So I have been doing some testing, and by using a OBDII reader I can see that the speed sensor in the gbox is reporting a signal to the ECU. So the issue is either I have an incompatible signal coming out of the ECU bulkhead connector (or no signal - can I test this?) or a faulty gauge.

Not sure where I will go next?
