Hello. I have a 1982 244 GL and want to put auxilliary guages in the two holes ot the right of the main dash cluster. I went to the junkyard and bought a small clock and a tach from a 1988 240 GL and I also got a voltmeter from an '84. I need to know first whether the tach from the '88 will fit and if not, it doesn't matter because it only cost me $3.99 anyway and I can get another one from an earlier car. The mini clock wiring is easy, but I have no idea about the voltmeter. It has three wires coming from it and was hooked up kind of weird, spliced into wires that went to the cigarette lighter. Any help as to where these guage wires connect would be appreciated (I already know where the ground goes). Thanks
