Vaccuum hoses for a 91 v6 4.3

I need to know does anyone have a layout of all the vaccuum hoses for a 1991 S-10 V6 4.3l truck.
I have replaced ym motor and it is acting weird like the timing is way off, we have it perty close but everybody says to check the vaccuums.:banghead:

Thanks all who can help.
