84 and 91 C100 Differences?

Hi,

I'm swapping the dash out of my 84, and installing a 90-92. I'm to the point where the only thing holding that dash in the car is that huge connector that goes to the firewall.

How do these come apart?

My Next question is, does anyone have the pinouts for a 84 and also that of a 91? I want to see what's different and needs to be changed to make this dash work.

Thanks
Chris.

Anyone?

I hope someone has a diagram of each.

I'm hoping to work on this more today, and trying to figure this piece out.

I got the harness apart, didn't see the screw that holds the 2 together.
But still looking for a diagram of what all the pins are for each year.

Anyone have them?

Does anyone have the C-100 diagram for an 84 and 91?

I've been searching the forum, and found one for an 87, but not sure how close that would be.

If anyone has a diagram like the one attached, for both a 84 and 91 could you please share

I want to start my dash swap, and having this would really make things easier.

Thanks
Chris.

I'm hoping to be able to instead of cutting wires at the back of the dash to just move the pins and match them up to what my current dash uses.

I really hope someone has these!

Somebody has to have these?

I was hoping the chiltons book I bought would have this, but I can't seem to find it. On one of the figures it says for C-100 see page 8a-12, but there is no such thing.

I really need these diagrams. I'm hoping to cut as few wires as possible when doing this swap, and having these for both years will really help.

Does anyone at least have a 90-92 diagram, that I could at least try and compare to the 85 one I found?

Maybe I can at least find if any of the wires are the same between those 2 years.

I'm looking for the 1984 but it's NOT easy to come by.

Thanks!!

I have a feeling the 84 will be a tough one to find, and I'll have to just hope this 85 one is the same.

So far, most of the pins are matching up.
