I think it is the ground. There is no ground in the harness, it is a separate black wire (so I have been told).

Yes, if your radio is not grounded it will not work at all.

alright, but that one doesnt have a screw mount anywhere on the connector. Where would it usually be connected?

On mine it is part of the harness but its also an 89. If you are putting in a new radio check to see if the ground is in the harness. may just want to post a pic of the back of the radio

the black wire on your new radio harness has to be grounded... whether that happens through your oem wiring or you simply put a screw through the dash and put a ring terminal on the end of it. make sure you have a ground and then see about that radio working....

That black wire with the female disconnect is the ground. You can either cut the terminal off the end and splice it with your stereos ground wire or run a new ground to chasis from the radio. If you do that... run a 12 gauge wire. It's always better to have a larger ground and sand the paint around your grounding point on the chasis too.

I had a 95 and the ground was separate from the harness and had that terminal on it. I cut the terminal off and used it for grounding other accessories and ran a separate ground for the radio.

You don't need to extend it to the frame. You can just ground it to the dash frame right under the radio. As said above just cut that terminal off and put a ring on it then bolt it to the dash.

ground it to your firewall. Its easy to reach with a cordless drill. Mount it up high so you don't see it or kick it loose. It might be your contant wire. This is a wire that when you program your radio or your clock has power to it all the time. If you clock and radio stations need set every time you turn you jeep on then that is what it is. If that is the case run it to a constant hot wire. Or even to the battery. The radio should have come with a manual that tells you what wires are what. Some radio's also have an extra wire for a power antenna. Could be that. But if everything works as is and the memory of the stations works. Then forget about it. Throw some black electrical tape over the metal end and call it good.

THis is going to sound bad but, did you disconnect the batt to start the work by chance and not reconnect it?

IVE DONE IT!!!!


You have double checked the fuses?

Do you even get a clock?

Did you try with the keys in?
