I am in the UK & Briggs information is very limited Would any one have a 23hp efi engine ecu wiring diagram? I have searched the internet for 3 days and cannot find one anywhere, there are many diagrams for the big block Briggs but not the small. I have looked at fire pumps and Argo but none are listed on there. I bought it from a Water Utility Company sale, it is missing the front panel so no on and off switch and a couple of spare plugs which i guess maybe hour or tachometer, there is a long 6 pin plug which could be an ODB plug as the colours seem to match other models with a pink red & black but the yellow and green CanBus wires have been isolated. The ECU, electric fuel pump & loom have B&S part numbers but none of them are listed on any EPC. Did B&S use any other ECU manufacturers other than Delphi? It was made May 2018 so still a current model. Thanks in advance Update April 5th 2021 i have got it started and running cannot rev it up though ,. but need to know if i require a electronic Throttle position sensor or a cable to rev it up , it has a stepper motor on the throttle linkage, either that controls the governor or engine speed. Amazon delivery coming this afternoon hopefully this evening i can make up some sort of diagnostic plug and pull the information off the ecu with the laptop. Will keep you updated.

David hi david did you have any luck with the connecting to the ecu with that conector you ordered? i have just bought the same engine to build a pressure washer (i'm also in the UK btw) and i've only used small engines with carbs before. although the engine is new it is 3 years old and out of warranty and its going to be impossible fixing this thing without plugging into the ecu in a lot of cases. i've found some free software for the delphi mt05 ecu which i believe it uses, but need to be able to connect to the plug to an obd2 and into a laptop. it looks like the socket on the ecu isn't the standard 6 pin like on a lot of the mt05 ecu. so i wondered if you had any success? roland Quote #2

hi david

did you have any luck with the connecting to the ecu with that conector you ordered? i have just bought the same engine to build a pressure washer (i'm also in the UK btw) and i've only used small engines with carbs before. although the engine is new it is 3 years old and out of warranty and its going to be impossible fixing this thing without plugging into the ecu in a lot of cases. i've found some free software for the delphi mt05 ecu which i believe it uses, but need to be able to connect to the plug to an obd2 and into a laptop. it looks like the socket on the ecu isn't the standard 6 pin like on a lot of the mt05 ecu. so i wondered if you had any success?
