Default 4L60E Trans wiring

I'm clipping transmission wires & getting this 4L60E pigtail ready to be soldered when I noticed that I'm missing the brown wire that goes to the transmission connector (Pin "U"). I I have about 12" of the brown wire on the pigtail but I need help finding out where it goes from there. I have been searching & cant find anything! Here are a couple pictures below.

Was actually working on my transmission connector today. My harness is originally setup for 4l80e and I now have to change it to 4l60e.

4l80e 11 wires
4l60e 13 wires

if I'm not mistaken

Spent few hours googling pinouts. After looking at pin outs and matching circuit #'s on the list for a 99-02 harness on lt1swap to match pin# for pcm connectors I came up with this real quick.

Hope it helps. If all the info I gathered is correct this should be on point.

Not sure though why your pin M is black and mine is Gray. I have two 4l60e plugs here and both pin M's are gray.

You were correct. I found the wire sitting to the side. I must have threw it to the side by mistake when I was doing some other stuff with the wires but it was already tagged that it needed to go to the #2 pin position on the red connector. Thanks for the reply!

I have 2 4L60E plugs & the wire pin at "M" is black on both. I think it all comes down to where the sensor ground is coming fromClick the image to open in full size.. Good looking on that diagram. I wish I would have found that the hour I was searching before I made this thread. I'm going to save that in case I need it on the next build.

Oh ok. That diagram helps a lot as far as finding out which pin/PCM the wire goes to without having to pull up the schematics & all that other stuff

Yes I'm going to use the safety switch. I was told that I only needed to use the 4 wires from the bottom plug since I plan on using the starter crank & reverse lights from my cars wiring instead of the upper connector on the switch. Can you confirm that this is true?

Honestly have no idea, if that is true that would be great and save me the headache.

I have a 2004 5.3l
Harness that came with it was all cut up and missing majority of it.
It had a beat up neutral switch zip tied to the engine with the larger connector sticking out of it with these wires

Pin D has blk/wht wire
Pin C has pink wire
Pin B has light green wire
Pin A is not used

Pin G has drk green wire
Pin F has gray wire
Pin E has pink wire

I ended up buying a 99-02 harness and the larger connector for the neutral switch was cut off and missing. The wires left over were

PRND pin# 62 to red PCM connector its a gray wire

PRND pin# 34 to blue PCM connector its a white wire

PRND pin# 32 to blue PCM connector its a blk/wht wire

PRND pin# 72 to blue PCM connector its a yellow wire

And that's all I got.

I bought a new pig tail that's supposed to be for the neutral switch(the bigger connector)

Pin D is black wire
Pin C is brown wire
Pin B is orange wire
Pin A is white wire

Pin G is yellow wire
Pin F is green wire
Pin E is purple wire

Do you have all your wires labeled on yours cause I'm at a lost.

If you really can ditch that connector it will help me out big fking time lol.
