Question Clutch Safety Switch Disable

I have been searching for the last half-hour and I can't find a link on how to disable the clutch safety switch on a MY02 WRX. I did read through some old posts about earlier model imprezas...they say you have to cut the wire behind the clutch pedal and connect it to another wire for a constant circuit.

Is it the same for a 2002 WRX?
Where/what wire(s) must I disconnect and/or connect to allow me to start the car without pushing the clutch pedal in?

Does anyone who's done this have pics of what they did?

Thanks, and if this has been discussed on this site, please point me to the correct link.

Thank you.

Go down to your clutch pedal and look for the safety switch. Most switches will close the circuit when the clutch is depressed, check this with a meter. Once you verify, then disconnect the connector and make a jumper. Done. Here is the only thing though, I don't know about your car, but some cars use 1 safety switch for the cruise control and starter interlock, so if you mod the switch this way, your cruise control may not work afterwards. So if this is the case, you will need to use a relay to disable the safety only when the starter is being cranked.

^^thanks for the info.

I'll have to wait to get home so I can check for that clutch safety switch.

I think my car has 2 wires, one for cruise and one for the safety switch...although I'm not sure.

If that's the case, I'll post a pic and see if anyone can let me know which wires to cut.

All the switches should have 2 wires, one is a ground reference usually and the other is the return signal. You need to find out if you have 2 switches. Look under there and hold down one at a time to see which one starts the car.

the cruise switch moves as soon as you move the clutch, whereas the other one (motor start switch) moves only when the clutch is near the bottom.

^^I tried moving in the pedal, but I couldn't exactly see any switches moving...I think it's because there's so little space to see anything under there without rotating my neck 270. Anyway, here's a pic I took:



I'm assuming the white switch is the correct one to unplug? Also, the wires look like they have been taped back together....is this normal, or has the previous owner tried the same thing I want to try?

is this as simple as unplugging one of the connectors or do I have to splice and dice?

if there's 2 switches if i can remember......just unplug 1 of them and make a jumper (piece of wire stuck into each hole on the connector) try to start it, if it does, that may be the one....you could go drive and see how your cruise responds if hitting the clutch turns it off then that should be the right one.
i think. i was going to do that when i installed a rem. start but did it another way instead.

p.s. those plugs are kinda hard to unplug, i had to use small pliers and a screwdriver

heh, same with the DSM guys...

Anyway, I'm going to try skateboy's method to unplug the connector (which seems to be a task by itself) and hopefully I won't screw anything up.

Default top one with white plug is starter interlock

Per service manual of '04.

To bypass the switch I would guess simply connecting YlwGrn & Blk wires.

Let us know.

Cheers.

Yep, this did the trick.

I took a blade and shaved off some insulation on both wires (about 1/8in.)
Rather than use the "Vampire clips" as GLwagon suggested, I was able to connect the two wires by simply wrapping some copper wire around the exposed portions of each wire. Then I taped it off securely with some electrical tape, and everything seems to be working fine.

Thanks to everyone that helped me out
