New gauge cluster with tach

I am going to be installing a new gauge cluster with 5K tach. My blazer does not currently have a tack, but it is the Taiwan reproduction of the OEM stock gauge cluster that I will be installing. Does anybody have a good advice before I start?

Lightbulb Re: New gauge cluster with tach

You should purchase the stand-alone tach harness. The separate tach harness is a very simple 2 wire. One wire connects to the negative terminal of the ignition coil. The other plugs into the fuse block in an IGN UNFUSED terminal.

Just saw that there is one for HEI. So I’m buying that harness since my Jimmy has been upgraded.

Re: New gauge cluster with tach

glad to see you painted your other gauge needles! nice work. So many people leave that step out and it becomes soooooo obvious that the tach is new.
