FASS system wiring?

I just got my DI performance/FASS system and no clue where to wire in the supplied harness for the fuel pump. Where's the best place to tie into?

wire it to the fuse box on the fused side so it will blow if theirs a problem or if a pump burns up.

Re: FASS system wiring?

I have seen different meathods, the neatest install I saw was a relay from the oem pump. they probaby pulled supply feed from fused circut off the battery. but using the relay powered it up as soon as the oem pump would have.

Thats exactly how the FASS system is built, a realay activated by the stock pump wires turns on the new hot wire that is already fused, so it could be wired in to the fuse block but there is already a fuse on it so its not 100% nessicary it could be wired right to a power source no prob

Re: FASS system wiring?

why would you do that when they give you a relay?

well I guess it wasn't such a novel idea after all.
he probably just used the parts out of the box and the directions i guess
...here i thought he had a great idea...
