Default DRL High Beams

Yeah I know theres other forums similar to this but this one is about independent high beams, I am wondering if it got the same idea of the independent fogs where you just pull the relay out and bend one of the leg and add it to the add-a-circuit.

I am wondering if one of those relay in the fuse box area is for the high beams and would it have a similar idea of doing it.

I converted my highbeams to work as the DRL's.

This conversion is for non-HID headlamp systems. I will look into what would need to be done if you want to convert an STI w/OEM HID's so that the same can be done (using the high-beams as DRL's).

It's a matter of swapping two wires from the highbeam relay with two wires from the lowbeam relay. Both relays are located behind the lower right-hand side of the glovebox. One relay is colored black and the other is colored blue.

You want to swap the following terminals:
#1 of the HB relay with #1 of the LB relay
#4 of the HB relay with #5 of the LB relay

I also installed a 2008 DRL resistor to drop the output to 50% instead of 85% so I don't blind oncoming drivers. This is your choice.

NOTE: You may not have to cut any wires to perform this modification. I say 'may' because two of the wires may or may not reach the other relay when performing this swap.

If you do not want to cut any wire, you can make a pair of extensions. You would need two male-blade terminals that you can get from say Radio Shack, two lengths of 16-gauge wire about 2" long and the other two terminals you can source from Hella. Why? The ones that are fitted into the connector have special locking tabs on them.

The part-number for the Hella terminal (same for either) is: HL87272 (6.3mm (1/4") Receptacle) and you can get them from Susquehanna Motorsports: http://www.rallylights.com/detail.aspx?ID=436

High-beam relay:

X 1 X
2 X 3
X 4 X

1 = Red
4 = Red w/green stripe

Low-beam relay:

X 1 X
2 3 4
X 5 X

1 = Yellow w/red stripe
5 = Black

I checked and the above is true for 2004 and 2006. Presumptively, the same is true for 2002, 2003, 2005, and 2007.

Well I would like to be able to control if I want the Highbeams to be on, I would like to create a switch or something next to the fog switch and then be able to make the highbeams go on itself by pressing the switch.

just to let everyone know, i did this today and it worked beautifully. a couple tips, since there are two yellow/red wires going to the black low beam relay, and the relay itself isn't labeled with numbers, the #1 yellow/red wire that you want to switch into the high beam relay is the top one, not the centre one. also getting a 2008 drl resistor is highly recommended, i haven't gotten mine yet, but those drl's are bright when they're pumping out 85%. i'll be driving with my hid low beams on until monday when i can pick up the new resistor to save fellow motorists some blindness.

other than that, everything works like stock, except the drl's come out of the high beam bulbs instead of low beam projectors.
lights off, e-brake up = no lights
lights off, e-brake down = drl's
lights 1 click = drl's, corner lights, tail lights (and fogs via switch, i did the foglight mod)
lights 2 clicks = low beams, no drl's, corner lights, tail lights (fogs via switch)
and high beams work fine both pulling the stick to flash and pushing for constant.

thanks big E for figuring this out, saved me a whole bunch of time with wiring diagrams, i really hate trying to figure out wiring.

can't wait to get my 50% resistor

Blame, you are welcome. FYI: fill-out your profile so if you need help in the future we'll know what you drive and so-on.

*******

With respect to the 2008+ DRL resistor I recommend the following:

The original resistor can be removed from the mounting bracket. Remove the bracket with the resistor attached and service the assembly out of the car - this will make working on it much, much easier. The new resistor can be mounted to the existing bracket but, you will need to modify it so the new one will fit.

The new resistor is slightly physically bigger so it will be closer to vacuum hoses and wires. Get hi-temperature wire-loom and cover any hoses and wires, essentially shielding it from the heat that is given off while its in use. Also tie back any hoses and wires using zip-ties.

I have not yet taken any pictures of the car, but expect to do so soon.

Happy Motoring!

^^^ but i was wondering about if the headlight relays where in the same spot on a 04 wrx and if one of the relays were still blue in color and if the wires that i have to interchange where in the same location

as far as the wiring on my 06, yes the #5 wire in the low beam relay is a black ground wire, it is intersected by the ground from the drl resistor according to my wiring diagrams

subscribed. Just did a TSX retro, and dont like the idea of no drls. I pulled the connector, and like this solution better. Anyone have a part number on the 2008 resistor?
I am going to look for some pics of these two relays to make sure I know what I am doing. Big-E, can you post pics of the relays?

thx- i think I found them, but I am curious how you actually accomplished the wire swap - did you pull the wires out of the connectors? or just cut and solder? The part number on the resistor would be wicked too.

I will PM you one internetz. thx

Sorry, no pics yet - I've been very busy. I hope to take some this week.

*******

OEM DRL resistor @ 50% output (under hood): 84057FG000

With the turbo models, you will have to get wireloom both in 1/2" and 1" or thereabouts to effectively cover the turbo boost controller hoses and wires. These items are effectively located over the DRL resistor and it puts out a lot of heat. By covering things with the wireloom, you can add protection to these items from the heat.

You will also have to remove the OEM DRL resistor while it's attached to the mounting bracket. You will have to modify the bracket and/or the new bracket for the new resistor to have it attach to the original mounting bracket.

*******

No cutting or soldering. I used crimp connectors, some wire and electrical tape.

From the LH relay, you can release the two wire terminals from the connector and plug them into the RH connector.

You cannot plug the two wire terminals from the RH relay into the LH connector because they are too short. A solution is to make two 'extensions'.

For the extensions, you will need two 3" lengths of 16-18GA wire. For the ends that will plug into the existing wire terminals, you can use shielded crimp-on connectors from Radio Shack. For the terminals that will plug into the connector, you will need to get Hella crimp-on self-locking terminals PN: HL87272

http://www.rallylights.com/detail.aspx?ID=436

You will also need electrical tape and I recommend 3m brand of electrical tape that Radio Shack also sells. It has the best hold and has a wide temperature range for useage, meaning it can get real cold outside and it won't shrink and the glue won't fail, for example.

wow. Thanks. That should be enough to go by. I am surprised that that resistor is going to run almost 75 bucks. I wonder if there is something else that might work?

Chaplin's Subaru Genuine Parts sells it for just under $50. https://www.chaplinssubarugenuinepar...parts_cat.html

Put the PN into their "search by part number or keyword" and you'll see both the list price and the over-the-counter price.

Thanks, thats the only place I get OEM parts. My point was that I have to pay extra shipping and duties to get them to Canada, but I guess I didnt type that. I am going to try it without first, and see how bad it is.

I havnt bothered to try yet. I wired my fog lights so that I can turn them on whenever there is IGN power, so I have been using them as DRLs. I am torn on whether to just keep it like this and sell my fog covers, or go the high DRL route.
