Fusebox UHBEC Connector Separation
I just went through this.
Use a 1/4" ratchet with 9/32 deep well socket. If you don't know which connector you want to take off, it is the one closest to the passenger quarter panel or B+ post on the side of the UHBEC.
Greg and I are putting together much better instructions. IF you cannot wait, PM me with email and I will send better pix than the instructions. It will be next weekend until I get this all put together.

Some much better pix
Guys,
Sorry I have been busy with my own install. With the help of Greg and belatedly, N2MB, I am done with the physical install. Not the programming.
Here are the pix I have taken. I plan on putting together a job aid with corrective editing N2MB has on their website for the 2004. Should be the same for 99-04.
It will take me until next weekend I am guessing to finish.

Pink Wires in Fusebox
This was a direct question to N2MB last night. When you cut A6 & E2, the "leads to the fusebox" are the short leads that are still attached to the fusebox. The "from" is the leads headed towards the ground/pavement.

These are great. I noticed you connected YELLOW wire to purple wire in pin 56. Are instructions wrong? it mentions C2-26..with red cover

[QUOTE=Efx;1594770699]Will update this thread with my progress. If anyone could confirm my wiring, that would be great... Also my box came with parameters set for srt4 dodge. Can anyone share their settings that work for c5z?
It may be a day or two till I have a chance but I can see if I can get a screenshot of mine and post it

Ok so instructions on the website are partially wrong...
Are these correct?:
WOTBOX Blue wire -> Dark green wire Accelerator pedal sensor (at the pedal)
WOTBOX Green wire -> Grey wire Clutch switch sensor (at clutch pedal)
WOTBOX Black wire - ground
WOTBOX RED wire -> A6/E2 pink wires going in to Fusebox (cut)
WOTBOX ORANGE wire -> pink wires going to coil packs (cut)
WOTBOX YELLOW wire -> PCM pin 26 with GREEN inside cover

You got it.
I highly recommend soldering even though it is a PITA.

That looks good to me.
Rich will be adding his notes and comments to this document when he gets time, but I'm going to post it now. Hopefully it will help clear things up.
Current revision is D
See post #35 for a wiring diagram I did. If anyone finds anything in either document that is incorrect, let me know and I will fix it.

Efx: Can you delete the Revision A pdf in post #30. I've added some information to make it easier to find C1-A6 and C1-E2 on the Under Hood Electrical Center.
This is still a work in progress.

Well Im in a pickle. I am not sure if I wired the yellow wire correct the first time or I am doing something wrong.
my c5z is 2003 and my PCM are red and blue.
Blue pcm pin 26 does not have purple wire
Red pcm pin 26 has purple wire where I connected the yellow one to.
Here the PCM with red connector with pin 26 purple wire
Here is 2nd PCM with blue connector, pin 26 is not purple wire
Here is overview of both PCMs unplugged
So confused

You did it correctly. C2 is the red connector. You do need to solder the purple wire that is dangling, to the purple and yellow wires if you haven't already done that.
I remember reading that they changed the connector color. Don't know what year that was.
I'll see if I can find it.
Even if the color of the connector changed, the wiring diagram didn't.
From the N2MB instructions:
"For 1999-2004 vehicles, the PCM connector with the red inner cover is the C2 connector"
That may only be partially true. It may have changed from red to green in 2004. We need to look into this.
Update:
Found it. 2004 Blue and Green Connectors. 2003 Blue and Red Connectors
1999-2003 C1 is Blue, C2 is Red. I think they made some changes to the 2004 PCM and changed the C2 connector to Green

Yes I did solder the wires. Just took a pic prior to that for reference. Everything plugged in. Took 2 screenshots of the software for n2tmb to make sure everything wired up ok. Waiting for reply.
Will keep this thread updated with results.
Thanks again to everyone for their input. N2MB support has been outstanding btw.

Can someone who has actually installed one of these check this wiring diagram and let me know if there are any errors or omissions.
My skills with MS Paint are about nil.

With the help of this forum and Jon, i was able to wire and test the unit.
Everything works as it should. PM me if anyone needs more details about my install. I will post more pics of my wiring.

Need some help from you guys. I did my install this weekend: everything per instructions (and what I read here) except the trigger i tied into my brake light since im automatic.
The testing is NOT working out.
I ran the setup, downloaded new firmware, etc. I then did the first
"READ" and saw that the TPS V was at 4.10, so I inverted the signal and both showed "UP" on the vehicle snapshot.
Then I mash the accelerator to the floor, the voltage changes, but it still shows "UP"
I even adjusted the TPS Threshold (V) and it still never seemed to work.
Anyone have any screen shots of their WOT Box User Interface with their setup?

I'm not sure I can help you, but what wire did you splice into on the brake switch?
