I should have mentioned: Built at San Jose.
This car has a single, square, black connector. Wires are: light blue/red tracer, black/red tracer, red/blue tracer, red/blue tracer. Makes sense as two of those are for the reverse lights.
I did a search and under the C4 trans. there were photos of the twin split two connector safety switch/reverse light connector. My concern is mainly the trans mounting issue if any.
