Electrical wiring on JWZ engine-ecu

[Saandy]

Hi guys:
Does any one know where I can find wiring diagrams for a 2002, M49 body, originally with a JWY engine?
I have a ventilators' issue that points to the BSI as the prime suspect and I need it for a few more issues.
Thanks in advance for the help.

I think they do a haynes manual for 2002?

Did you check fan speed resistor pack ?
Mont ago there was a post about it...
