anyone know of a site that has wiring digrams. i have a 95 dodge 1 ton van that i am using as a tow rig and the oxygen sensor is telling the motor it is to lean, but i have replaced it and put it on a scanner and everything checks out fine except for the o2 sensor still says its lean. i talked with a mech. friend of mine and he says to check the wiring and make sure its not broke, i did that looks fine. pulled the computer out of it and tryed to see if i could find anything wrong with it. but looks fine. so i am stuck, i need to check the wires and do a continutity test. and if it passes that swap computers. thanks mike
