Just hooking up my autometer pyro, the thermocoupler and gauge light are hooked up. Now, I'm hoping Ive hooked up the 12v switched power source in the right spot before I test things. The red and black(18-20 AWG?) Black went to ground and I put the red to the 10 amp fuse on the lower side for the radio.
Does anyone have any suggestions for a better place for the switched 12v source???

 

I used the 20 amp fuse thats used for the cig lighter but you should be fine with that I would think.

 

I wired mine into the switched wire in the back of the radio.

 

I had an empty switched location in the fuse bank. It was towards the top of the bank. Who knows my truck didn't have a lot of power options it may have a hole for windows, etc.. But try there
