Fuel pump wiring Q? I'm new here and I'm planning on swapping an LS1 and T56 into my '86 Z28. I've read almost everything on this and have most of it figured out. The one thing I am unsure of is how to get the fuel pump to work with the computer? My car was originally an LG4 so I know I need to get a sending unit out of an efi car, preferably a TPI car. I'm going to hang a Walbro 340 on the EFI sending unit because of the mods to the LS1 that is going in the car. Now to the real question, do I need the harness for the TPI fuel pump (keep in mind that I currently have a mechanical fuel pump). If I do need the harness I will probably go with the Racetronix setup. Can I wire the fuel pump with the LS1 harness somehow?
Thanks

Re: Fuel pump wiring Q? The fuel pump set up will be easy to wire. The LS1 computer controls a relay that you can mount anywhere. Then you just take the relay output wire back to the positive side of your fuel pump. The computer then controls the pump just like the factory did it.

Re: Fuel pump wiring Q? That sounds simple enough, thanks. Does anybody know if a TPI strut tower brace will fit with the LS1 in the car? I imagine it will, just trying to make sure before I go and buy one.
