V1 Harness Questions

[averageJOEschmo]

I have a 2006 2.4L SS/NA Auto Donor and I'm currently working through the wiring harness and have a few questions that I couldn't find on the forum:

Question #1
In the Part 2 video it shows the EBCM connector wiring that is a little different than mine as I have ABS and I'm unsure of some of the wires I need to keep. I thinned the ones I was sure of but I'm at a loss for the remaining ones pictured below:

#1 is a large red w/ black stripe wire that connects to position B1 on the smaller rectangular light gray multi-plug in the main fuse box.
#2 is a pink wire that connects to position B2 on the dark gray square multi plug in the main fuse box (i believe this can be used to power the intercooler which i don't need).
#3 is a gray (or maybe light blue) wire that connects to position F4 on the gray multi-plug then to position 7 on the ECM connector.
#6 and 7 are tan and tan w/ black stripe twisted wires that connect to position C5 & C6 on the Dash connector.
#4 and 5 are tan and tan w/ black stripe twisted wires that connect to a connector I do not know:

This connector has 4 wires that i am also not sure what to do with:
The tan and tan w/ black stripe twisted wires from the EBCM connector.
A brown wire that connects to position B5 on the red BCM multi-plug then to position 18 on the ECM connector.
A green wire that seems to be the back-up lamp wire

In the part 2 video at 1:38 - I don't have the tan and brown twisted wires
In the part 2 video at 1:48 - I don't think I have a vacuum sensor connector

Question #2:
In the Part 3 video, it discusses the fuel pump wires. I know I need to keep the Large Gray (C), Tan (H), and Purple (D) wires for the fuel pump. I would like to keep the evap system wires as I may need them to get registered. I just don't know which ones they are:

Question #3:
After going through parts 1, 2, and 3, I'm not sure if I should be keeping or thinning the extra seat connectors and wires:

If you thin them out, how do you keep the seatbelt warning from always going?

Thanks for your help!

I have a 2008 2.4L auto so our wiring should be pretty similar. I have to say I do not remember that connector for the EBCM even though I also had ABS.

A few things that helped me out was the original wiring videos. they are for a 2010 2.2L auto so there are more similarities. Note: the new videos do not tell you to extend the auto shifter wires 20" but the old ones do. The link starts with video 9 and you can read through the old videos as well as the questions for help.

Another thing that helped a lot was a great pin out chart and tables done by a former forum member:

V1 - BAR-AIR's build up in Buffalo N.Y.

Yes those are 5 3/4” lenses. Just make sure they are the DOT lenses. Those were advertised as DOT lenses but when they showed up no DOT markings. Took about a month of back and forth with the manufacturer before they sent a set of DOT lenses. Nate’s car is using a set of 5 3/4” headlight shells...

It helps to cross check what you are working on.

For the twisted pair: you can follow this thread. basically, as you remove components, you need to reconnect the wires to keep the loop. I had to think about it a lot as I had a high option auto sedan which was different than the coup manual cars that are more commonly worked on so our twisted pair has a more convoluted route. one option is to reconnect the loop every time you cut it out of a connector and then shrink the loop to fit at the end or follow the videos (old and new) and trim as you go and extend as needed at the end. I used this picture as a confirmation of my plan and it all worked out.

High speed GMLAn

on my X101 Body Harness to Engine Harness, I cut out the high speed GMLAN serial data wires during the main harness thinning videos. Is this correct or do we need them? It is the purple 14 pin connector.

As for seatbelt, yes, you will get the instrument panel warning light. Most people leave it on, some people block out the light, maybe someone can fool it by keeping the wire to complete the circuit as if the belts were plugged in.

Good luck.

I think there quite of bit of difference between the pre and post 2008 models. Especially on the data wire routing and colors.

Thanks Joe, the info you provided helped me answer the 2nd and 3rd questions but I think Gtstorey is right that my wiring is a little different than yours.

The old harness video (Part 10) @ 15:52 shows the twisted wires coming from the XM radio being removed from the dash connector.

And then @ 16:14 it shows it being saved at the purple and black connector

I don't have XM in my donor but the it looks like i have similar connections coming from my EBCM, am i safe to assume i can do similar?
