DenisAlmos Posted June 13, 2022 Report Share Posted June 13, 2022 Hi all, Is it possible to rewire the expansion pins to the OEM pins? I just about a new G4X to replace the old Motec M48 in my Group A rally car. The M48 had all the connections to the main connectors. I just don’t want to rewire the car so I would like to pin my G4X as the Motec was. What is the best way to do it? Sorry if there is already a topic on this subject, I didn’t find it.

Adamw Posted June 13, 2022 Report Share Posted June 13, 2022 What ECU are we talking about? A plug-in I assume? Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 18, 2022 Report Share Posted June 18, 2022 Our ecu wasnt designed that way, but provided the pins the Motec plug-in used as expansion and those same pins are unused on our header then you could possible solder in some wire links to connect our expansion pins to the correct pins on the header.

DenisAlmos Posted June 18, 2022 Author Report Share Posted June 18, 2022 That's what I was think to I'll do this, thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 18, 2022 Report Share Posted June 18, 2022 If you can find the motec document which shows which pins are "non oem functions", then Im happy to check if those same pins are available on our ECU and which IO would be best to connect to them.
