Do you already have the motor, what are you doing for a tranny, and are you staying fuel injected?
I think Painless Wiring has a few harnesses, but you might want to look into picking up a wrecked F-body to use as a donor

ill be picking up the motor on sunday, for tranny im not sure yet, was thinking of using the original tranny for that engine, not sure how it would work on my car. i would like to keep the engine fuel injected. also, what is an F-Body? also, if i do get this engine and tranny will i have to change the rear end gear ratio? thanks for your help.

im getting the motor on sunday, it will be coming out of a trans am or a firebird??hmm. but it is complete, has the computer and all wiring harnesses. i do want to keep it fuel injected, also will i have to change out the gear ration in the rearend, my intentions are to use the tranny that came with that engine, it is a 2002 engine. what other tranny will work with this, a 350 turbo or a 400?? thank you for your help.

here's the pan you will need, motor and trans mounts. and nice headers.
you can use the stock harness to the computer but from computer to the car harness ignition ect painless makes one for that. if you do go carbed, painless makes one for that also. which is color coded and from what i hear very easy to do.

If you use the full F-body harness with the bcm (body control module) you could use the stock F-body gauges and fuel system (if you wanted to) then just make up the new fuel line from your tank to the motor... I'd strip everything off that F-body I could lol

Went you get it all together you can have the computer tuned to match your rearend ratio and tire size.

I'd love to see pics!
