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.
