I've been searching around and I can't find a pinout with the colors.

I'm about to repin my 746 to 730 and i'd like to know what the colors of the wires should be on the 746 and 730.

I'd appriciate it if someone could post this information for me.

Thanks,

For the harness colors go over to the diy-efi.org site , gmecm, and under ECMs there are wiring diagrams.

Your a good man, thanks.

Think i bumped into something here. I believe this is what I am looking for.

'92 F body 5.0 and 5.7: Page 1, Page 2, Page 3, Page 4, Page 5, Page 6, Page 7

On page http://diy-efi.org/gmecm/ecm_info/1227730/


Now that I can see the differences between the 2 ecms. My goal is to make my wiring look like the 730's wiring diagram.

Am I correct in my theory? It seems much easier to understand than this site https://www.thirdgen.org/techbb2/sho...readid=216453. Unless I am totally missing somthing.

 

Yes, just need to change the wires to the new position in the connector. MAT is still MAT, may just go to a different pin (and so on with the remaining).

There is a '747 wiring layout there too. That is close to the '8746 but not exact.

Has anyone ever fabbed up an adapter for this kind of swap?
