Got A SS Posted April 9, 2004 Report Share Posted April 9, 2004 Ok thanks to all the help on here I got my hitch figured out. What do I need to buy to wire for a trailer? I understand the SS is already wired for a trailer brake so all I need is the harness? I see a bunch of plugs at the auto parts store for trailers, where do they plug in? Lots of ??'s but I have never messed with this stuff before. Link to comment Share on other sites More sharing options...
SSminneapolis Posted April 9, 2004 Report Share Posted April 9, 2004 there is a plug right next to the hitch, underneath the bumper on the left i think. should be a round plug. most parts stores will have the plug i think they run about $20 or so.

jeffnjill Posted April 10, 2004 Report Share Posted April 10, 2004 I'm not sure what you are asking, can you be a little more specific on what type of trailer harness you are looking to wire up? If you are going to haul trailers over 1000# you should definately hook up the 7-way round camper-style plug. If you are only hauling trailers without electric brakes, you could get away with a 4-way connector that gives you turn signals, brake lights, and marker lights. But, what happens when you decide you want to haul a travel trailer for a friend? Definately go with the 7-way... Link to comment Share on other sites More sharing options...
Got A SS Posted April 10, 2004 Author Report Share Posted April 10, 2004 Yup it will be a trailer with brakes. 7 wire plugs in where? Link to comment Share on other sites More sharing options...
leupy Posted April 11, 2004 Report Share Posted April 11, 2004 When I drove from PA to TX, they sold a 7 wire (our stock plug) to 4 wire (most of U-haul trailer type) plugs. It was like $5, so if you're having a hard time finding a 7 wire plug, or it's too expensive, you can get the converter plug and do it up that way. Just in case that was in the unknown column...

n2opwr Posted April 12, 2004 Report Share Posted April 12, 2004 If you are ever hauling a trailer w/o brakes and it has a four wire plug, this is what you need. It is $6.96 at Advace p/n Litemate 47355. Link to comment Share on other sites More sharing options...
desrtrat Posted April 12, 2004 Report Share Posted April 12, 2004 wal mart has a 7 pin female connecter plug that mounts to the truck and also has the 4 pin flat connector all in one. flat pins are just left of the 7 pin on the same bracket.

jeffnjill Posted April 13, 2004 Report Share Posted April 13, 2004 Sorry I haven't gotten back to this sooner, I believe these trucks without the hitches installed at the factory have the wire harness tucked up inside the rear of the frame somewhere. It has a connector on it that you buy the plug from a gm dealer and plug into it. and wire it into the 7 pin camper style plug. I may be wrong, send Zippy a PM and ask him for the part #'s to take to the dealer. Link to comment Share on other sites More sharing options...
