Amazon says this works, but you may want to double check it first https://www.amazon.com/Hopkins-43415-Simple-T-Connector-Wiring/dp/B0002Q7ZLO?tag=viglink20350-20
The dealer actually sells the "back half", which connects via plug, like right underneath the driver's side slightly fore of the wheel well? I seem to remember accessing it by pulling interior panels out of the cargo area, long time ago, but definitely sure it was a dealership part, check with them and they may even be able to show you on the screen where it goes. Mine has worked perfect for 7 years since. Doesn't hurt to spray it with electronics cleaner and some dielectric grease on occasion, and keep that cover on.
That's exactly what the kit posted above on Amazon is.
Like I said, literally plug and play. And you're correct, it's to the back of the vehicle (behind the wheel well) and under the panel. Took me about 30 minutes total to get everything done.
Nope, not at all. It was one plug only. Around $35 if I remember correctly. Of course if OP doesn't have any wiring at all, then totally worthless to him.
I ordered the one from Amazon without my 97 having any wires. When I click on that link it tells me the date I ordered it last and asks me if I'd like to order another one.
The Amazon kit is what he needs to get. It has two parts. I only used one part, which was ONE plug.
Don't tell me what I know, Travis.
