adding a tach

[lostissues]

I'm thinking about adding a tach instead of a gauge swap, i don't have the idiot lights, but i don't have a tach. so all i realy need is a tach, is it posible to add an aftermarket tach to my truck? where do i get the signal from? anyone have any suggestion for a tach?

 

Thanks

I'm using a Sun SuperTach II in my '88. Tap the signal off the coil pack. I believe the instructions for my tach said to take it off the wire from the coil to ground, but I don't remember now. It's been in there for four or five years.

it's the green and white (or yellow?) wire coming from the coil. that wire runs all the way to the back of your gauge cluster...so you can tap the wire back there and avoid having to run new wires.
