I was trying to replace my speedometer in my 71 conv, with the one with a tach out of a 73 mach, I thought this was going to go smoothly until i got to the plug in the back, they are different sizes, the one out of the mach is smaller than the one in the 71.. Is there someone who makes a converter, or am I going to have to use a different harness or what?

Thanks!

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.

Hehe, there's a way.. It ain't pretty, but its effective... If you actually want to know what I did post again, too lazy and hungry to type it now, LOL.

Good luck, it worked out real well for me and I didn't have any problems at all... If you have any ?'s or get stuck, give me a yell, I'm sure my wiring diagrams are still laying around here somewheres.

Not a big deal though, to solder on the wires i had to sand the circuit a little bit to get the solder to stick, then I kinda encased them all the solder joints in epoxy to insulate them and to protect them.
