I’m using an 1989 Mx-6 Turbo wire harness to do an efi conversion on my mazda b2200. I have all the wire harness diagrams, but none of them explain this white connectors pin out. It’s obviously needed as it supplies the power to the ecu and accompanying electronics. Can someone help me?! I believe I’ve almost got the ecu completely lined out, but if there is a spread sheet that explains each pin that would be radical too. I truly appreciate any and all help. As this has been a frustrating part of the build.
