Hello paul.serpa@hotmail.com and welcome to the forum!
Check out this thread:
https://hiace-super-custom.forumotion.com/t4468-part-numbersand my post from Oct last year in particular.
While short and simple the bold text is well worth looking up online.
The last one mentioned there has the best engine and electrical manuals that are readily available online. It also has some very useful resources that every Hiace owner should have at their fingertips.
The forum also has loads of other link so look around though searching it isn’t that easy.
A few folk on here have various other manuals that have been shared around. It’s not possible to upload them on the forum but they can be shared by other means.
Hopefully the linked post has all you need to get you started.
Cheers!!
