This weekend I accidentally ripped the cover off the OEM 7pin trailer plug on my Screw. Does anyone know of a place other than the local dealer to buy this? Dealer wants almost $70 to replace just the plastic!
I could just replace the whole end with a cheap aftermarket one but I would rather retain the factory plug.

 

You can get that entire assembly for probably 9.99 online. Look around for vehicle 7pin trailer harness or outlet. You don't want the trailer side obviously. There are literally only a handful of wires, 7 actually including the middle pin, just cut and splice, very easy. Definitely solder and heatshrink the connections however.

You can get a 7pin to 4pin plug, where you can use the 4 pin outlet to plug into the trailers 7pin. You will lose the 3 pins: constant 12v, the accessory, the trailer brakes (if avail) and I believe thats it.
