swapping in an aw4.........

i'm swapping in an aw4 into a wrangler and i was wondering if the tcu is controlled by the main computer or is it ok to wire by itself? if it is does anyone know of a place i can get a wiring diagram for it. ---thanks

this is for 87-90 TCUs, 91+ might be different.

Man, I wish I could remember the link, but someone posted an AWESOME aw-4 into a tj write-up.....
