OK, so I know this topic is old (like me & my car), but is there any chance anyone knows the part number or where I can get the 10 pin male plug that would fit into the Trailer harness socket, sure I could tin wire (if my hands didn't shake much - alcohol or age?) but I'd prefer to get a plug and wire it up and then plug it in. Before anyone says "Google it" I have for about 3 hours last night and I had nightmares of drowning in electrical sockets. Great site, grovel, grovel. Hey, question, if the brake light warning is on but they both work, is it the brake light on the window? - that doesn't seem to come on when I put a 10lb barbell on it.
