...wrapped LED RED/WHT & WHT#22 Trim Pwr in red shrink wrap and crimped single fast on, 1 amp. fuse on Main Bus. Soldered ORG/GRN/BLU wires from MAC servo toLED indicator.Placed eyelets on 2 WHT wires soldered on diodes on Panel Elev. Trim switch & attached GRN & ORG wires from Trim Relay deck. LED light was centered & bright and the trim operated from the panel switch, but opposite to intent. Added eyes for attachment on #22 BRN/BLU wires for trim button up/down. Began panel slot for EFIS jump drive extender ordered from GRT so that I can update EFIS with a jump drive rather than inserting behind panel.
