Trailer Hitch Wiring

[mace01]

Well, I know this is nearly unforgiveable, but ….
After owning it for almost 2 days I’m planning on putting a hitch on my 2007 Grand Prix GT. Mostly I’ll be using it for my bike rack, but I have a little utility trailer so I’ll need to wire it up for the usual flat 4-wire connector. I’m not sure what I actually need to get this done. Thanks for any help you can give!! - Jim

Just buy a little kit with a converter and they just wire into your brake lights. Some need a power wire going to the battery.

I've seen a few of the boxes, but not sure which to buy. Any ideas?? - Thanks
