Van's solved the fuel pump wire mystery. They're still with the engine as there was no step in the instructions to route them into the cabin. The great Tony Kirk answers the mystery.

"Hi Bob,



I agree, we do not do a very good job detailing where the Fuel Pump connectors are located on the main ECU harness. We should add this info the next revision of section 42M.



In Figure 1 on page 46iS-07, the two connectors marked #19 are the fuel pump connectors. They originate from the main ECU harness at the Fuse Box Lane "B" X2 and the Lane "A" X1 connectors, shown in Figure 3, also on 46iS-07, see pic below.



The wires should be routed through the firewall “Modified AN931-6-16” grommet as shown on page 42MiS/U-14 marked-up in red (below). Unfortunately, the fuel pump connectors may need to be passed through the firewall grommet before you pass many of the other wires through the grommet because of their size.



After passing the FP connectors through the firewall they go down behind the Power Module through the large opening in the F-01202B-1, then to the mating connectors in the RV-12iS harness, as per the instructions you quote.



Fuel Pump identification can be found in the Rotax Heavy Maintenance Manual available at https://www.flyrotax.com/p/service/technical-documentation



If you need part numbers for the connectors themselves, that information is detailed on the Wiring Harness Schematic page 11.



Hopefully, this info gets you one step closer to completion."

When attaching the wires, I indicated on the plans which connection goes to which fuel pump.

Also attached the ground wire from the AV6000 power module.
