Another FI 25 code

[Bartw]

Hello All
I've been reading this fourm since I picked up a 2002 GW (84K miles). Lots of great info on here.
I'm at a slight loss. As the title states FI 25 code, yes I know it's a right KS and the bike is running fine. I cleaned the connector, replaced the sensor, no change so I replaced the ECM (new from a dealer) but the bike is still throwing the 25 code.
My next step is to check for continuity from the sensor to the ECM and also check for a short.
If that fails what's my next step?
Thanks to all in advance.
Bart

Update, wiring, I have continuity and no short.
Update: I decided to swap the knock sensors and sure as S#i+ got error code 26. So the Knock sensor I bought was bad out of the package.

Was the new knock sensor an OEM on ???
