I noticed that and figured no good could come of it. Thank you for pointing it out and letting me know what would happen.

I was planning to upgrade the alternator to an 80A model by using the wiring harness from a 91 or 92 300E (I think that is right)......Is there an easy swap like this for one of the 90A alternators?
When ordering my voltage regulator from discount auto (just wanted to get something fast to see if it really was the VA) anyway, I saw an 80A Alternator that they are selling and was wondering if anyone had experiences with the chain store aftermarket parts?

Also, with the aftermarket 80A from Discount Auto it looked like it had two studs on the back so I am assuming someone who upgraded through that route would have to cut the connector off of the MB harness and crimp some new connectors on.....Is there anything wrong with doing it this way, I was thinking off getting something that can handle a new head unit and a couple amplifiers....maybe three if I try to fit a sub in somewhere.
So could I take any high quality high amperage alternator and use it.

I just do not want to keep buying alternators every time I decide to change something and would like to know what my options are.
