Brake Warning Light & Loss of Fuel Injection

[nightshift]

Recently, I got stuck in my driveway with my `90 B2, 210k miles. After troubleshooting, I discovered my ignition and fuel pump were ok, relays ok, but the fuel injectors weren't operating, and I could get the fuel pump to operate only by bypassing at the diagnostic connector.

After more troubleshooting, I discovered a bad two-wire connector right next to the battery. Outside, it looked fine. Inside it was eaten up by battery acid. This connector carries the ground wire for the MCU (the computer), and the ground wire for the RABS. Coincidentally, my brake warning light had been up for a while, and I hadn't had the time to troubleshoot it. I replaced the connector with wiring (crimped, soldered, heat shrinked), and corrected the fuel injection problem and brake warning light.

I love happy endings.

De nada.

Sooner or later, this is going to happen to someone else here. Maybe this will save them some aggravation.
