PDM Electrical System Kit Wiring Diagram and Parts

I have a failed hand controller interface (HCI) on my Mastiff. It was installed by a previous owner and I do not have any documentation on the system. I believe my HCI unit is bad and I cannot find a place to purchase a replacement. I know the purpose of the HCI but I have no wiring diagrams to verify that it really is the HCI that has failed. Furthermore if I did have a good wiring diagram I could build my own replacement HCI. Any ideas on where to get the HCI or wiring diagrams? Thanks

Thanks for the information, it sounds like there is a need for a replacement. I will do my best to try and reverse engineer the HCI, then build it and test it. Thanks again.

So I have my bike back up and running. The HCI unit has failed to supply my VFI module with 12V power, it was hovering around 2.3V. Using Mickeetwo's wiring diagram I have a good understanding on what the HCI is suppose to do. Since only my Run and Stop functions were not working I decided not to recreate the entire HCI. I choose to just add three micro relays (2x SPDT & 1 SPST) and bypass the HCI for the Run and Stop functions. If I could figure of the part #'s for the Molex looking plugs, I probably would recreate the HCI unit one day. Although it would be a improvement if I replace these cheap plugs with sealed plugs.
