Just baught another HUD cuz mine was not working...i baught it, installed it checked if it worked and it did(thanks you Street_Sweeper). OK so i put everything back togerther and was all happy and was gonna take it for a drive....but now the RPMs dont work....everything esle does though. My rpms in my other cluster did(but the HUD didnt lol). Ok so here is my theory, my cluster redlines at 7K, this one redlines at 6K, so im thinking the cluster is from a SOHC, and mine is DOHC.....does that have to do with anything? Can i get my old cluster and switch the RPM guage with this one and will it work? Its not a BIG deal i can drive without an rpm gauge...but im just picky about things i want it working right.
