Wiring indiglo gauges
 

Hey ppl just need to know where the best place to wire the guages, the positive and the negative like what should i splice them too

i would say

+ to ILUMINATION wire (most of dash lights, cigarette lighther light are hooked up on it and u could adjust brightness using stock know on headlight switch...atleast aftermarket gauges are getting connected to this wire)

- ground

Well the gauges usually have their own dimmer. You would want to hook it up to the switch so when you turn the marker lights on they will come on. The first position of the headlight switch.

What wire is that? I don't know, that's why I'm searching old posts. :)

I honestly couldn't tell you...it's been a few weeks since I've done mine. I wired mine into the headlight switch for that very reason. Works fine. I just used a volt meter to probe and discover which line gained a 12v signal after switching on the parking lights.
