5.2 swap questions

After watching a few videos on all this.
I think I'll merge V8 stuff into the TJ harness.

So I just leave the C103 & C104 alone.

Does that sound about right?

There are still wires that have to be spliced or added... But it's been too long now for me to remember... And I sold my Magnum harness a couple of months ago to another forum member so can't go look at it.

Seen this, but I'm using a ZJ engine harness, and a TJ firewall harness and a RAM ECU

And in that list what doesn't match up between the GC & Ram plugs?

So far RAM to ZJ not much other than a RAM don't have the C131 & C132 plugs
 
Well after my lovely Wife showed me "Co-Pilot AI - We asked it to break down the 4 plugs I was having issues with. And now I'm really questing the info I had..

Found the AI was basically what I already had. Mild differences but ones that look more like "Options" than requirements.

Wish I could be of more help on this....

This is one of the reasons it's suggested to use a Ram harness also since there isn't as much in it compared to a GC or Durango.

I am sorry, my nights have been busy. I will gather what I can and post it.

it would be neat if you could put all the information into AI and then it tell you what wires to blend.?

C104 has me confused. All write ups on it I have are 10 PIN including FSM but the plug has 14 wire locations..
IF I go by color I have them but in wrong spots,,,
 
Found that in 00' Jeep started using the 14 pin C104 but only had a call out for 10 pin use. I think it was a late mode year thing. BUT 1-10 are all same colors and items, it just has more pins.

@Wildman
do you have a more detailed write up of the following?
Looks to be my last step

You need to add a pin to Pin # 13 on your C3 plug. Run the wire through a relay and connect the other end to ground. Then connect a momentary switch to the coil of the relay. To turn OD off hit the switch & to turn it back on hit the switch again. The OD controller wants to see ground momentarily to turn it on & off.

No that is about as detailed as I've got..

Technically you don't have to use a relay either. You just need a momentary switch. You're grounding the signal to the O/D solenoid inside the transmission.
It's just a quick connection to a ground that disengages or engages the ground.

I did add a light also on my 46RE.....
