1985 Cruise Control Module
As background, when I purchased my rig in June, 2022, the speedometer was not working at all and the owner also informed me that the cruise control worked "intermittently."
Checked the speedo cable and it was faulty. Replacement cable got the speedo working tho it bounced quite a bit.
In the process, discovered the speed control output was faulty and replaced that as well. The cruise control then worked without problem.
After the above repairs, went on an ~500 mile round trip during which the speedo failed. Cable still turns so appears the problem is the speedo itself.
Purchased a reconditioned instrument cluster which has an "RSS sensor" wire from the speedometer that is not present on the OEM unit. The cruise is working without the RSS sensor.
So here is my technical question: If I can find the cruise control module, I think I can confirm that it is indeed connected directly to the speed sensor without going through the speedometer. But I do not know the location of the cruise control module. Can anyone enlighten me?
TY in advance for your time and expertise.
