Was wondering where to get a power source for the pyrometer on an 03 Dodge?

 

Fuse panel would be easiest. Somehere that always has power like the power seats.

 

Geno's garage painless wiring kit You wont be sorry Ive allready used up all the circuits running gauges,a cd changer,
back up lights and trailer circuits. but it sure makes the job look more professional(ok wait a minute I am a professional electrician). I resisted and tapped into fuses at first with tap and ended up pulling fuse block to tighten connetions as taps spread the spring clips , it wasnt pretty. BUY THE PAINLESS WIRING KIT IT REALLY IS PAINLESS

 

napa sells little fuse taps to get in a circuit that you choose and its not messy and your still fused (as long as you tap the correct side)

 

AutoZone has some taps that have a fuse for both the original circuit but also adds a new circuit with its own fuse.
