I just sold my 2015 Pro RMK and I kept the PIDD gauge off of it and sold it with the stock display. I now want to put the PIDD on my 2018 RMK and the wiring harness doesn't match up exactly. The old harness has two connectors for the headlights, which I am sure I can cut and splice the new connector to. However, there are two black plugs that look like diodes and I don't dare plug anything in until I know I won't burn something up. Any body know?
