I cant seem to find the correct wire under the dash to power the gauge. I have tried a constant power source and it dosent work. I have read that i need to use a ignition wire. But looking under the dash i see many blue and white wires. I have all the vac. lines hooked up but the gauge dosent move at all when i try pluging it in to a power source. Help on the correct wire to use.


Thanks

 

I have tryed black and gold = no good.
tryed white and blue = no good.
tryed moving the ground = no good.

Help

 

Pink wire...I'm pretty sure in the ignition harness there is a pink wire that gets power on ignition that my gauges are running off of. I'll double check in about an hour when I go to my car.

 

Thanks for the help. Autometer said that it has to be a non constant power source. One that doesnt get cut off a ignition.

 

Get some fuse taps from autozone or kragen or whatever and get the power through the ignition fuse in the block of fuses behind your dimmer switch.
