I'd call these guys and ask them about your options - I can't recommend them highly enough:

For what it's worth, I'm not the only one who raves about them:

Today I got the battery tray cleaned up and repainted along with a good baking soda cleaning of the entire battery compartment. After I reinstalled the battery everything started back up except for the PCM.
I plugged in my Durametic and of course got a lot of codes relating to the PCM. There were no faults found in the Motronic DME module.
So I'll head to the dealer soon, and if the PCM is truly fried I'll check out Becker Auto Sound or autodesignNY for options.
Thanks for all of your help!

Today following Edgy01's (Thanks Dan!) DIY, I pulled the PCM out to send to NJ for repair After I pulled the top connector I saw it..A 10 amp fuse!!! pulled the fuse out, yup it's burnt. put new fuse in..immediate CD player sounds... Porsche screen comes alive...radio starts playing. WooHoo! So instead of hours of I-84 slogging I can drive someplace fun instead!
The whole job took about 1 1/2 hours. Unfortunately I couldn't see any way to change the fuse without pulling the unit out. But once you get started it really isn't too difficult a job.
Thanks Everyone, for your help/suggestions.

So how do you pull the unit and is the 10 amp fuse on the unit a standard automotive fuse?

Here you go.
Here is a great DIY for PCM removal https://rennlist.com/forums/997-foru...ion-guide.html,
The 10 amp fuse in the back of the pcm module is a standard plastic blade type fuse. It's located on the drivers side of the unit next to the antenna and other connections.

If it's the first time you are pulling out your PCM you will find the side leather panels will fight you a bit. Be patient. Best of luck!
Also, you are not the first to experience a reversed polarity battery installation. For some reason this happens more often than it should. I am seriously considering putting (on the mounting plate) a red sticker and a black sticker. I may even put one of each on the hood, itself, above the area of the battery. I put a new battery in recently and I took the carpenter's approach--measure twice and cut once. I looked several times before I hooked up the leads.

I wrapped the positive cable with red electrical tape. Can't hurt!

Same thing happened to me when I tried to remove the side panels. They need to be pulled straight out. I wiggled mine a little to much and snapped the top clip on the left hand side. Seems to still hold in place well but little things like that annoy me!
Well done on finding the fuse on the PCM.

Sorry slow to update. I am pleased to report that the PCM removal went smoothly (thanks to the excellent instructions here!) and once the fuse at the back was replaced the unit lit right up and has been functioning perfectly since. Thanks for the great info. Cheers,
