Yah I hear ya, wiring, tuning isn't my high point either. lol

I have my pump wired into a keyed hot, grounded, thats it. I didn't go threw the relay and all that.. It works perfect, is holding up just fine.. What about just running a bigger intank then my inline. doing away with the inline??

Do you have an intank or inline now? One intank will run with the stock wiring, but an addtional pump will need a relay to be done correctly. The wiring is not very difficult.

I am running a single 255 intank. Probably good for around 500whp. There is a bigger pump out there (420?) that may fit in the tank?
