I have a Defi Racer boost gauge and oil pressure gauge I need to install. I've searched all around the forums to figure out where I can a wiring diagram for the ignition harness. Can anyone tell me what the color of the wires are for a 12v constant power, 12v when the ignition is on, a 12v illumination wire when the lights are on, and a ground. If anyone can help me out figuring out what the colors of the wires are, I would appreciate it!

 

i could help you on the ignition wire but illumination id have to look into. ill get some pics for ya tommarow if someone els doesnt.

 

where do you want it tapped? the best thing to do is use a multimeter and you will be sure rather than going by colors.. I tapped power for my EDFC before on my radio harness and some wires are stripped with 2 colors

there's a post in here with wiring diagram, ill try to search again.. but i advise you to always verify it with a multimeter, or else you could drain your battery if you tap it wrong

 

all my taps i made in the driverside fuse panel inside the car, and yeah a multimeter really helps.

 

I will definitely use a multimeter, I just wanted to know where to start when I tested. I'm going to be mounting the gauges in an a pillar pod, so wherever it would easiest to tap into.

 

im a little curious why you want to use an illumination lead.

 

the easiest is the fuse box on the driver's side if you want the a pillar gauges

 

it might be a defi gauge feature maybe lighting effects or something

 

I believe it is. My guess is the gauges dim when the lights are on.

 

even still id rather just hook it all up to a 12v switched source(ignition). simplify things a bit. thats just me but to each their own.

 

ahh ic, the aem's that i got have a photo cell that controls dimming.

 

I believe if i do what you mentioned, I'd lose the shut down ceremony that the defi gauges perform.

 

^^ I want your gauge

 

ill look into it for ya tommarow and give you wire color and location.

 

Thanks crush.

 

btw what year is yours

 

2006.

 

iv got an 07, i dont think the wireing really changed as far as illumination and other 12v switched sources except for the harness to the computer but i didnt go anywher near the computer for the taps.

 

where are you exactly looking for the main feed? did you tap behind the kick plate?

 

yeah, the one thats right by your left knee when driving.
