The new US-made step drill came in at Ace to I picked that up only to find the 5/16" hole I'd already made for bushings was appropriately sized. Guess you can never have too many step drill bits. Installed the bushings after determining the ring connectors would not fit through the bushing. So cut off the connector, ran th wire, and crimped on a new ring terminal. Then snugged it down. I also went back to an earlier instruction (42MiS/U-02 Figure 2) to countersink a couple of holes for a connector. Done. We'll see if it's countersunk enough later, I guess. And I did more separating of the wiring harness and examining of the plans . The instructions say: "Connect the Fuel Pump 1 (Main) and Fuel Pump 2 (Aux) connectors from the main harness to the corresponding connectors from the Rotax ECU harness. See Figure 1." That's confusing. There's no connector labels on either connector (just number IDs on the wire). And I don't see the connectors on the Rotax ECU harness. Figure 1 isn't particularly helpful.
