| I post this in the general forum back in February. It may be useful in the FAQ section so please vote it to FAQ if you can. This is the white connector near the blue ECU connector that you may need to de-pin when installing a new EFI harness. In case you forget which pins go where you can use this picture to help you get it straight by tracing where the pins go on both sides of the connector. I made this while tracing the wires needed to power the ECU and to connect a diagnostic interface to it in order to do tests with the ECU in my home. Thanks much! Gary
