Did some wiring in the wings. The heated Pitot and OAT probe need wires run that are not part of the stock wire harness. Installed the landing light into left wing. I have PAR 36 LED light from Amazon that I will try out. The lens trimming and installation needed special care not to scrath or crack the plastic. For the light mounting, order the OP-52A kit to get the hardware and mounting frames for the lights but delete the lights themselves. You only need the brackets and hardware.
