The ground circuit is different between the two connectors, circuit 359
Oh crap, there is multiple circuit 359's too. lol.
98 wiring diagram
Found the later one in the definitive pats thread but I need the description of each pin so I can make sure my Frankenstein connector will work before I chomp the c116 plug off the perfectly good 96/97 motor harness
I cant find it, im about ready to scrap this thing
Well with scrap prices down I'll offer you tree fitty for it lol. But for real, if you pull the upper intake off you can remove the entire harness and start checking that engine to trans plug. I would pull it out and start with the basics, check for wire colors matching pin to pin and go from there.
Im trying to find the pinouts with description so i can just make a harness out of two extra plugs to go between the tranny harness and motor harness, really dont want to take anything apart, im in a real bad way right now and need this thing on the road, my wife left me ,took my kids moved ten hours away with some dude she has been keeping on the side, took the mountaineer the green xlt is in her name, oh and she hasn't paid any bills for months and left the bank account overdrawn, so im pretty f...d up rite now and really need help
Dude, I am sorry to hear about all that!
Keep your head up, It will be a hard time but you will get through this.
I don't think there are pin outs in Fords stuff for these connectors. We have to follow the wires from the PCM to the trans connector and figure them out ourselves. I will try to help as best I can but am under some work related stress myself.
It seems like the pins 64 and 91 were the circuits used, the transmission range selector is a stepped resister so it just changes a voltage going back to the PCM.
You are sure you have an 8 pin connector at the TRS right?
You then ran a jumper wire from pin 64 to the TRS. Did you separate the wire that was already there? it may be going to another place as well and be throwing off the voltage reading. I will look over the diagrams and connectors I posted. Can you at least tell us what harnesses are from what vehicles?
So PCM is 1997 5.0 explorer
TRS is 8 pin from 1997?
PCM harness is from ?
Trans harness is from ?
That sucks man, keep your head up and stay strong. Life has its ups and downs, it can only get better going forward.
The pcm and engine harness are from an Mountaineer with a build date of 3/97 (I sold them to him from a part out truck).
Hey guys thanks, the motor harness and pcm are late 97 like boomin said, the tranny and its harness are early 8pin trs 96/97 , I have my brothers late 97 xlt here and i dont know why I didn't look at his before I put this tranny in, but yea his has the later 98 up style ,
What do you think about my idea of using the two extra plugs I have to make a jumper harness, I have the right ends to do it just need to figure out what wires to connect from one to the other
I understand your frustration with this. I used an early 97 motor harness with a 2000 tranny and had nothing but trouble. I finally just went to the junk yard and found an early 97 Transmission harness and it solved all of my problems so far.
Good luck, if you need pictures of my harnesses let me know. I took a few to compare when I went to the Junk Yard.
when i put the stroker in my truck, i also used the 96 trans that was behind it (mines a 98) when i put power to the truck the od light was flashing and when i put the scan tool on it, the codes where a page long. i just repined my 98 harness to match the 96 trans.
Thats kinda what I wanna do, but with a short harness made from two extra plugs, at least I now know it will work ,thank you
How much did you have to change
Im sorry guys I know im asking alot, im sitting here just completely lost
Does this mean you have to use a 1998 wiring diagram? I don't see anything differentiating between late and early 1997 in the wiring diagrams.
1996 and 1997 are the same at C116 for circuits 199 and 359(there are 3 of these)
The late 97 with the xdt2 pcm seems to be a mix or in between model, my motor, pcm, and motor harness all match but I screwed up and put the 96/97 tranny and its harness in, I should have checked my brothers ( a late 97 xdt2 model) before I did this, his has the 98 and up tranny, or at least it has the twelve pin trs, I guess I should crawl under his an take a hard look at the other plugs and make sure as to what year version they are
Looking at the 1998 PCM and engine connector C116, and comparing it to the 1996 Trans connector C116
In theory you could repin the Trans connector side like this below.
Keep in mind it is only by looking at the circuit number and color, not all the wiring diagrams.
Use at your own risk.
Trans connector 1996
11 to 6
6 to 8
8 to 11
24 to 32
wire in 32 goes no where? ( it would have gone to speed sensor on transmission?)
7 to 9
9 to 15
15 to 7
18 to 14
19 to 24
20 to 25
22 to 35
23 to 38
25 to 33
(What is in 33 goes nowhere tape it up)
31 to 36
35 to 22
36 to 31
38 to 23
pretty much what 4pointslow posted. i think i had to add 2 power wires, and move 3 other wires.
You won't have to add the power wires, the 97 harness has the 3 already where as a 98 only has 1 power wire going to the soloniods.
Ok I just crawled under my brothers and his has a 12 pin TRS but has the white case connector, wtf ? The tag on the side is pkf-af with a 97 part number, and the one on mine is pkf-ad1 with a 96 part number but it came out of a 97 ,
yea, thats what i had to do. mines a 98. the 96 trans needs power in 3 different places, and 98 had one.
Still trying to get this sorted, I have posted in the wanted section looking for a tranny harness from a late 97 with the xdt2 pcm and the pkf-af tranny with twelve pin trs and he early white case connector
I just finished my previous post that you could use if you wanted to repin the 97Trans harness to the 98 PCM harness. If you get a new harness instead then you wont need it I guess.
