Are there any wires that I need to find/trace from the engine wire harness to the Fuel pump/Tank? I have not seen or have not been able to locate any so I wanted to make sure. I will be pulling the engine out tomorrow but didn't want to get caught in the middle because wires are still attached to that. I see that that this harness goes straight to the back on the driver side and I am thinking that this is where the pump might be connected to but none of these wires are tied to the engine harness. I was assuming that the pump harness would be part of the engine harness but maybe totally wrong. thanks.
