Hi All,
Thanks everyone so much for the replies. I'll hold up on the SKREEM, and try to follow up on the electrical troubleshooting. I'm no electrical engineer, but I have used a DMM before on old Mustangs and as long it's just relays and wires I think I should be able to figure it out. I live in Escondido California, about 35 miles north east of San Diego. I re-flowed the solder in the RCM before as a preventative measure, but before I do that again, I'll first look to see if the appropriate relays are closed as suggested by T. One other thing is that along with the four wires under the battery that got chewed, there was a gray air? line under there that was chewed up - I fixed that one as well, but I don't know what it does - probably not related... I thought it was part of the pneumatic lines that control the locks, but all the locks worked before and still do. Having the transmission stuck in park is a PITA - the car was blocking the garage and I had to move it further back in the driveway - I ended up buying wheel dollys from Harbor Freight for $65, putting them under rear wheels. Since I was on a slight incline, my wife was behind the wheel to steer and use the brakes (front brakes worked) while I pushed. The small wheels (2.5 inch dia) on the dollys aren't the most convenient, but it worked.

Thanks again for all the advice, I'll probably only be able to work on the car on the weekends so my responses maybe limited to Saturday or Sunday nights
Sincerely
-Jerry
