Hope you've recieved my email, sorry for the delayed reply, we've been crazy busy here lately. Ok, for others who may have the same question, the red wire on the 5.75" HogLight is for the park light. As the LED's utalise a single controller board inside, all of the negative/neutral signals go out via the main harness connection. This means only 1 wire is required for the power input. To hook it up, just connect it to the positive park wire on the harness. It should just plug in.
The connector that was mistakenly sent in the first shipment was for our 7" units and the 2nd was a wire tap. However for the Scout, you should be able to directly plug it to the positive signal and then the park wire will work.
Am glad you're back on two wheels mate. Safe riding. Cheers! Nate
