Hello all,

First snag I've run into in my reading. On an ls7 engine, what are the acceptable donor engine harnesses if I want to stay dbw and on an ls7ecm? My preference would be an easy to obtain truck harness, but it seems ls3/l99 are the closest? What about the vortex 6000/6200, they should be near identical minus the auto trans, correct? As long as its not a 24tooth crank, am I good, so 05+ ls2 dbw harness or better?

A lot of info to wade through, so far in getting along alright though.


Thanks
