The C219 connector is the one going through the firewall. Unfortunately the circuits do not have the description, only the circuit code (ie L50) and the wire color and gauge (18 wt/tn).

So you will have to locate the circuit code for all the under hood stuff (start with the ECM connectors) and see what goes into the passenger compartment. Just taking a quick glance the D21, D20, and F202 go from the PCM to the C219. I think you will find that you will need very few wires going from the engine to the passenger compartment to make it run. Most likely are B+ (A209) and switched ign start/run (F202).

One last thing. Do you know the VIN of the truck the engine came out of? You are going to need it to see if the truck had a SKIM key. If it did, you also need the SKIM module and the dealer will have to program it with new keys so you can start it. Otherwise you need a new PCM and they are over $1000. 00
