God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Help identify a wire

Hey guys I'm replacing my timing belt and I've noticed a broken wire. There's a thin brown wire wrapped up with my crankshaft sensor wire. The end close to the crank sensor is snipped and the other end goes under the intake manifold to somewhere. I'm assuming it's a ground wire but not sure. Anyone know?

You can see the brown wire along the crank sensor wire. The end close to the crank is cut and the other end disappears under the intake.

The wire from the oil pressure warning switch runs from the right side of the block into the engine harness via the front of the engine along with the crank position sensor wire.
It is probably hard and brittle.
There are no other factory wires in that area.

Thanks, I'll verify it's not that although the oil light isn't on so I don't think so. I'll probably just snip it and get it out of the way.

From that wire in the picture you posted, it looks like the Engine Reference Sensor wire and do yourself a favor and re-route it up and over the Engine.

This is what I did, and I have nothing behind that area any longer!

As mentioned above it ended up being the oil pressure switch wire. I found the other half going under the ac compressor area. I repaired the wire and tied it back out of the way.
