Oh yeah, I forgot you were in Canada. They may have started using that trim name up there first. I know many cars that were the same had different names up there. Here, the S500 didnt come out until late '93 as a '94 model. We had "SE" or "SEL" after the numbers on the 92-93 S-Class sedans here... the SE was ther shorter wheelbase model and the SEL was the long wheelbase mode, but they were the same car, no changes that I am aware of until the '96 or was it '97? freshening.

Hopefully someone really smart on these cars and tell you about the wiring harness year. I know my uncles was made in late '91 and has had no problems, but the '93 400SEL I am about to purchase was made in 11/92 I believe and obviously had the bad wiring harness, as it was replaced in 2001.

Good luck!
