I have a basic Blazer with only a speedometer and four other gauges. Would it be difficult to install a factory set of gauges with a tach? What besides the gauges would I need to change?

Also I had already searched and only found out that it should just plug in, but I wanted to make sure my truck already had the set-up to install one with a tach.

 

Yeah if you can find a cluster for your year blazer with a tach it should plug right in and work.

 

Has to be same motor and tranny, and the years can change but easier to just find one the same year.

 

Thanks for the help. But if I find one from a manual then it won't for on my auto?
