I'm trying to interface the cruise control switch from a 94 S10 column with the harness of a 2004 Silverado 5.3, 4L60 and modified factory harness/PCM. Can't figure the schematics. I have studied the 04 schematics and can't find where to splice in. Also need the wires for the 94. My Alldata subscription ran out.

I can only find it on the 4.3 wiring diagrams

You don't need any pcm wires. You need three wires from the TAC module to activate your cruise.

Thanks, that makes sense

According to the diagram there are 3 wires that are labeled cruise. D Blue, Grey Blk, grey. They run from the TAC to the PCM. I still need to know what to connect the switch to. That is the mystery.
I have attached the appropriate diagrams for the TAC.

Does anyone have the diagram for the 94 s10 column?
