The wiring should be all the same, at least I haven't found any schematics or seen any cars where it was different. If you can post back the wire colors I can verify it for you.

Hi all,
I am hoping to have time in the next few days to replace the dashboard.
I decided to go ahead and reinforce weak points in the dashboard before reinstalling.
In close observation I did find cracks in the dash.
The method I used to fix and reinforce was a three stage process.
First, I applied crazy glue in the cracks to seep through cracks to the vynil beneath, for preshaping and holding the parts together for the next step.
Next I covered the area with epoxy glue all around the cracks and weak points that might fail in time.
Finally, two areas got special attention:
The dash mounts: I got special plastic epoxy putty and applied it all around dash mounts for reinforcement.
The tabs which hold the panel in drivers side where completely disintegrated: After applying crazy glue and epoxy I inserted the three metal tabs for screws. Then I took a piece of metal wire (clothes hanger). I shaped it to the contour of the dash and placed it through three metal tabs and glued it all together with epoxy putty.

Here are some photos of the process. First the cracks and the broken parts, and then how I went about to fix it.

Good morning.
The top of the dashboard could not strengthen and repair cracks with epoxy, because the glue just did not connect with this plastic type.
In this part I used a different method: I fused the plastic cracks, with a soldering iron.
I think it's strong enough to hold a few more years.

Hello everyone.
Today I finally found the time to dismantle the dashboard of my car.
I was horrified to discover the passenger side air bag was assembled dangerously with most screws are missing, and those that are, are not the correct screws.

After I dismantled everything and took out the wire harness. It bothered me that its all sticky threads. and with crumbling Sponge.
I decided that before I reuse the wire harness, to rewra the harness, so it would be nice to work with, and pleasing to the eyes.
Was a bit hard to find back to the original location of thewire harness. Lucky I photographed before I dismantled so that it was easier to arrange the wire harness in place.
