Good evening new to the forum need some info on a 5.2 to 5.9 swap original is a 99 ram 4x4 with over 400,000 miles on original motor but believe crank broke or through a rod bearing, bought a 2000 ram 4x4 with 5.9 to throw in it until I get the original rebuilt, my question is in regards to the wiring harness it appears the original harness is different from the 5.9 I already swapped flex plate, but will original harness hook up to donor motor
