re engine and trans ecu pin outs
I too would like these for my own maintenance. I am yet to find accurate data specific to the electronic pump , it is like rocking horse manure to obtain.
This is all I have on the electronic pump from a bighorn unknown year, although someone on here will probably know what model and year Isuzu had the electronic pump

I have a [147 pages] trans overview training manual that includes AW30-43LE as fitted to a volvo. again this is only a guide and not for specific wire locations in the trans and engine ecu connector plugs.
I do have this concept picture form a training manual on the re engine and trans ecu pinouts
this from a trans overview training manual AW30-43LE Model as fitted to a Volvo

Re the hook up the trans directly bypassing the engine ecu ,
Probably the easiest way is measuring of a known good vehicle prior to attempting as the signal may be 'conditioned' [inverted, power level change] to make it acceptable to the trans ecu. People [not me] can make signal modifying electronic black boxes if needed.
Would you consider fitting a known good correct electronic pump? If all else is in place how easy would that be ? I would consider it a more predictable outcome.
Measuring, designing, Fabricating and installing electronic signal modifiers to 'trick' the ecu is in the region of less than 0.1% common knowledge
saying that the above concept drawing only shows 2 inputs to the trans that are speed related
anyone know where the engine and trans ecu are mounted in a 97 wizard?
