I just got a 1996 Rav4, and I need to buy myself a hitch and wire it up. The aftermarket hitches, ball mounts, and balls available seem to be easily understandable, but I have no idea what kind of wiring I need to get or how to attach it when I get it. There seem to be dozens of options on each site, ranging from $12 to $50.
The trailer I’m going to use has a 4-pin connector on it.
Please, oh wise dopers, help me understand which wiring doohickey to buy, and where it actually connects up to my automobile.
