Tachometer instrument cluster installation

There are two ignition coils one is for one and two cylinder, the other is for three and four cylinder. Which one do I attach the wire to?

Thank you. I will defiantly try this.

I could be mistaken but I wanted a tachometer on my 2000 2.2 automatic rear wheel driver S-10. I took the instrument cluster out of an s-10 extreme (1999) and now I have a tachometer so the same should work for you. Cost me $15.00 at the junk yard it was plug and play basically once I pulled the dash apart a little. Hope this helps. :)

Jacob62. I did pull a different cluster from a similar year vehicle but I did not have the wire to hook up to the harness in the back of the cluster. I hooked up the wire according to the wiring diagram that ASEMaster6371 so graciously sent me. It did work with a little patience and aggravation but I got it! Thank you both so much for your inputs! I hope this helps anyone else out there that needs similar assistance!

Hello,
Just wanted to get back to this post.
Review 1997 Chevrolet S1O 2, 2 five speed.
I had asked about installing an instrument cluster with a tachometer. I read all previous posts. Well I finally got back to this project. I purchased a cluster with a tachometer that came out of a 1997 V6, it had about the same mileage so I was happy about that. I pulled the cluster connector loose from the the dash to make it easier to test and viola the tachometer And all othe gauges worked perfectly. Needless to say I am extremely happy. So I do not know what to say about needing to run a wire?
It was plug and play for me.
Maybe because I used same year clusters 1997?
Maybe because there may have been a cluster with tack originally?
Or I just got lucky, I doubt that.

But the cluster did have white wire and truck harness did have white wire, maybe they went to a standard harness in 1997, who knows, I do not.
Good luck.
