bulkhead connector diagram?

hi im doing a motor swap into my 91 1500 4.3 V6 and im dropping in an 87 TPI 350 out of a camaro, i need the bulkhead wiring diagram for the truck so i can wire the TPI engine harness to the trucks interior harness, any ideas where i can find this diagram? i think the 4.3 diagram is the same as the 5 and the 5.7L.. my GM dealer couldnt find it and ive looked everywhere.
thanks

I think your GM dealer couldn't find it 'cause he didn't look hard enough. Otherwise you may have to spring for a service/wiring diagram manual from Helm, Inc.
