Troubleshooting a lack of VSS signal to the ecm on my 87 grand national, I found a lack of continuity on the brown wire from the speed sensor buffer (green box) to pin A10 of the ecm. Turn out the wire runs through a connector that is about 14" from the ecm, and is buried behind the passenger kick panel. I found the male terminal on the VSS wire was completely bent over and not making contact. But here's the thing, the foam wrapped around the connector was 100% unopened and appeared original 
Could this car have had a CEL code it's whole life? No lock up torque converter ever?
The speedometer does have markings on it that it was serviced in 1991, were they chasing the problem but didn't know how to fix it?
