I have a 2006 1500 shortbed 2wd. It currently has a 4.8 and i want to build a 6.0 to put in it. Will the current wiring harness work on the 6.0? Also would i be able to order a computer or send mine in to be programmed or would i have to get a new computer? Sorry if these seem like simple questions i am just getting my feet wet with the LS stuff.

Thanks
Chuck
