I was wondering if someone could tell me how to wire our 94 s-10 blazer? We are going to pull a boat and had to put our own hitch on the blazer, but there are no wires and we are not sure how to hook them up. Can anyone help?

For a good professional job that will not give you any wiring problems.
Go to your dealer and get a plug in trailer wiring kit. And some parts places may have them to. They just plug into your rear wiring. Kinda like plug and play stuff on a PC.
Or if you want to save a few bucks now and pay for it later.
You can get a universal trailer plug in a cut snip and tie in to your rear wiring and have all kinds of wiring problems from moisture eating up and corroding and shorting out your your rear wiring.
Up to you. MT

I paid about $20.00 canadian for a Reese trailer adaptor for my 85. They're the same body styles, so I imagine that yours would use the same 1.

The plug that you use is located under the interior panel behind the spare tire.

I think that most people just feed the wires through the tail gate when required (which I didn't like)

If you want to know how I fed my wires through let me know.
