2000 Challenger 1800 tachometer use in a 1999 Challenger 1800

[Sean1]

Has anyone tried using a 2000 Challenger 1800 tachometer in a 1999 Challenger 1800 boat? Both of my tachs are not working and I wanted to hook up a working 2000 tach to begin diagnosing if it is wiring or tachometer issue.

If the engines are the same in would try it.

Thanks for the reply. I think I'll give it a try and I'll let you know how it goes
