I am in need of a wiring diagram for a 1985 Houston Metro model 10 bus with a 748 Allison automatic transmission with a retarder. Can anyone help me figure out the wiring on this bus?
I need to know the wires that go from the retarder relay to the transmission brain box under the dash, etc. A diagram would be helpful as I need to know the wire numbers. I am in the process of trying to convert this old passenger bus into an entertainer bus for some friends who sing gospel music.
