hello, I have 2002 Dodge Ram 1500 quad cab SB 4.7L 4x4. Been looking to do a 5.7 Hemi swap. I have tried looking for an answer to my question in other forums and this one but can’t seem to find it. If this is already covered can someone please link it to me? When swapping the 5.7 into my truck I know you have to get matching harnesses, but I have heard there are 5 different engine harnesses and 10 different headlight to dash harnesses. Also curious what’s the best year 5.7 to put into my 2002.

Thanks for your time,
Christian
