[Need help ID'ing this cable/connector]

With electrical parts knowing that is was working when it was pulled and/or dealing with a reliable seller is the safer bet. Sensors can get trashed. E30 ABS module in the earlier models had an external relay under the dash. The relay has a fusable link inside that can get shorted out but easy to replace, some folks replace by resoldering the link or replacing the relay with an inline fuse. So if you have a module issue check the relay first.  Later model e30s (1989-on) don't have that external relay and instead have an internal relay in the ABS pump unit under the plastic cover.   https://www.r3vlimited.com/board/showthread.php?t=107828

Thanks! That's a great reference.

yep that's the other piece. You should have an ABS light showing in your cluster unless the PO removed it, taped over it.

Any idea if the ABS sensor module is worth it to buy used? Not sure if that's a part where wear is a big issue.

Nice plastic slag. ABS sensor wire routes into the wheel well. PO disconnected it and left it next to the exhaust header?

Most likely. Would it have plugged into this connector?

While replacing my passenger side headlamp bulb (swapped in some 9012s [emoji16]), I found this cable hanging loose in the engine bay. It routes in through a small hole in the wheel well, right below the ignition coil (see second pic). The connector is completely trashed, looks like it melted.

Is this a connector for the OBC? Or something else?
