Hi ya'll, just finished installing Dipricol EGT and boost in pillar mount. Truck is a basic model without all the electric gizmos.<br><br>Question is which wires to use for gauge lights so they dim with the rest of the dash. After quite a bit of playing with the meter and a test lead I wound up using a brown wire with orange trace that was on the top of the switch connection block and a black/orange of the rheostat looking thing on the bottom of the switch. This sound familiar or right or anything to anyone? Didn't let the smoke out anywhere I noticed, just wondering.<br><br>BTW, the Haynes manual I got seems to show the same wiring diagram for the multifunction switch and the headlight switch. All I know is that my headlight switch connector looks nothing like what they show.<br><br>Thanks,<br>Rob

 

Just tap into your fuse panel in the cluster A I believe with a fuse tap and then ground the ground wire to anything metal in the truck.

 

It should be your #5 fuse to tap to dim the gauge lights w/ the rest of the dash..... <br><br><br>Tony

 

When I installed my gauges, I picked illumination voltage from a 5 amp<br>fuse in the panel(just be sure to get the fused side). It was an orange<br>wire. Power for the pyrometer amp was from a 10A fuse labeled for the<br>dash gauges, and I think it was white w/orange stripe.<br><br>HTH

 

Just added a trans temp gauge from autometer and discovered you can have a much cleaner install by picking up a $7.00 &quot;add a circuit part&quot; at your local auto store. This thing just plugs into your circuit board at the &quot;illumination&quot; 5 amp fuse and has a single wire attached for the positive wire of your accessory. It allows your accessory to be protected by its own 5 amp fuse. I think it is a great way to add accessories without mickey mousing. IMHO Try Auto Zone or Pep Boys.

 

hey just tap into the light in the ash tray, thats what I did, works like a champ. Dims and everything.
