Locating Check Engine Light Wiring

[Diesel_Weasel]

I recently bought the truck in my sig. I'd like to wire it up so I can see when the check engine light would light up.

The motor is a 2005 325 hp HPCR. Any clue on which wires to tap into to get the signal for the CEL?

I'd also like to know which wire powers the fuel pump relay?

Thanks

Jason
