I have a 1967 Barracuda 4-speed car. The wiring for the reverse lights on my car run from the same bulkhead connector that the wipers are on. Standing in front of the car looking at the firewall, it is the farthest one to the left. There are two violet wires that come out of the connector. They run down over the top of the bellhousing (there is a metal clip attached to one of the engine to bellhousing bolts) and fit into three little "clips" that are attached to the transmission side cover bolts. They terminate at the reverse light switch near the bottom rear of the transmission gear case. The connector at the end of the two violet wires has two female spade receptacles that plug into the two male spade lugs on the reverse light switch. I'll see if I can find some pictures tonight.
