I was looking under the hood of my new (well, purchased new) '04 TB EXT, and noticed a red lead wire with a post connection type that clearly connects to a post on the the fuse box (facing the battery) but it is not connected and held back onto the wiring harness with a clip. I hooked it up but can't tell what it does so I left it off.
I'll try and take a picture and post it when I get home, just curious if anyone knows. It's not anything obvious like alarm, PW,PL, etc because EVERYTHING works.
Thanks in advance!

I would be interested in seeing a pic of what you're referring to.

That is used if you completely hook up the trailer tow wiring.
That would make sense.Originally Posted by EnvoyFan2

Which one is it on the 7-wire harness, accessory?
