Help identifying disconnected chassis wire

[iamtheliquor]

I recently bought a 1989 Accord LX-i coupe 5spd from a used car lot after two days it stalled and wouldn't start, so I diagnosed the problem and replaced the ignition switch and it worked! I've replaced the spark plug wires and plugs with NGK after repairing a stripped spark plug and I've run into two more issues! I found a RED/BLACK wire that splits off from another harness that might connect to the starter, but I can't find anything it connects to! The harness runs behind the engine and below it, and if my awesome paint skills aren't enough I'm uploading photos.

Thank you!

LOL. Yeah, pics would be good.

I also can't seem to find where this wire connects, I recently put my engine back in (A20A3) and cant find a spot for this. I deleted power steering, and ac I'd that makes a difference. Also when I turn the key nothing happens, the light on the dash come on but no crank or anything.. if I jump the starter the car starts right up, I'm thinking it has something to do with this connection maybe. Will upload pictures tonight
