So I have my defi gauges mounted and everything ready to go. Problem is, I have major suck when it comes to wiring. The defi control unit has 4 leads; +power, ignition, ground and illumination.
I plan on mounting the control unit where the ashtray is so I can use any wires in the center console, preferably the radio harness.

Could someone please just tell me what color wires to splice into for each of these leads? I'm goin' crazy here.

Thanks

 

THANKS!!!

 

Well this didn't work for me. The wires all have good connections (I soldered everything) and I tested each circuit. Did I read there was something funny about the way Subaru handles the ignition switched power supply? Anybody have any additional input? I feel silly having this gauges that do nothing.
