Hi, I have a 1992 S-10 with a 2.8 motor I just recieved a Tach for x-mas, my coil has 2 plugs in it, one with a red & white wire & one with a red & black wire,can anyone tell me which wire I hook the tach to?.......................I know the old ones with a conventional coil hooks to the neg. side of coil.
Thanks for any help

I had an 89 s-10 4.3V6 and I bought a tach by "sun" from autozone and the instructions had what I needed to install it. Now I dont remember exactly where but it was at the dist.
kind of lame reply but it worked for me.
