will a truck wireharness and computer work in a fbody ?
 

would the wire harness and computer from a truck connect/bolt to a ls1 fbody and work with out any issues ?

You mean like the whole thing?

yes can i take the harness and computer from a truck with a 5.3/6.0 and put it in a ls1 fbody thats missing its harness and computer ?

is it direct swap or ?

I got a ls f body harness I can sell you.

so you mean just the engine harness?

And I'd be very surprised if it worked w/o modification.

unless you mean the actual whole harness, which then my answer of course not.

if 411 ECU, you have a change but you would need to check the pin outs. Everything thing is there, just need to make sure its in the proper location. If you have a later truck harness (E38 ecu, fly by wire), then no. Unless you are swapping everything.

If teh later, just coin up for the proper harness.
