Another Random Observation
If you happen to have a 76 Pacer with the one-year three-speed manual overdrive option, just remember there are TWO connectors on the driver's side of the transmission. One for the back-up light and one for third gear. They use the same connector.
Importantly the front one is the third gear switch for Overdrive. The back one is the reverse switch for back-up lights. It's the opposite of intutitive.
It's also important to note when you have to rebuild harnesses because the wire has rotted.
