Which wire in the instrument cluster is the tach wire on a 91 240?  Also, where is the best place to wire in light and power on aftermarket guages? thanks.

I think the best place to run the lights for guages is through your parking lights in the steering column. That way when you turn on your lights your guage lights will also come on. As for the tach wire on a 240 I am not sure.

Does anyone know where the tach. wire on a 240 is?  also, what wire is the parking light (color)?  thanks

OK, I've got a 1990 and 1995 FSM, and for both years the tachometer wire is yellow/red - at least at the ECU and main dash harness.  Since both years are the same, I would assume that its consistent, BUT, that's just an assumption.  Sorry, I don't have a 1991 FSM...

Well This is what I did take off the column cover get a volt test light there will be two harness to the light switch put the key in the ing turn it to acc then test out the two harness for the one that will only come on when you turn the switch on I did it today but I forgot what color it was I think it was brown and blue. The harness connector was brown though.
