1988 Mariah Supra

[alex123]

I have a 1988 Mariah Supra that is going to need some work. I am having some electrical issues with it and was wondering if anyone had, or knew where I can find, a copy of the owners manual and/or a wiring diagram for the boat. Also any other information would be greatly appreciated.
Thanks!
