Fabricated DB25 connector for TXPNDR. Cabling: twisted pair for power and ground; twisted pair for serial TX/RX, single wire for IDENT. Also included a pigtail with 1.21k resistor for 2020 ADS-B out compliant GPS source when the time comes. (Since then, Dynon came out with their GPS-2020, which will communicate with the TXPNDR through the serial lines, so the extra line won't be needed).
Used Cleaveland close-quarters dimple dies to dimple holes in top of fuselage where the GPS antenna goes.
Ran TXPNDR cables from back to front. TXPNDR on the right side of the "tunnel", up the center u-channel enclosing the flap motor, under the cross-member, then under the passenger-side canopy deck.
