This wire comes off my 2.8l no idea where it comes from http://i857.photobucket.com...DE41_zpsef1b2a47.jpg

Try photo-shoping an arrow onto the pic so you can identify which wire you are talking about

Is this what you're asking about?

Flux capacitor override switch wire. Appears yours is non- functional. Be extremely careful t speeds over 88mph. But I will look at mine in the am and see what is really is .....

I say either part of the E brake or a broken off ground wire. Larry

yes that is the wire. im not sure where it goes .. good thing is that the car still runs

That looks to be a ground wire that attaches to the lower frame rail, drivers side near the evap line bracket.
Trace the wire back to its origin, it should attach to the trans bolt near the starter.

I'm pretty sure that's the e-brake cable that's broken off.

the e brake works its gotta be a ground wire

I think OleJoeDad is right. I have one that looks about like that, except it's attached to the frame rail and pulled loose from the transmission. You can see one end bolted to the frame rail and the other end near the exhaust down pipe, in this pic.

should i even worry about it?

No, but you should replace it.
