Hello all,

To start Ive already searched this issue and come up with nothing. Im looking at putting a sunpro II tach into a 2001 F-150 lariat 4x4. BUT all the topics on this talk about 4 wires- red, black, green, and white.

This tach has- Red, Black, green with a yellow stripe, and green with a white stripe. Any ideas?

So far I would guess Green with yellow strip is Green and green with white stripe is white. But before I go and waste a bunch of wiring on this, any ideas?

Thanks.

 

alright. Well I figured out I was right on my guess about the wires.

but now I'm wondering were the negative output on the coil pack is.
