I'm about to buy a 91 civic,and it doesnt have a tach...i like to see the rpms,so what i was wondering was could i get a autometer tach...or should i just swap out the cluster for a different one...it will really bother me that i can not see what rpm im at....basically what im asking is how can i hook up a tach if i were to get a autometer one...i just dont know where i would have to hook everything up...any input would be great...thanks
