Ok so I was changing the spark plug wires the other day and ran into this red wire that looks like it could be a ground of some sort but red usually is not. So does anyone kn ow where this wire goes.

If the pic does not upload it is a red wire that has an eyelet on it that is connected to the harness right under the negative cable.

Any ideas where this needs to be hooked up to?

Tuck it back in. You don't need to plug it in unless you need a constant 12v in the trailer harness.

WOULD SOMEBODY STICKY THIS PLEASE!!

Battery + (when connected to the proper place in the fuse block) for the trailer connector. It doesn't come connected from the factory.

if none of the lights work i'd check your ground
The ground on the trailer is good. Hooked it up to another vehicle and lights work. It's either that damn connector that makes it a 4 wire, or a fuse I assume. Just thought this would have been the reason if it wasn't hooked up.

Frustrating crawling under it to connect the harness. :doh:
