Thanks a Million (at rate of 1 thank you per word of instruction) for very detailed installation instructions. Nothing like getting info from someone, "who has been there and scratched his knuckles".

Your instructions apply except tuner and well are located on driver's side of trunk in 92 500SL (battery is in well on passenger side). I have all of the cables you described. The only thing I am missing is mounting bracket and, as you suggested, l will try to buy it from Walter Odemer, Inc.

Thanks again, Don
