So a few months back i did the sr5 gauge cluster swap into my 88 22re. The tach has never read correctly. max is 4-4500 rpm roughly. the tach is from an 89 was told it was a 4 cyl but im thinking it might be from a 6. is there any way to make the tach read right or am i stuck with either getting a 4 cyl tach or an aftermarket one?

Read thru there. Everything you need to know.

 

Thanks. i saw that thread quickly browsed it must have missed the part about changing the resistance! so im assuming that potentiometer will adjust my resistances

 

so that write up is for 2nd gen gauge cluster. i have my first gen one apart but its a lot different inside.... anyone know where to test resistance on the first gen cluster and how to remove the plates without breaking anything.

Edit: figured it out. thanks again for the help. gonna go plug it in and see if she works!
