I replaced the TH700R4 in my 89 C1500 with a 4L60E and a Painless Torc transmission controller. Everything is working except, I have no idea how to hook up the speedo. The controller has an output signal (1 wire) but how do I connect it to the speedo?
Anyone got an idea how I can have the original speedo working?
thank you
