Dumb question on adding tach cluster
so on a 1971 C10 that did not come with a factory tach how hard is it to hook up the tach to one of Classic Instruments new clusters with a tach?
Thanks,

Re: Dumb question on adding tach cluster
The factory tach's had a 2 wire harness which you can buy on line. The one in my picture was a stock one. 1 wire goes to the distributer marked on a HEI as tach and the other goes to the fuse block under the dash on any place that gets 12 volts with the truck running.
As the picture shows it's separate from the other harness.
