I bought this thinking I would cut off one end to replace the 5 pin connection plug on my trailer and use the other end as a dust cover. Would have worked except my trailer connector has 6 wires coming out of the plug. My fault for not looking closely. I could have made it work with an additional splice but I opted for ordering the correct Wishbone Harness Connector instead. In case you, like I, didn't know what a wishbone connector is, the difference is in how the trailer is wired. My trailer has a dedicated wire to each tail light for the running lights. Some use a single wire to one of the tail lights and then a jumper wire from the one tail light to the other. In that case, you can use the Wesbar Wunside plug.
