I've installed my new temp gauge and it works great. Now I just have to connect it's light. The instructions says to check whether or not my vehicle's dimmer switch governs the ground wire or the power wire for the lights. I'm looked at the wiring diagrams in the FSM and I *believe* that it's the ground.

Would someone kindly confirm this, or better yet tell me exactly which wire to tie in to?

Thanx!

edit: Oops! She's an 86 GX.

 

Its a positive trigger and it is Red/Green found at the back of the gauges, the light switch, the turn switch, the hazard switch, the wiper switch, and the cig lighter

 

Positive. I believe you want to connect one wire of the guage to the red/green wire coming out of the headlight switch, then ground the other one. At least I think it's red/green.

 

Thank you!

 

bah just give it 12v. my lights are on all the time LOL
