Black- Ground
Gray- To Tach Signal Input
Red- Coil Packs 12v+ wire (blue wire on engine harness)
Red/Green- Coil Packs 12v+ wire (same as above)
This is how the instructions seemed to reccommend but I am still getting no reading at all on my tach. I'm trying to find info from someone who has done this before since all the searches I've found come to a dead end.
I know there are people out there using auto meter tachs on sr's so please chime in if you can help! Thanks[/QUOTE]
On the coil pack 12+ wire, cut it and the other end connects to the red and the other connects to the red/green. I think this is what I did...just try it.Goodluck!
