That makes sense but i cant remember how many wires there are back there. Is there just the power and ground or another switched power that the stock wiring uses. I havent pulled the pump out yet and cant remember since its been a few years since i put the walbro in. If i remember right, its just a power and ground but not positive, thus the reason why i asked which wire to hook to.

 

It is just a power and a ground, it is not relayed at the pump.

 

I have the battery in the trunk so the wiring would be easy but increasing the voltage is not my only concern. The second part of the story is Constant volatage. This should help linearize my tuning a bit and avoid loosing pressure as the volage drops.
