Ls 5.3 truck motor and 4L60e into 50 burb info

I made the plunge into the Ls world today.it came out of a 2002 1/2 ton truck. I bought a 5.3 and a 4L60e transmission to put in my 1950 suburban.i made sure it came with everything including the computer and harness. It currently has a 383 stroker motor and a turbo 350 transmission.i was wondering what is the most affordable and easiest wire harness aftermarket or using the original to run the engine and transmission.i have a basic understanding of wiring.also want to know what engine and transmission mounts work good?also what exhaust manifold or headers work best?What are you guys running?Any advise is appreciated.

Re-use your wiring harness and use lt1tech.com for wiring info. The dirty dingo mounts are great and if factory manifolds don't work, the Trailblazer SS manifolds are the best universal fit I have found.

Cheapest is the stock harness you work over yourself, easiest is not that option. Its time consuming but not terribly difficult. Lots of guys like the PSI harness for easy plug and play.
ghettoluxury got it dead on.
