nope. not there. if you do a search, i posted a how-to on swapping for cobra/export mirrors. i have lots of pictures of the inside of my door and the only wiring harness in there is for the mirrors.
embrace your 248a, it will last a lot longer than the powered 'stangs.
P.S. my brother bought me aftermarket electric door locks for my birthday.... 4 wire install. if you want power locks badly enough, google them and get some aftermarket stuff.
Woody- I thought the same thing did some poking around and couldnt find anything.
MustangChris- I like the 248A thats why I bought but its killing me in resale and trade. I bought at tax time for $6,000 with 57,000 miles and I went to trade it on an new edge convert. and the dealer offered me $2,000 for it and said he would give me $5,000 if it had power options.
