Hi Everyone,
I would appreciate some guidance / information on how to connect a Curtis 1313 Handheld Programmer into the Curtis 1239E motor controller (Motor is a Curtis AC51). On the controller side I am clear on which wires are the correct ones (I will attach the schematic), I believe that the harness had a 4 pin mini molex connector. I removed the 4 pin connector and pinned the wires into an 8 pin connector for my battery display. Everything works as expected, no issues. The issue now is that I need to do some programming, I purchased the correct Handheld Programmer which has a 4 pin molex connector. I need to build a cable between the 4 pin on the Programmer and the 8 pin that is used for gauge. The good news is the they both have 4 wires, the bad news is I don’t which one mates with the other. I will attach a picture of the handheld programmer 4 pin with the visible wire colors.
If anyone has any information I would greatly appreciate it.
