Iv'e read all this but i still have a few questions.have an 05 with the 4.3 took it out put in a 01 5.3 even used the stock v6 mounts .were have problems with the harness for trans we had to swap that plug to the old v6 harness does any one have a read out for that plug its what holding us back from the swap being completed.or do we have to use a differen't harness trying no to have to use the dbw we have the dbc on it now?

you need to get a 2004-up harness. the pinouts are different. if ur truck were to come with a V8, it would have been dbw.

so is it possible to move the pins to make the 99-02 dbc harness to fit a 03 4.3 dbc fuse block?
