I recently purchased a '64 C60 with 292, SM420, Hydrovac brakes, and two-speed rear axle. I'd really like to get the speedometer working. I have searched for information to no avail.
The speedometer cable routes as follows: Speedometer to small aluminum looking piece (inside firewall between pedals) out the cab to the transmission. The small aluminum piece has a wire terminal with no wire connected to it. I assume this is to work in conjunction with the two speed rear axle so when shifted the speed will read correctly.
Does anyone have a wiring diagram for this small unit? It looks to be original GM and bolted the firewall
