when going from a h23a1 to a h22a4, which accessories (p.s., alt, a/c comp.) can i keep if any?

i am running a JDM RHD steering rack and would like to save power steering. i have a JDM power steering line but it is for the older pump since that's all that year of car would have come with. even if i have to use a different pump, will that line still work?

 

also, i am running an JDM OBD I H22 wiring harness on this motor. what mods will i need to make to the harness to go from h22a1 to h22a4? and if i do have to switch out the accessories to 97+ will the engine harness need any mod to fit the new alt. or a/c comp.?
