The marketing material for this light kit says it can work with or without a dc-dc converter. So like an idiot I played around with it to figure out how to get it to work with out the converter. The service manuals apparently don’t have wiring diagrams for this harness.

There are two “pairs” of voltage inputs on the harness. A red/black pair and a green/striped black pair. The red/black pair needs 48v. The green/striped black needs 12v. For some reason, this harness (or something in my cart) has connected the solid and striped black grounds, so both black wires need to share a common ground. The battery 1 of the bank can feed power to the lights and the entire pack will switch the ignition relay on to activate the harness.

I’ll figure out which dc-dc converter to order so that one battery isn’t singled out, but for now, I needed to have turn signals to meet the new local laws this year.
