Question Pin 7 Mod, CDL & Lockers, HELP! (pics)

I just bought a 94 FZj80 from campoj2, its locked but not locking.
Please bear with me as I try to explain this right, Hopefully someone can make sense of all this and help me out.

He (campo) bought factory locked axles (he thinks they are from a 95) had them rebuilt by IPOR and then installed.
He put a CDL switch in
He said the owner before him did the Pin 7 mod (more on this to follow).
He put a new OEM harness to the front locker
The rear axle still needs a floor and sill harness (I think that's what he told me?)

From what I read the lockers won't work at all untill I get and hook up the rear locker harness....am I right??
Will not having the rear locker harness effect anything else??

I had a little bit of time this afternoon so I went out to fool around with the truck. I was not sure where to start on this but since the CDL is not working I figured I'd start there. From previous searching (i have Troubleshooting the Toyota FJ80 Land Cruiser Center Diff Lock (CDL) | Pacific Northwest Backroad Adventures and Slee - Pin 7 Mod for CDL (Toyota 80 Series Land Cruiser) and others saved in my favorites) I remembered reading something about 2 black & blue wires, (one being thicker than the other) so I checked that first.

Is this the right (7th pin) one???
The pic is not that great, its the thicker one of the two, 3rd from the left.



After reading Slee's write up on this I think that is the wrong wire (its kinda hard to tell from their pictures), so I pulled what I thought was the right one and replaced the other but still nothing lit up.
I then put all the wires back in and still nothing lit up.

I can hear the center diff lock relay 'click' when I push the CDL button on the 94, but on my 91 I hear a "hhmmmm" then 'click'. So then I swapped the transmission control relay from the 91 into the 94 but still nothing and all I hear is a 'click' no "hum" noise first.

I also started the truck and put it in low, nothing lit up but it was in low range for sure.
Also when I turn the key on I get 2 diff lock lights that light up for a few seconds, if I turn on the lockers with the key on those 2 lights blink. I know that normal but should I have a 3rd light for the CDL switch????????

For the Pin 7 mod, what wire is it....

3rd from the left OR 3rd from the right??????????





I think its the 3rd from the right, after I know FOR SURE then I can go from there.


Thanks for any help and feel free to offer and advice, comments, or suggestions.....I'm all ears.

Aaron
