Installing a 90s floor shift and console into my 03 ext. a that originally had 60/40. There is no hidden harness to be a direct plug in. I’ve been reading for hours and googling to see what all the wires do in the plug. The question had been asked a few times with answers being guesses that didn’t work or no answer at all.
surely someone know after all these years of this swap being done. I have these colors
pink- ?
dark green and white -
gray- dash lights
yellow-?
light green/ black- interlock How to hook up so it works correctly. Don’t want it clicking every time brakes are hit or
Engaged all The time truck is running
black - ground
Where do the questioned wires need to hook to? where or how does the interlock wire need hooked up to work like oem.
please No guesses. I’ve read them for hours

Have you checked up on the firewall by the hump for a harness? It should have a plug with a jumper on it. The trucks didn't floor shifters until '97, so that harness is not there. It should be on '97+ trucks and Blazers even if they have column shifters.
Somewhere in this thread and embedded links, should be all of the answers to your questions.

This is strictly a guess, but would make sense. The SUV's had the harness tucked behind the carpet on the hump if they had a column shifter. It would make sense that the trucks starting in '97 had the same harness if they had column shifters. Floor shifters did not come in the trucks until '97.

Something to note though. I have an 01 2 door blazer also. I just went out and looked for that plug. Yep
Plain as day to right of gas pedal. Didn’t even have to look for it. That being sad. It is defiantly not in the truck.

Well....so much for common sense on GM's part. There is a list of what wires do what in that link. I just don't have the time to find it. That's what I used when I did my conversion. The only one I had a problem with was the yellow wire. That one prevents taking the key out unless in park. I lived with it for years until we did the LS swap. Since the dash was out, it was the perfect time to get a column from a truck that had the floor shift...plug and play. It came out of a '97.

If I were you, I'd get an '03 column with a floor shift and swap them out. It was only $25 at Pick N Pull. I swapped the ignition cylinder so that I would still only have 1 key.

If I can get a few minutes I'll take another look. Honestly, I wish I had done the column swap years ago. It's very easy.
