Thanks to all who responded to tire size and dash light questions. I just discovered that I need to change my wiring harness. There are five or six wires that are bare going into the connection block. looks like they have been repaired a time or two. I slit the cover which bundles the wires and then drops behind the engine and some of them are bare too. 25 years of heat from the manifold was just too much. I have not done this but it looks to be something I can tackle. The Bentley handbook does not have much addressing this, is there any site that would be helpful? I have a 85 turbo wagon
