugged in and depressed)

actuator
This is the thing that mounts to the firewall on the driver's side and has a cable to pull the throttle, connecting up right next to the actual throttle cable.

1995-98....................87011AC012
1999 (exc. L).............87011AC012
1999 (L)....................87011AC050

There are at least, but probably only, two incompatible versions of this. Seemingly, the '99L part is too short to work on the older and 2.2L cars. I got one marked 87011AC010 from a '95 and that worked for me.

pump
From the actuator, look where the vacuum hose goes from that to a hard line clipped onto the firewall. You need that hard line, and you need the pump that's on the other end, on the passenger side of the engine bay. You also need its entire bracket. One end mounts below, the other mounts behind a canister that's part of the a/c system (the dehydrator). The pump I got off a '99L fits and works great on my '96 Brighton, so I am prepared to say it doesn't matter.

INSTALLATION

...is really simple, actually.

under hood
The cruise actuator bolts to the firewall on the driver's side, you should know already if you pulled it from a junkyard car. The bolt holes will be plugged up with rubber plugs unless someone removed them or they rotted out. Run the actuator cable alongside the throttle cable, slip the end into the throttle pulley, and mount it up on the bracket beside the throttle cable. Adjust so there is no slack but the throttle can close all the way. While you're at it check the throttle cable and adjust it too if needed. If the throttle cable seems much too long or too short, you bought the wrong part. Go buy the right one.

The air pump on its bracket mounts on the other side. I said the '99L part fits and works on my car, and it does, but I think the bolt holes aren't exactly the same. I was still able to get it bolted on at three points (two high, one low) with a little fiddling and pushing. No big deal.

Your vacuum hard line clips into the highest slot on the firewall. You need the vacuum hoses connected at each end. Duh. Also, there is an electrical connector buried in the wiring harness right near the cruise pump. Dig it out and plug it into the pump. You're done under the hood.

interior
Go look at the brake pedal. There is a switch that the brake pedal pushes when nothing is pressing on the pedal. Take that switch out, disconnect it, install the 4-pin switch and connect it to the 4-pin connector bundled with the 2-pin brake switch connector. If installing a clutch switch, it goes in the same position but on the clutch. Do the same thing. Find a 2-pin plug (mine was a sky-blue color) and plug it in. Make sure the little plastic plug on the clutch pedal is intact. Otherwise there is nothing to push the switch. You might want to replace both of these with a short bolt and lock nut, or something. That way, they will never wear out.

Dash switch goes in the dash. It's next to the rear defroster button on the right side of the cluster surround. The cluster surround comes off easily, two screws high and two screws low. Remove the blank plate, plug in the button and pop it into the surround.

As I mentioned, I replaced the whole steering wheel. You can keep your wheel but you'll have to take it apart a bit and dremel out the side. I wanted leather so I just changed wheels. Even if you don't want leather it's probably easier to put a new wheel on. Either way...

First, pull the horn fuse under the dash. If you don't, you'll find out why I told you to on the next step.

Next you will take the airbag loose. This honestly isn't that big a deal, just don't be stupid. Don't put your face in front of the airbag, and don't be careless with it. Don't drop it or rub your hands on a wool sweater and try to shock the connector. Handle it gently and place it metal side down, plastic side up. Be warned, an airbag going off can injure you. If you aren't an idiot, though, it's probably not going to go off on you.

Undo the two Torx screws visible from the left and right side of the steering wheel, behind the 9 and 3 o'clock hand positions. The airbag can jiggle out at this point. Carefully undo the yellow connector. It has a clip, and it's very tight. I needed a small flathead screwdriver to pry it apart. Remove the airbag. Again, handle carefully and don't be stupid. Set the airbag aside, placing it metal side down, plastic side up.

If you want to hack up your steering wheel to install the switch, do so at this time. There may be a ground screw or something you need to deal with. If you're simply replacing the wheel, do what you need to to get the wheel dead straight and centered, break loose and remove the big nut at the center, then install the puller: two bolts thread in on either side, center bolt and the little metal collar (important! or you will damage the threads on the steering column), tighten that sucker down till the wheel pops off. Push new wheel on by hand in the same position as the old one, install nut, torque to spec or just hit it briefly with a cordless impact. Put the airbag back in. After you reattach the yellow connectors on the back of the airbag, look on one side for a green button and press it in till it clicks. Before tightening the Torx screws you may want to switch the ignition on and make sure the airbag light goes off after a moment (and the bag doesn't blow up, lol. kidding. partly.)

Finally, mount the cruise computer up under the dash, if that's where it goes. The under-dash location is approximately behind where the diagnostic connector is located on the lower dash panel. There are three bolts up there, the computer hangs from two of them. You might need to take something else loose first, just put it back afterward. The plug for the computer will be right nearby.

AND THEN
Fire up the car, press the cruise button on the dash, see it light up. Go test drive it. It should work. If it doesn't, make sure all the connectors are plugged in and your two vacuum hoses under the hood are connected. If it still doesn't work then you have the same course of action as an L/GT owner, start troubleshooting from the FSM (Odds are you got a bad used part.)

Very well written. I'm sure this will be incredibly useful for some of the 2nd generation owners. Did you happen to take any pictures? Not to be nitpicky, but people love pictures. Otherwise, great write up.

I didn't add pictures cause, really, none of this stuff is the least bit tricky to locate. Especially if you are pulling the setup off a junkyard car, which is the easiest route to go, you will know where to put everything back.

But, I will say that a leather wheel is the way to go

this is SO awesome. when i was in my car i noticed a plug going to the cruise control blank, and got me thinking about plug and play cruise. just searched and found this thread. super stoked. i went to the yard once today, but i am now going back to find all of the parts. i will report back with my results. hoping most of the parts will bolt on to my RHD car just the same as a standard LHD.

my summer road trips just became possibly more enjoyable.

cant for the life of me find the module connector under the dash. i see the two studs coming down to mount the module but i cant see the connector... ANYWHERE. frustrating finding anything for my rhd. the vacuum pump bolts up on the left side, eliminating the need for the long steel pipe running to the cable actuator. the plug for the vacuum pump is there, the steering wheel plug has the necessary plug for the steering wheel switch, the dash has the correct plug for the cruise switch. just can't find the plug for the module.

was the plug loose or taped to another harness at all? im trying to look up the connectors for the different modules to see if there is one different from what i got. (051)

Nice write up. I would like to suggest that any time you mess with the steering wheel / airbag assembly, it might not be a bad idea to first disconnect the positive (+) battery terminal. Just as a precaution.

On the 1995 RHD postal legacy all of the wiring was there for this mod. except the plug for the vacuum pump under the hood was on the LH side below the cable actuator I used the LHD pump and bracket and bolted it where the AC line bracket mounted on the RHD car.

Also the plug for the cruise control computer was in the LH door pillar tucked up under the dash board.

Works perfect I got all of my parts from a 1995 LHD junker

now using cruise control RHD style

willbhere4u THANK YOU!!! you were here for me, nearly 2 years later!!! I am installing a remote start and figured I would look around for the plug. My dad was interested in helping me find the plug, so I pulled up this post to see if there was a picture of it for him. Instead you lead me right to the plug, Thanks man!!
