Thanks for the replies,

After doing some more reading I think i may be in trouble on the wiring and
since I have no experience with a conversion I have a few questions.

Could someone give me a basic run down as to how many separate wiring harness my 03 4.3l has? I am thinking the motor wiring is one harness, then a separate harness for the transmission? So basically, how is the wiring laid out?

Will I need the fuse box from the donor vehicle? Which of course I do not have.

I am hoping that my chassis harness will be a direct fit with the new ECM? So the fuel system, gagues, speedometer ect..... will interface with the new ECM

Do you think custom wiring harness will have to be made for this to work?
