I have been searching these posts for info on wiring my 89 Cherokee so I can pull my trailer, I have a harness that has a converter from 5 to 4 as I read ... now I dont know what wires to slice into what and I dont know if I am supposed to do this with wire nuts or some other wiring strategy, also I read on some threads that people are recommending these plug and play t connectors but I cant find any part numbers or references as to the exact part I should order to be compatible with my 89 xj , any help with either way of getting this job done is greatly appreciated !!
