4 speed NSS question

[Thealien]

I am replacing the engine wiring harness on my 4 X 4 four speed Blazer. I can see the reverse switch and wiring from under the Blazer and believe I can unplug the old harness and plug the new connector onto the switch without removing the transmission tunnel which I prefer not to do.

There feels like a wire clip fastened onto the transmission that those wires pass through. I can feel it but not see it. Is that clip a one-piece loop or something that I can bend enough to get the old wires out of and the new wires into? If I have to, I will just remove the wires from the bulkhead connector and pull them through and tie wrap the new wires to it until I remove the transmission tunnel someday.

So, I believe you are actually referring to the switch for the reverse lights. Here is a picture of the wire clip on an early 80’s truck. I am pretty sure they are the same.

You are correct, I'm doing that a lot lately.

That looks like what I can feel but not see.

Looks like I have to remove that bolt (do you know what size it is?) to remove and install the wires. If I am unable to get to that bolt, I will just pull the old wires out after depinning them from the bulkhead connector and tie wrap to that until I remove the transmission tunnel eventually.

Thank you.

3/8” bolt with a 9/16” head if I remember correctly.
