Default 2009 Sportster 1200 Low (ECM)

Hi guys!
Chase here. I'm new to the forums!
I bought this bike for a steal(not literally) for $950. The guy got tired of trying to fix it.
I believe that the ECM is bad, or the wrong one altogether. The Speedometer and Lamp Assembly is gone as well, as he had started parting it out before I found it. The ECM it has in it is part #32140-08 which, from what I've seen, is for an XR. Would this even work? I don't believe so, but maybe that's the issue. The part number should be 32534-05C or 32534-11(replaced 05c).
The engine does turn over manually, but no power to the start switch. Lights, horn, etc work.

Wiring diagram here - 99949-09_en - 2009 Wiring Diagrams (harley-davidson.com)

Start by getting power to all of the switches. Check fuse box is clean of corrosion and the relays and fuses are good. Get a speedo or something connected to see what codes are stored. Even perhaps if not the correct ECM so long as it is similar it should provide the 5 volts to the sensors which would be a test of some functionality.

I can't help with the differences in the ECM; of course a dealer would love to sell you a new one. Check ebay, they do come up from time to time.
