Let's see your FJ case swap

C10 Pins 15 and 16

 

Thats what I’m doing but it just don’t wanna work lol and I’ve tried shoving it in there many different ways (that’s what she said)

 

That’s because you’re in the wrong pins, if I’m seeing that correctly.

 

If you rotate the diagram to match how you’re holding the plug, the two pins are in the upper left.

 

Sonofabitch I’m a moron you right I have it backwards. I hope I can fix it now lol

 

I may be wrong. I just realized that the pinout diagram may be looking at the plug from the front, in which case you’re correct. Just start shoving wires into the empty holes and see what happens.

 

I have read many a wiring diagram upside down and backward scratching my saying WTF!?

If your lights start working at the end of this, I call it a win.

 

No he has it right, the plug diagram is looking "into the plug", so you have to flip it upside down and do a 180. Hard to visualize but they are correct.

 

Pin 11 is green which is for brake warning and Pin 12 is pink which is for high beams which match up to his plug

 

Yeah I realized that after I commented, thinking I was so damn smart lol

 

did you wire the correctly at the t-case? You'll need the two wires you ran to the cluster to go to each of the detent switches. The other wire on the detent switches need to be wired to a good ground. And also, did you put the detent switches in the right spot on the case? There is also a neutral sensor which should stay plugged.

 

For your setup the white wire should go to switch No. 3 (passenger side) and the blue wire should go to switch No 2 (drivers side front switch port). Switch 1 should be capped.

 

I remember taking my time and referencing that wiring diagram when I set it up, confident that it’s correct at the transfer case. So if my wires are in the correct holes, then I need to get a good ground and try bigger gauge wire. If that don’t work then I will give up

 

From the pic, I honestly just dont think those wires are making a good connection to the pins on the back of the gauge cluster through the connector.

I cant tell from the photo but they look like they are pushed through the back of the plastic connector without a crimped metal contact on the pins that seats properly. Might be making the connection...might not. Still just trying to throw out possible issues. Looks like you've done it all right.

 

Yep those are the wrong pins, also the leads coming off the tcase have to be right as well

 

They are correct, all the colors line up with the other pin numbers, he is holding the plug looking opposite from the drawing pinout reference.

 

this is what I did here.

 

When I wired my 4wd and 4lo lights during my 2wd to 4wd conversion, I was able to source the terminals for the cluster connector.

I should have a few spare terminals if needed.

 

Lol bare wire works just fine for me. Never had an issue yet….
