Hey guys been looking for a wire diagram to assist with putting in some gauges, my bud and I are going to try to set up an coolant and oil temp isspro gauges, the plan he has is to put them on the the sender units for the data. Bought the book from auto zone for wire diagrams but it not showing what we need. If anyone has done this before your input is encouraged. Thanks bombers-

 

All you need to wire into the truck is ground, power, and a light source. The ground is easy, for power just start searching in the fuse panel under the dash for a keyed power source with a multimeter. For lighting I'd wire into the factory dimmer switch. Pull the dash off and pop the dimmer section out, there's only a couple wires going to it, find the one that has variable power as you roll the dimmer switch up and down and you've got it. It's quite simple.
