Just completing a new Garmin upgrade to a friends -8. I am using a Stein Air harness wired to the GMC507 A/P with GSA28 pitch and roll servos and Ray Allen pitch and roll trim servos. My problem is that the pitch and roll modes are reversed, meaning that any pitch command on the A/P causes a roll input, and any roll command is causing a pitch input. I have quadruple checked the wiring and it appears to be correct. Pulling my hair out with this one!
