LS Swap quick fuel power questions

Donor car is a 1987 TPI, swapping in a 2002 LS1.

I'm using an aftermarket fuse block and relay.

Q1: I would use R9 (Fuel Pump Relay Control [Primary]) From the ECM to signal the Relay on?

Q2. Where would I wire in the fuel pump power wire? I cannot find it anywhere in the C100 schematic.

Thanks a lot.

Re: LS Swap quick fuel power questions

You have ample fuses in the stock fuseblock, why add another?

1) Yes, 12v leg

2) C207 D TAN/WHT
