made the gussets for the EFIS channels in the rearr cabin top wired in two more LED dome lights drilled holes in the front top corner wraps for wires to pass through on their way the wings since the EFII system doesnt have a mixture knob the only way to shut down the engine is to turn off the key, but doing this turns off everything so I wired in a guarded switch for the ECU the switch will shut down the engine and leave the lights and radios on Changed the wires on the Keyed master switch the old ones were not secure
