which wire under dash for ACCESSORY?

wiring up gauges still..

 

would you be talking ignition???

 

it just says a source that will stay on during cranking.. and off when trucks off.

cant remember what i tapped into on the lightning.. its raining here, so just wanna be able to go out and do the correct one all in one shot.

 

that would be ignition in other words whats on when the key is on, depends on what your installing i can tell you whats close.
what are you installing

 

power for my air fuel gauge.. already got the chassis ground, and power for backlight, which goes on with headlights, and dims.

 

tap off the radio fuse, you can look in the manual to see which one it is, use the fuse box by the drivers door inside, youll find it, if you have any trouble finding it, i can snap a pic.
