Wiring diagram for s14 stereo so i can tap into it for my boost gauge wiring

[Drifternate]

I need to know which wires to tap into for my greddy boost gauge. I need 12v power source, an ignition source, a parking light source, and a ground. Any suggestions? Thanks in advance!

i dont have a s14 FSM here at work but... if you have an aftermarket head unit then you can tap into those wires from the back of that which i do know off top of my head.

yellow is 12v constant
red is 12v switched
black is ground of course
and orange is the illumination or parking lights.

Orange/green - Battery
Light blue - ACC/ignition
Red/light blue - Lighting switch
Red/yellow - Illumination
Ground - Anywhere metal! I think grey is the radio ground tho.

Thats for a 95 w/ cd player anyway...

S14 the parking lights are easy from the steering column...however there are two of them (one is the right headlight)...I believe the right for just the parking lights is the one is the one closest to the driver's door. If you need me too I can find out for you in a couple seconds.

Those wires in the kick panel are a bitch...they are like 40AWG and no slack (this is ideal from a factory perspective...low resistance). My door 'trigger' one got sheared in two by the previous owners T-Tap, which caused me BIG HEADACHES on my first alarm install. I had to pull the small junction box out, and tie in a new piece of wire. I had to tap it for my dome light supervision and door pin monitoring for my alarm.
