What is this???

Forgive me if this is a stupid question but what is this? It's dangling to the left of the MAP sensor. Can't find anything it's supposed to be plugged into.

I think that's where a mechanic would plug his computer to, so he can bump start and monitor engine stats, ECU functions etc.

yeah... It was called OBD 0.000001! With the proper equipment, the mechanic could tell you if the engine was running, or not. Also, if he plugged in is computer, and turned on the lights, if he went to the rear of the vehicle, he could determine if the tail lights were working or not. I love old technology!

What year is the jeep? My 90 is a tbi with a similarly crappy renix system. However, snap did make a unit that would read the computer and give you real-time info when the car was on. Was actually pretty cool. And you can pick them up for under $200.

Whatever it is it doesn't plug into anything. I also have a 95 that I've owned since 98 I went out to have a look and yep it's just sitting there.

It is not for OBD1 scan tools
My '90 had the OBD1 port on a tab on the other side of the battery.
My. 93 has it on the driver side (see pic) above the outside master cylinder area.
The OBD1 port is not square either, it's a fat angle as seen in the pic below. This interfaces with the Chrysler DRB and other scan tools .

As for what your plug actually is? I'm sorry I have no idea..... My. '93 does not have that plug.

I believe that is the plug sticking out of the main harness that the A/C system would plug into. My 87 has the same plug hanging in the same spot, and it doesn't have A/C.

That is what I figured it was since I have the diagnostic port over by the battery for the OBD1, and I have traced all of the other wires in the main harness when I was looking for a short/broken wire. I could be wrong, but there isn't much left that it could be at least on my harness anyway.

That's actually a connector for a 12volt relay to plug into. It's probably for an option you don't have or a smog item not required. I only know this because I happen to be gutting and rewiring my 89 this weekend. And I found a few of those with relays supporting various things. If it never had a relay in it and everything is working, I wouldn't worry about it. Just let it hang.

I kinda agree, if you ignore the smaller holes, thats perfect for a relay.
Smaller holes might be for lock pins for the plug, or similar.
