Default Need help!! Need to find a +12v switched wire NOW! Please help!

Hey everyone,
I'm at my wits end here....
I'm installing some gauges and I've had problems since i got them.
I sent the control module back and found out that the wiring harness was wired wrong...
Okay, fixed that...

Now I just need to find a +12v switched wire to tap into.
I'm frustrated because I tried the radio wire... no luck...
I tried the wire on the Hazard light harness... no luck...

Each time I tapped into the wires listed above, the gauges would remain on even after I took the key out, and would get "stuck" in a looping shutdown sequence.

Can someone PLEASE help me find a true +12v switched wire that turns off when the ignition is off, and isn't interupted by the cranking of the engine???

I really want to get these working! And I'm so close now it's so irritating.

There is also the +12v on the clock harness, and it's labeled for you! That's what I used for my Defi Controller and NO problems whatsoever.

I just went through the same thing last night. The +12V switched wire that stays on when the engine cranks is pin #6 in the hazard light switch. It's dark green with black stripe. you should use a DMM to verify that first though.

Thanks guys!
I found my old DMM and will have to try it out when I get back from a little trip I'm taking this weekend.
I will try the hazard light harness first since that's where the wire is resting now. If not I'll DEFINITELY be using the clock harness, especially if it's labeled already!

The weird thing about the hazard light location was that I thought I tapped into that green cable, and the gauges would only activate if I pressed the hazard light switch... maybe I just tapped the wrong green cable??

Anyway, I'll let you all know if I got it or not when I get back.

Thanks again!

You may have tapped into the "light green/black stripe" cable. That's not the right one. The correct one is dark green/black stripe and is the second pin from the left on the bottom row. pin #6.

remember one thing, don't tap into a wire until you have made sure it's the correct one with a voltmeter.

I'd just go to the clock housing (yellow w/blue stripe) - in addition to making sure that you are tapping the right wire, I always recommend tapping the wire to something as non-critical as possible - the clock harness is just a good, safe place to tap.

well i just got back from a trip and I'm still struggling...
My gauges are tapped into the Batt & Acc wire on the back of the clock's wiring harness.

Now my gauges are now stuck on even when the car is off and the keys are removed.

The boost gauge that I have connected DOES work though, but it just won't turn off when the car is turned off...

I'm so frustrated...
What am I still doing wrong? I thought this was it!!

Okay, this is for 2002 Subaru WRX drivers that might read this thread for advice:

If you tap into the hazard switch harness you will want to tap the LIGHT GREEN W/ WHITE STRIPE wire for switched +12V that stays on during cranking but turns off with the ignition.

I have verified this with a DMM and my gauges are working now!

Tap directly off of your fuses that are down and to the left of your steering wheel. Take off the little coin holder and you will see them. Then look in the back of your owners manual and find the fuses section. You can buy fuse taps at radio shack i think and use the correct fuse to meet your needs. ie, To power my gauges I used the ignition fuse so when I turn my car on the fuses do.

This took a lot of the hassle out of trying to find a specific wire.

Yeah that works too if you want to spend a little extra cash. Either way works fine, the main thing I'm happy about is that I got mine working finally.
