Fuelish Questions

The fuel pump wire is the 16 AWG gray one.

Once you get a hold of it you can trace it to verify it going to pin E of the fuel pump relay.


Happy Racing!

Re: Fuel pump power wire location

1) Remove the harness from the car before modifying it. It makes life 300x easier

2) As posted in your LTx/LSx thread its C100 pin G4, TAN/WHT. It didnt turn GRY until 90

3) What is that block in the first pic? Its not from the 3rd gen

4) The fuel relay is mounted near the brake booster for 3rd gen, not inside the car. Its the same pin for both the engine side and dash side of the C100. If it wasnt, they would never connect
