I'm reaching out to anybody I have 4 02 sensors one down stream the wires are cut off plug and all I have new plug and 02 but I can't find ware wires in harness but the other working downstream has someone was in there as there cut so do both downstream 02 share same 4 wires that go to ecm can I just splice into other 02? I would say it had single Exsaust and was changed to dual but it would have 2 and 3 are hooked in any info would be great I can't find a diagram or eavn a doner truck to look at thanks.
