Hello, I’ve recently bought a GT650R and I need a new wiring harness. I’ve spoken to Marcel about it and he said that I have a discontinued ECU. It has a mitsubishi logo on it. If anyone can help me make or find a harness, that would be amazing!
keep an eye on eBay for one, but other than that it would be easiest to repair.
Get yourself an 8×4 foot sheet of ply, mdf or similar. You can then pin the current loom to it, mark all the connectors and then do a continuity test for each wire.
