Rich, assuming your 190E has a serpentine belt (which I believe it does), the alternator should bolt on. You will probably need to use the pulley from your old 65A but otherwise it should work. You'll need to beef up the cable to the battery, I'd use 4ga minimum (or a pair of 4ga), better yet use 2ga or 0ga. So far I've been really happy with my setup, I plan to install a second 143A on my other car too!
Good luck,
