Attention: TDR Forum Junkies 
I appologize straight off for the long explaination. Started the pickup to head home and backing out of the parking spot I noticed the cummins didn't gather itself up like it usually does, rpms dropped and didn't come up until I hit the clutch. When I took off, same thing, touched the acc pedal and it was like I stabbed it. Hit the clutch again and found out I had two engine speeds, idle at 850 and if I just hinted at the pedal, it went straight to 1400 rpm's. Kind of like an on / off switch. No pedal = 850, any other pedal position = 1400. The check engine light came on as well as the water in fuel light. I pulled it over and drained the filter (couldn't really tell if there was water in the fuel or not) and the WIF light went off but it didn't change anything else. I fiddled with it some more and it finally acted normal and I made it the 200 miles home. It threw a 1693 (Fault in PCM / ECM), 0177 (water in fuel), 0522 (oil pressure sensor volts low) and a 1689 (no communication between ECM and Inj pump). I have an old Superchips in it and a friend said sometimes they go bad and it sounded like it might be my problem. Now for my question. I hooked back up the IATS where the superchips broke in between the harness and the sensor. I also unhooked the other pair of wires which were attached to a triangular plug with a yellow and a green wire down on the left front side of the engine. The cummins starts and runs up the rpm's like normal but I hesitate to drive it until I know if the triangle plug has to be hooked back up to something on the engine or is a diagnostic port maybe? Also in the same loom is an oval plug with a red/white and a black/white wire and it has a dummy plug in it. My Haynes manual says the IATS, WIFS and TPS are all on the same circuit but that is about all it tells me. 
Any help would be appreciated. Thank you, Jeff.
