INjector Wiring
 

On a 88 turbo II all four injectors recieve a black and yellow wire, is this wire a ground and if so does it ground through the ecu, cuz i need to redo these wires and i want to know exactly where they go.

thanks for the help.

NO. It's a power wire coming from the Main Relay. That black/yellow wire that is. The path is from the EGI INJECTOR fuse to the MAIN RELAY to a plug called FEM-01 (maybe FEM-02, got me) then to the injectors. See the wiring diagram.

yah i wanna know what that damn fem-02 is...does anyone know...?

I said it's a plug called FEM-01. It's an electrical plug. It is part of the (EM) emissions harness and mates witht he Front harness plug. Thats what FEM stands for. See the FSM wiring diagrams.

The plug is on the emissions harness and is inside the cabin on the passengers side.
