Hi Chris-
Check you email, I finally got back to the dorms and off my lazy ass to reply to you... ANYHOW, what plug we talkin' here? The big black plastic rectangular plug that contacts the printed circuit? If so, its not the years that are different, the idiot light and tach dash used different harnesses. In the email I sent you I mentioned how I got around it, if you can't understand what I was saying drop me a line, too lazy to retype it all here. If you don't decide to go the same route I did you have to find the plug connector from a tach car and match up wire colors... My way was easier, cheaper, but uglier, lol. If you're talking about the tach lead itself, the 2 prong deal, disregard all that crap, I found a connector that fit in that laying around my garage. Good luck, if you need any more help ask quick while its all still fresh in my head /forums/images/icons/wink.gif.
