1981 CJ7 6 cyl manual wiring

Finishing AMC 360 HEI installation but can't identify one wire. There is a long black wire coming from the transmission. It has an ell shaped connector that goes on a screw. The only diagram I have is for a '79. Would someone please help me identify this wire? Can't figure how to attach a pic. Tks Ralph

Thanks for responding. I read link about pictures but don't see the "paper clip" Surely some one on here knows where this black wire goes or has a diagram for a 81 CJ7

Well usually there is only the backup light wire's' on the tranny. One from power and one to backup lights.

Are you sure it doesn't go to the t-case? There is a single wire for the 4WD indicator light. And it has a 'L' shaped connector.

Here is a link to the wiring diagrams for an '81

Thanks John, Mystery solved. The black wire comes out of the TOP of the plug on the wires behind the engine going to the transmission/Xfer. There is no corresponding wire coming out of the bottom of the plug. If the Jeep was an auto trans the black wire would have gone to the starter relay from neutral safety switch. It's been well over a year since I removed the 6 cyl so I can't remember but obviously the wire wasn't connected to anything.

Thanks for the wiring diagram
