I removed instrument panel, dismount all instruments and measure out position for Transponder, 12V connector, PTT switch and intercom. A 57 mm hole for transponder was my big concern. Everything went well and instruments and switches are back again. Wires, AWG 22 and -16connected. New 12v connector 142-01-182, switch 110-34-089, *tt sw 110-34-831, No transponder yet.
