I bought a complete takeout from a one of a kind escalade. This came with the

manifolds, all accesories, computer, harness, even the fusebox. Most of the

wiring is still hooked up, those that aren't are marked. I'm wondering, since

the harness is complete and put together w/the ecm, do I need an

aftermarket(SPeartech) harness? Or a better question is, what steps do I need

to take in order to start this badboy up????

Thanks in advance!!!
