I've got a P pump 24 valve but I can't be of too much help, it came to me this way already and it's a 96 truck and uses the 12 Valve harness and an assortment of 12 Valve sending units and such here and there on it, they combined the two engines and no check lights because the truck thinks it still has the original engine since the harness, truck and injection pump all match. From what little I know about the swap on a factory VP truck, you'll still have the check engine light if I'm correct. The easy fix- remove the check engine light bulb from the gauge cluster. With a P pump there's little reason to keep the bulb since most everything is mechanical on the engine then, there will be no way the engine can tell the truck it has a real problem anyhow. Cruise over to CompetitionDiesel.com or CumminsForum.com for more help, both have plenty of info on this swap and can tell you about everything you need to know about it and how to do it. CF has a specific p pump 24 valve swap forum even....
