Thanks Bob.... I knew if I asked, you guys would have the answer. Not much is going on, getting the last few parts, temp sending unit for the p/s for my gaugeand few misc parts. Still not sure about the original oil pressure sending unit, was told that if you do not use it it would give a low pressure code in the ECM and shut down the engine. Do you know anything about that? Think I am going to tap the oil cooler line fitting and use that.
