Looking to plug in hot wire with hot source while ignition is on. Black diesel recommended power saet fuse. (as I do not have power seats). THanks by the way. Do I have to cut the wire to that fuse or is there a simpler way to get a hot source, w/o sorting through wire cluster. I'm lost under there. Any ideas?

 

I used a relay and i highly suggest you do! that way the pump will get full 12v from the battery.
i tapped the stock LP hot to trigger the relay and ran a big wire from the bat-relay-pump. Works great hardest part is gettin to the LP wire, need 3 hands.
Yes the stock LP is still running. 23 idle and 15wot. Look at the bottom guage.

 

Install success!!!! Plugged pump into power seat fuse, only problem seems to be it is hot all the time. 19 psi @ idle, thanks for info. I'll figure it out.
