white if its tbi
what colour is the wire i use to hock up a tach on a 1989 Chevy 350
You can check for an instruction sheet at the manufacturer's website, but most tachs have a black wire for ground, a red wire that is hot, a white wire that is hot, and a green wire that goes to the negative or tach terminal of the coil.
green
look on the distributor cap, there is a slot marked "tach", connect the hot wire there and ground the other wire
Connect the green wire to the brown striped black wire.
light green
at the tach it is white-pink green at coil
one black,and one green
You need a wiring diagram for that answer. each vehicle is different.
one white wire goes to the distributor, the other goes nowhere. This is the lead that goes to the tach
The ground wire of the coil. Its the white wire with a black stripe.
You do need a switched live to the bat terminal, but not to the tach terminal. The tach terminal is the negative side of the coil, the bat terminal is the positive side of the coil. Normally the tach terminal is for the green wire from the tach.
