I'm installing a micro tech ecu in a 1987 car with a 91 turbo egine and need to know where to tie in the alternator warning wire? I do not have the stock harness hooked up any more and need to know where to run the alternaor warning wire? Also I would like to know if any one knows which wire on the fuel pump is the positive and negative wires. There are four wires coming out of fuel pump area. please help...

 

You need to be studying the FSM wiring diagrams. All the answers to your questions are in there. If you don't have them, click here and download them in PDF format for free.

For the alternator look on page 50-18 for the wiring and the next page for the connectors. Extract the alternator plug and wires from the removed EFI harness and connect them back into the front harness connector they were originally fed from (FEM-01).

For the fuel pump look on page 50-36. The pump power is blue and the ground is black. The other two wires are for the fuel gauge and warning light (see page 50-40).
