2nd Gen Non-Engine/Transmission digital gauge hookup

[HTRDHLR]

I have two digital guages, one fuel and one trans temp. The guages have a wire to hook up to the headlights to dim the guage by 50% at night. Without pulling off the dash where can I hook up that wire. I want it to only come on when the headlights are on not the running lights or fog lights. Any help is appreciated.

The best way is to pull the dash bezel, and then pull out the headlight switch. Just solder a your gauge wire onto the black wire with a yellow tracer. This is the running light circuit, and will act as a trigger to dim your gauge. Pulling the dash bezel is real easy... On a '99+, it just unsnaps--no screws hold it in. On a '98, there is one screw to remove, under the power outlet cover. On '94-'97, the mounting screws for the ash tray and cupholder hold the dash bezel on.



Just be sure to use a reliable wiring connection. Best way is to solder it, and then seal it with some splice tape. Don't use any Scotch-Locks or t-tappers. They will inevitably fail. :{



Hope this helps!

I didn't even hook up that wire, but my gauge is down under the ash tray so I like it to stay brite.

The instrument lights are fused by a fuse under the access cover on the left side of the dash next to the drivers door.

I forgot which one but you can find it with a volt meter.
