im swaping a 5.3L 4L60e in my 82 c10. in order to get my speedo to work i had to get a 90-91 burb cluster because its electronic and my 82 cluster is a cable driven speedo. im in the process of repining for the newer cluster, but im having trouble finding or figuring out which color or pinout # on the plug connector for the speedo. if anyone knows please let me know im having a hard time with the wiring.
