I recently picked up an 88 c1500 and I've been trying to figure out why the speedo isn't working. After looking around here, I found a couple instances where people mention that the Turbo 400 tranny doesn't have a VSS that is needed to run the stock speedo. One of the PO swapped in the Turbo 400, but I'm not sure what may or may not have been done to convert the speedo system. When I was under the truck looking at the driveshaft, I noticed what looked like an orange wire that was broken toward the rear of the tranny. I assumed that this was something to do with the VSS, but now I have no idea what that wire is for.
So here are my questions:
Any idea what that wire at the rear of the tranny on the driver's side?
Is it true that the Turbo 400 is not normally compatible with my stock electronic speedo setup?
What options do I have to get my speedo to work? Manual to electronic converter, etc?
Thanks.
