I have a 90 with the speedo problem, bought a gauge set from a 91 and I discovered that the connector's don't match. There are 2 on the left side and one of them id different 90 has 4 connections, 91 has 6 connections. Pic forth coming. So looking for anybody that knows best what to do. Connector changed out, get a 91 even though it has connections, or will the 91 will not work? Maybe just try to fix the 90...
Thanks in advance
