Quality but short.
Color: 14AWG-2 Lead
Quality built harness but I wish they would make the switch wireing long enough to go from the dash to the battery area on film size vehicles.

Great product
Color: 14AWG-2 Lead
A lot cheaper than getting wire, a relay, connectors, fuse, etc. Great durability, like the extra coating over the wires. Mounted the relays in a spot where they get totally soaked. They were sitting in water when I tested them out they works great so I’d say water resistant is an understatement. Overall great product.

Makes wiring lights faster and cleaner
Color: 14AWG-2 Lead
Harness is well insulated and much easier to use than running wires separately. I’ve installed 2 kits and they work well. Greatly simplifies wiring auxiliary lights on a vehicle.
