Can anyone tell me if the short data cable can be swapped over with the longer temp/rpm cable. The ends are the same, but not sure about the wiring. I don't want to fry my ECU. It would help with an installation I am doing.

I've used the medium length cable for the ecu-i/o board connection. I think it was intended for the gsu. Worked great.

Yep, They are all the same.

Thanks guys. Much appreciated.
