Anyone know where I can find a engine harness for a 2003 chevy v8? Looking to swap the v6 out and put my 6.0 in it with the 58x to 24x conversion box

 

before I found a local one I almost bought one off ebay. there seemed to be a fair amount on there so I doubt it should be hard to find one. Check the classifieds here too, someone is bound to have one laying around.
