Power Column pin-out wiring help
I am looking to add a tele C7 column to an older Vette - does anyone have the pin outs on the circuits required to be powered to get the two motors to move when the up down or fore-aft button is moved?
I expect the current switching is inside the small black module screwed to the column - I can apply current direct to gray or yellow wire and switching the probes get the up down to move, but nothing happens when power applied to what appear as the larger pins that appear as the input connector.

we'll somehow my post from a few days ago never made it here or it got evaporated...
The module you reference is on the column, I had procured salvage wire for the idea of key connector simplicity but that section I think was cut off.
What I was able to do the other day with the power supply was get the up down motor to run and by switching the +/- get the motor to run the other way, I was not able to get the fore aft to run, and that may be due to a damaged motor - not sure just yet.
today a bit of good news in that I have a clean IP harness and all turn and wipers etc are now connected properly which means that either I go back to the idea of partial C7 harness for the key features I wanted to power, lights High Low turns parks, and wipers. IN the center stack I had already cleaned up the power up screen from a 2012-3 Cadillac, adding all those modules versus a smaller aftermarket touch screen and connectivity solution - not sure I want to get into that space.
Next is to get the body harness which I think has the battery power at the rear and see if I can then get this running.
I know the ford's have a full wiring schematic connector to connector, module to module, book at a very accessible price, does anyone know if GM has this?

AllDataDIY.com has most of the schematics and the connector pinouts. If you want it straight from GM, you can get a 3 day pass to their system for $20 at ACDelcoTDS.com.
There's also a PDF service manual of questionable origins on eBay for next to nothing. I haven't found any errors in it so far.
