What is this?

[Cubey]

I have no clue what this is. It's been dangling loose on the driver side between the battery and firewall, but I only just noticed. It's nowhere near glow plug wiring, so being yellow and heavier gauge is a coincidence. I don't see anything around it could go to. It was hiding behind the big plastic connector there in the picture behind the white plastic in line fuse holder

Looks aftermarket to me. I've seen similar looking connectors before, but they were inside the power switch to a sander that we use for sanding wood at work.

It's possible, but it looked like it was going into the factory harness. There's a lot of leftover wires from past extra equipment around in here. I guess I'll just wrap it in electrical tape and leave it alone.

I have the batteries unhooked right now (neg), because I'm running 10 gauge wires into the dash for addon 12v outlets and usb charging ports, hence not worrying about it being close to the positive terminal for the photo.

I am curious where you are running the wires through the firewall? On my '92 I ran 10 gauge from the battery to a fuse block but I ran out of patience looking for an existing point to thread the wires through and just made a new hole. As an aside, having a properly grounded fuse block under the dash made adding gauges and extras so much easier. I have mine setup with a relay so it's only powered with key on--how are you wiring it in?

There's a big round hole on the firewall on the driver side that someone cut and already had wires running through, so I just keep using that same hole to run more.

I need to eventually block up the hole some, because mice were coming in from the engine bay in early summer. I finally got rid of them all after a couple months of setting snap traps and finally putting in a few mice repellent mothballs in the engine bay.

I'm tying in to an existing addon battery isolator solenoid that actives via ignition switch. The hole isn't far from it.

Did you put a test light on it to check if it's hot?

no, I had the batteries already unhooked right now when I noticed it
