This^^... I had a Redtop with all the Redtop stuff, Harness, ECU and all. That motor took a dump and warranty got me a Blacktop and everything worked fine.

if the late model blacktop harness is J4 then you need to re-wire at the ecu a few pins

The only difference is the O2 sensor- Everything else will work fine.
