    speedo wire pinout from 90-91 blazer/burb

    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.

    look at the traces on the board and see where it goes to in reference to the connector plug/wire. I can't find my info right now, best i can do

    i traced the circuit board and it looks to be pinout #18 LT BLU/ BLK, but im not sure. thanks for the help. one more question on my 82 connector plug it has 3 black wires and on the newer cluster plug it only has 1 black wire, iknow you said just to color match but what did you do wi the extra wires?

    I know I have a couple that just don't go into new connector. When I did mine I had a schematic of both connectors, but If you match your wires to new connector you should be fine.

    what did you do with the wires that didnt connect to the new connector?
