Wiring information on Rotax 503

[Blue Chips]

Friend of mine is putting a single carb 503 on his Challenger II which currently has a dual carb 503.
Problem is, the engine wiring connectors on the single carb is different then what is on the aircraft, also wiring colors differ.

Any one have an idea where one might get some wiring schematics?

503 Model 555581 currently installed
503 Model 4154410 to be installed

Thanks
Ken
