Time for a new project!

So after working on this for a couple hours tonight, I realized how Holden put it all together on the line. What they must have done was to put the firewall in the cabin but not yet attach it to the bulkhead. They ran the harness through the hole in the firewall, THEN they bolted the firewall to the bulkhead. Either that, or the body harness was preinstalled in the firewall and everything came to the car as a unit.

The fuse block is physically capable of going through the hole with the bottom shell removed. But, the angle it has to make to get around the strut tower makes it impossible for it to go through the hole. So since I'm getting my firewall from a front clip, and it's already hacked, I'm going to cut the right side strut tower off, then I'll be able to push the fuse block through the firewall. Does this help the average guy trying to get his body harness out? No.

Wheres the PCM? Its on the passenger side in Australian vz (left hand side). I would have thought everything would be opposite? With the PCM on the passenger side US ( right side)?

I did my conversion a few years ago. Just looked it up. December 2015. So, 7 yrs. Don't remember pulling steering column or power booster & master cylinder. But l may have?

Thinking about it, probably would have had to removed the dash pad to remove the wiring loom? Can't remember, to long ago?

Our PCM is mounted on the left hand side as well (US Driver's side).

Since you have a bunch of pins, crimp skills etc, will it be less stressful to cut the harness and use a race connector in there so it’s all in two halves?

This type of thing. Might need two but off set would make reinstalling the harness way easy.

Part of the production managers job is to figure out the most efficient way of doing something. We studied this crap at uni but I've since forgotten it all. Needless to say it "flows" from one station/area to the next before you eventually get a finished product. Logically it makes more sense to add the component first, then the panel

I had to remove this as l was removing the standard hvac & installing climate control hvac & wiring harness for the climate control.

You pulled the wiring loom engine bay fuse relay box yet? If so, how did you go?


Here's a pic where l cut the fuse, relay box. l only cut the plastic.

So the BCM is on your passenger side right side US?

I'm trawling the factory manual and as usual finding loads such cool stuff buried in it. All the cool stuff except removal of the "Dash Panel Assembly"

The side of the Firewall/Dash Panel Assembly has that notch in it, so the harness has to be installed at the time of install of the firewall.

Ok.

There is a small grommet that is fitted to the side of where the harness goes through.

From here:

Of note is 24, and 25 above.

Probably the only video of the removal of a VT-VZ firewall.

From 3:30-4:30 is the nitty gritty.
I got this screen grab.
