Why Struggle? It’s as easy as 1 , 2 , 3
Color: 14AWG-2 Lead
Love how simple the harness is! Bought this for a set of ditch lights for a 99 4runner. I love how much wire they give to let you run the wire to where it needs to go. 1st time buying and will come back for more in the future.

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.
