Gen 2 – P0037 wiring issue



Purchased an 03 H6 OB from a young kid that butchered the ecu harness on the car side trying to replace O2 sensor to correct P0037. Needless to say, here I am with all new sensors still getting same code. I’ve spent months trying to rewire correct tly going through multiple diagrams with no luck. P0037 just won’t go away. Can someone, anyone help with a proper schematic so I can finally wire it correctly ? I’m now start to get othe codes for knock sensor, AIT and neutral park switch. Most of which I’m sure has to do with the shoddy wiring job. Would like to fix before I have to ha e it towed to a scrap yard. TIA
