1990 Tach Question

[forbeer]

First of all. Hello all i am new to the XJ thing, however i am an avid shortwheelbase fan.

my father has a 1990 XJ and is trying to connect an aftermarket tach. there are several wires coming from the coil. anybody know which wire to use on the coil for tach hookup?


thanks,
Nick

nick.. welcome just do a guage swap... easy and cheaper than adding an aftermarket tach...
