Are they the same as far as wiring and plug and play. 87 N/A. Turbo would be different I assume?
My clock is dead and looking for another, (has power, just won't illuminate) found a cheap one but it is for a 91.

Thanks all!

 

http://mazdatrix.com/in-dash.htm shows the angles of the front are different. they should all be plug and play but some have different lights

 

You can use the 91 model in your 87. You simply have to swap the covers on the front of them. Really simple to do.

I would suggest that if you are capable of solder things that you open up your current one and resolder every connection in it.

 

You sure about that?
I seem to remember that the clear plastic faces were not interchangeable and the displays were different, so repinning was necessary to make it work correctly.

 

+1. These are VERY simple to fix...

As in, I have ZERO customers for these. Every time I explain what's wrong via my troubleshooting PMs, people fix it themselves.

 

So some say will interchange some say not. Hmm. I have never soldered so I dunno if it would be something I could do. Is it actually simple enough for someone that has never soldered before, go out buy one and do it without screwing it up?

 

Not really.

Here's why:
Open up your display and everything is going to look fine.
There won't be any frayed/loose wires, the problem is the solder joints themselves.
You'll need to heat the suspect joints, use a vacuum device to suck out the old solder and redo the joints.

It's not that it's a difficult process but if you have zero soldering experience, chances are it won't turn out well.
