Would it be possible for me to buy the engine and ecm separately? Or would I be able to buy an aftermarket wiring harness specific to my 71 Blazer? I am new to all of this information and really appreciate all of your inputs

U can buy it all seperate, just have to know what all you got so the person/company doing the work knows the whole set up.
And I am not aware of a specific 71 Blazer harness, most of them are generic but work in many vehicles. As easy as it is, why pay the Painless (LOL) prices? get a good harness and do it yourself or send it off or just leave it as is.....you do remove some wiring you dont need but its alot of work.

So it would be easier to buy a wiring harness that is specific to the 5.3 engine?
