1964 c20 292 3OTT upgrading to OD - need education please

[Gianyveedub]

Having the governor tied to the ground of the relay allowed me to drive the truck as I would, if I forgot to turn off the OD when slowing down, it would automatically unground to relay and disengage the OD when below 28mph. This prevented me from accidentally trying to take off in 1OD or going into reverse in OD (will break the transmission). I did not have the original harness, so I had to come up with one that served the purpose I needed. If you are pretty savvy with wiring and relays, you could make your own that acts just like the factory one.

I wanted to as the saying goes, Keep It Simple Stupid.
