    What does the acronym CMP and CKP stand for?

    CMP = Cam Position Sensor. CKP = Crank Position Sensor.

    Thanks - another question - I noticed that you did not mention adding in the LS MAF connector - are you implying that I use the old 5.7 MAF and IAT?

    Hhmmm, You're right. Thanks for pointing that out. That is an oversight on my part. You should use the 5 wire MAF. I will add that to the file.

    No problem - This wiring stuff can be a nightmare and I appreciate your help!

    Well - removed all the wires from the old 98 Vortec C1, C2, C3, and C4 connectors and got them pinned into the new Vortec C1 and C2 connectors - It wasn't that bad at all. I then removed the injector wiring, coil wiring, CKP, CMP, and MAF connector ends from an old 6.0L harness. Didn't get them connected into the old harness yet, maybe tomorrow night. Thanks Lextech!

    What are you guys doing for exhaust on your conversions? I noticed that there is ample room on the drivers side between the frame and transfer case to run a true duel system - has anyone done this on an OBS?

    Another question - How are you guys adapting into the OBS fuel lines?

    Ok - It's alive! But I have a few issues - none of my factory gauges work, I'm thinking I need the factory 5.7 sending units - maybe I missed that?!
