I've got a pretty whacky gremlin thieving my speedometer signal to my dash cluster. I'm looking for any diagrams anyone had for speedometer wiring specifically for manual transmissions.
Year?
1988-1990.5 went from the speedometer sensor in the tailshaft housing to the bulkhead connector near the master cylinder to the speedometer and then to the ECM. If that's your year range, it's worth checking the fuse panel inside the cab. I had an '88 which had corrosion in the fuse socket which supplied power to the speedo.
Year was in the title of the post. I've been through about the entire thing. speed sensor, connector, wires to the firewall, dash cluster, and drac module
