Hi all you guys from America.
I have to repair an RPM meter for 1990 Pontiac Bonneville, but i have no diagrams for this car nor i can not find any on the net.
I found there is no pulse input to the cluster, or it is very weak.
Does any one old enough and can remember if the pulse of the RPM to the cluster is coming from the ECU or is it coming from the massive distributor located near the front right fender ?
Where is the ECU in this car ?
Any one with diagrams ?
Thanks for any idea.
