My tach and speedo are going out intermittently at the same time. Where should I look first? Everything seems ok under the dash but its difficult to make heads or tails with all of the old wiring under the cockpit.
I repowered from an OX66 to a SHO years back and I guess the dealer left all of the old stuff under there. Does anyone have a wiring diagram so that I can rip out what I don't need?
Thanks 😊
