HiCustomer Welcome to JA. I am Buddy, and i will try and help you out.
What is your engine serial number and also the last 6 of your truck vin # ?
Thanks for the info.
The vehicle speed sensor wires are at pin location 12 and 18 of the vehicle harness at your ecm. Here is also a diagram. DIAGRAM <<<<<< click there for wiring diagram and go to page 2.
I hope this helps you out. If you have 2 sensors or 1 four wire sensor, then 2 are going to the ecm and the other 2 are going to the speedo. If you just have 1 two sensor, then the ecm gets the vehicle signal and then sends it the speedo head. If you have anymore questions, just ask.
