Trailer Wiring Harness Question

Is possible on a 98 to wire up a trailer harness without buying a tail light converter kit?

Just got a canoe and kind of need to use a trailer with it lol

You need the converter because of the separate brake lights and turn signals on the ZJ...

all ZJ's came with the trailer wiring in the back, all you need is the relay pack and the trailer harness pigtail from a tow package ZJ. literally plug and play with the 7 pin adapter that has the 4 pin capability, and all you need is the extension from the trailer to the 7 pin adapter.

basically, go to the junk yard, find a ZJ with the factory trailer tow harness on the hitch, remove the plug, follow the wiring up the body, there's a rubber plug to seal it. remove the spare tire, remove the panel behind the spare, that's where the trailer wiring lives, the relay pack plugs in to the rectangular black plug below the window, about middle of the way of the glass, it may be tucked up under the metal, it's there just look (unless you have a 1993, some 1993's had trailer wiring on the passenger side about the same location...mid way below the glass, my 1993 has it like that, but my early 1993 i had over a decade ago had it on the driver side like most ZJ's). you might already have the relay pack, you might not. Keep in mind any year ZJ relay pack will work, I have a 1993 and a 1994 relay pack in my 1998 5.9's. i have a 7 pin harness from a 1994 in one 5.9, and i have the 7 plug pin harness in my other 5.9 from another 5.9.

i use that adapter for towing, yeah it's big but it covers just about everything I'd tow, used it to pull my jet ski, enclosed trailers, and a car trailer.

A lot of ZJ's aren't tow ready and don't have the wiring for the relay pack. It's common but not universal.

I have the relay pack, Where do I get the harness that goes from it to the hitch?

I just recently wired mine and this was the best deal I good find, http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

none of the auto parts stores here had one in stock they were special order, I cut the flat four pin connector off and used a six pin round connector and installed it permanently under the bumper, I didn't want to have to drop the wires out the rear hatch door when I wanted to pull a trailer...
