Here ya's go
I will be hopefully getting a few more manuals soon, when I do I will update this post.
Hiace 1989 - 2004 Manual (Not just the engine, this is for the whole vehicle and includes SWB, LWB and SLWB Commuters) is here.
The manual for the 2LT / 3L Diesel Engine only is here.
And the manual for the 1KZ-TE Engine is here.
I hope that these will help someone out,
Cheers all,
