yes...I installed the OEM myself and it's from Codealarm. go to their site and register and you'll be able to download the files. It's a large file..if ya want to give me your real email I'll forward it to you when I can but it ain't a small file.
I sent a PDF to Grim....If you want I can send it to you too. Lets see if he got it and if so you can PM either him or me your email and we'll send it along. You do have to register at codealarm to get stuff and you can find the model number with google search. Look for Mustang OEM alarms either VSS or RSS. I got mine on Ebay or Amazon for a bit over $120 but the install turned into a nightmare.
