4x4 wiring plug doesn’t exist
Can someone tell me where the plug wiring for the 4x4 switch, wires to in the 1997 Chevy blazer? I have the transfer case, the switch and the driveshaft going from the transfer case to the front and back axles but no lights on the switch and no engagement to 4x4 and upon further inspection I found out I don’t have the plug at all and after inspecting grounds and power wiring I haven’t found the wiring for it like the videos stating so I may just re-wire a plug for the 3 button switch from Amazon but need a working digraph to find out where to go to start that kind of job IF I can’t find the plug already in the blazer :/
I have the three button, (7 pin plug), switch so I have 2hi, 4low, and 4hi
help!?

Has this Blazer been modified?
It's not clear what you mean by: " I have the transfer case, the switch and the driveshaft going from the transfer case to the front and back axles but no lights on the switch and no engagement to 4x4..."
Are you modifying a 2WD to a 4WD?
Would be very uncommon not to have the respective connector (plug) for the switch just behind it in the dash.

So, just to make sure we have properly understood your problem:
Not sure how the 97's controlled the transfer case. Should there be a separate TCCM?
How does the vacuum actuation look?
Try having a look at rockauto's literature for that model. Sometimes you can get by the original factory manuals on DVD. But not the HAYNES or CHILTON. There are at least two manuals the service and the electrical & diagnostics.
Maybe somebody has the wiring diagrams for the 97 4x4?
- It used to be a 4x4
- Somebody has either removed or put a 2WD harness in as ProCycle suggested
- You have the proper fuse box
- The wiring from the fuse box to the switch is missing
- The wiring from the transfer case to the switch is missing

okay yes I did see when I was wiring my subwoofer in for the positive wire on the passenger side I did see that there was a ecu looking silver box there attached to the passenger side kick panel by the door so I’ll take a look and see maybe the harness was pulled back behind the glove box assembly too ? I’m not sure. Will update you on the situation once I get it apart again lol
