Almost dont with my nitrous kit and I need to wire a final wire from inside my cab to the solenoids and battery under the hood. Where should I pull this wire? any ideas?

 

There is a thick cluster of wires coming out of the fuse pannel under the hood going through the firewall next to the master cylinder. I folded a coathanger in half and ran it through grabbed the wire and looped and taped it to the hanger and pulled it back through. Worked for me.

 

Thats the same one I used also. Helps to have two people there so you can have one inside on on in the engine bay to pull it through.
