Sheesh they sound worse than monkeys ..monkey do better than that. Hey check the ground for the 4x4 system..follow harness to ground ..think it is on driver side frame. Will have grounds on intake at thermostat area and maybe behind the ac pump. Just run a ground from engine to chassi and frame that you can see. More grounds the merrier..you should see a state police car ..grounds everywhere i mean all over but the need for radios lights ect. If you read link i left maybe ground location for 4x4 system in it.
