A few weeks ago the heater core went out on my 5-speed 91 LX. Towards the end of putting everything together, I noticed that I had one leftover black connector that seems to be coming from the instrument cluster harness. I just assumed it was extra or not needed because the car is already a wiring nightmare since the previous owner bypassed the NGS and the clutch pedal safety switch and there were no other connectors left to plug it into. Once it was all back together I noticed I was getting an airbag code 4 which is supposed to be the safing sensor but I am at a total loss as to where this connector goes or if this connector is just a coincidence and has nothing to do with this at all.
