Thanks for posting

Thanks for your complement. A normal LS swap isn't that complicated. I'm just a glutton for punishment by trying to bring the rest of the harness along for additional features. This creates a lot more work and complications.

Thank you for sharing! It's been slow going lately, but I hope to get things going again.

I know it's going to be tight. The center console should help. I don't think I could pull this off w/o that. We will see. Thanks for your comments.

I was thinking of this last week. I need to figure something out. I appreciate the link. I will take a look at them. Do you have a picture somewhere of where/how you mounted it?

Slow weekend trying to get my head around the main cabin harness. I started by hooking it into the main fuss/relay box under the center console. The challenge outside of the bulk of wiring, was to hide three components - the mid junction box, the cabin remote fuse box, and the body control module (BCM) under the dash and with close enough proximity to not have to cut and extend a bunch of wires. Here are some pictures of the starting point.

For the mid junction box, I need to fab a mounting bracket to attach to the center console under the HVAC unit. I don't have the final picture of the bracket. I basically made to identical sides shown below then welded on a bottom and a wire brace in the back to keep it from being flimsy. I will be able to mount the box to the center console and then connect and remove the various sub-harnesses. The bottom pins slide in and down, then the top snaps into the square holes. To remove, you push the release tabs then pull out and up. Here are some pics.

I still have to make a similar bracket for the remote fuse block and BCM module. The BCM will mount on the factory steering wheel brace between the cowl and dash. I don't have a picture of that yet as it's just zip tied and the moment. The mini fuse block will go to the left of the steering column.

I still have a sub-harness that will run down the center console that is for the seats and the passenger door controls. I also need to put the steering harness on the column. It's small. Those are pictured below.

I also have a small harness that runs from the junction block in the console to the rearview mirror for the compass and outside temp readings. No picture of that yet. I will run it up inside the passenger A-pillar.

Last post until the Christmas break.

Here are a few pics to see a cabin view of how things are progressing. I hope to have things hooked up and tested over the holiday break. If I can do that, I will start the process of cutting and extending the window and door lock controls since I will have those mounted in the console.

Thanks for looking.

By disconnecting some components of the original harness, will that cause problems with the canbus monitoring?

Not that I've been able to tell so far. Earlier last year, when I removed the airbags, stability control, ABS, and a number of other items, I hooked it all back up on my pool table and everything seemed to work. The instrument cluster complained about the ABS and Airbags, but everything else left was working. I pulled codes and nothing out of the norm (for my situation) showed up. Granted, I wasn't able to fire it up, but I don't think it will affect the ECM. The cluster is looking for them, put I don't think it has the ability to disable anything. There are many cars on the road today with issues around airbags, ABS, etc and they run just fine.

When I get to the tuning with the HP Tuner, I will see if it has capability to suppress canbus codes. I don't think it can, but I'm not familar with it yet. As long has the bus codes don't hobble anything or turn the CEL on, I will be happy.

I did take the time to find the termination plug at the end of the bus and placed it at the last in line after the Fuel control module to correctly terminate the bus. In my system, I removed the integrated trailer brack controller (ITBC) so I had to move it up on the chassis harness.

The picture below shows the HS canbus network (middle one). The complete harness now goes from ECM, TCM, BCM, MBEC (the big thing under the console), FSCM (fuel pump module) and Termination. Everything else that I'm transplanting is on the low-speed network. One other note - from what I understand, you only need to have the ECM, TCM and BCM for cruise control to function properly on a Gen IV swap. Since I was going that far, I kept the MBEC and FSCM since the MBEC has all of the relays and fuses.
