[Kirk]

I've got a 2003 sonoma cc one a sas. With35s sbc powerth400 and a np205 case also a completely stock intrerio and I need complete wiring diagrams to buy because I want it all to work, so does anyone know of any for sale? Must be a factory manual Thanks Kirk

Helm Inc. sells the complete set. I paid $120 for mine IIRC
Looks like $200 and out of stock for 2004 now. , the 2001 is available, $200

I called helms and they want 300.00 for the set. So I'll order next week if I can't figure this out. I've got just about everything working but can't get the BCM to enter the program phase. This is a 350 swap truck so I have no serial data to the bcm all other inputs seem to be fine. If the ignition key is in the drivers door won't lock with the power locks. When the alarm sounds you can turn it off with the key in the drivers door. Interior lights ac horn radio door switches and all work. Security light is out with the doors closed but on and flashing with the key in the run position. All ideas would help, Thanks. Kirk

So you have a 350 swap but you are not running the PCM only the BCM? To get the truck to program its going to need the PCM, BCM and key tumbler all on the serial bus. I know the PCM can be programmed to run in standalone without any of that but I have no idea if the BCM can be done the same way.
