So, I have no experience with this brand. But, wire is wire. From the list provided, and the description(12 circuit) one could decide on the following checks. 2015-62=53? Are you working on a 53 Chevy of some kind? Truck? No I am not a smart [censored](well not all of the time) I just need to know. Is there any power to the harness at this time? It helps if you use an Ohm meter or a Volt meter. Assuming no power(Safety first) Use an Ohm meter to find continuity from the fuse block to either the AC compressor wire or the Fan fan wire. The fuse for each should be marked. Got continuity? Good that is power. Use to run the backup light switch circuit. No? Check for continuity to the key switch. Good, that is power. Use as needed(should be on the "ignition/run" post.) Make notes, add a label. It will help later. Best, add a fuse. Test with a power supply(charger works) before you put the battery in. Others will have some suggestions. We are friendly most of the time. Enjoy the project and let us know how it goes. The wires for the temp sender(1). Oil sender(2). Tach(5) won't be used if you have original Temp gauge(mechanical), Oil gauge( also mechanical). No Tach in the original AD truck. You could add one...+ side of the coil to Tach, light to dash...so where is the Tach wire in your kit hooked up? I don't know. If you have an inline 6 and no AC I would use that wire. You might save the Fan, fan for later use? I do hope this helps.
