What is the purpose of the connector that is down near the tail shaft of the the transmission on my son's 89 camaro rs. His 92 camaro has a place where the two prong connects up to. I think maybe the transmission was changed because 2 tranny mount bolts were missing. I'm sure his lockup works.

 

Most likely for the VSS, vehicle speed sensor. Earlier cars had a cable driven speedometer.
