dbtk2 Posted March 21, 2004 Report Share Posted March 21, 2004 I am going to install an aftermarket boost gauge in my TSTE. I was wondering where I need to tap into the wiring for the light. (so the light in the gauge will turn on and off with the dash lights/headlights) Shawn Quote Link to comment Share on other sites More sharing options...

Z34door Posted March 22, 2004 Report Share Posted March 22, 2004 i went to the closest thing to the gauge.......... IE on a GP would be the headlight switch...... and i tapped into the back of the plug till i found the hot for the lights so the dimmer will work with the lighting on the gauge.

no1kicker Posted March 22, 2004 Report Share Posted March 22, 2004 yeah headlight switch would be a good location depending on where the gauge will go. I think the brown wire is the park lights signal, I can double check. Or do you want it to dim along with the other lights? Quote Link to comment Share on other sites More sharing options...

It would be nice if it would dim with everything else, but just lighting up when the lights are on would be like 1000 times better than nothing.

92turboLE Posted March 22, 2004 Report Share Posted March 22, 2004 the grey wire with a black stripe (if i remember correctly) is the dimmer signal, which should power up the light in the gauge, but im not sure if it is the same wire that will allow it to dim, i'll look in my nifty little wiring book when i get home - Justin Quote Link to comment Share on other sites More sharing options...

If you could look it up to make sure it'll dim that would be great. Thanks, Shawn Quote Link to comment Share on other sites More sharing options...
92turboLE Posted March 22, 2004 Report Share Posted March 22, 2004 no problem, i will do that when iget home. I know that the grey wire sends a + voltage out when the lights are on that activate the gauge light circuit, but im not sure if that is one-in-the-same with the dimmer signal, but i will certainly check and try and find out for you. Otherwise, you could tap into your gauges themselves. The buls are clip in bulbs and would be very easy to tap into. you would have to pull the cluster and remove the plastic housing on the back of that (7 or 8 Torx screws) and you will see the bulbs. Just dond use anything that is the warning lights (they are easy to find) - Justin Quote Link to comment Share on other sites More sharing options...
