I saw your original reply that I would have to add the wiring to the dash. I think because I rebuilt my own OEM harness, following LT1SWAP.com instructions, and used his wire maps on his website, I made sure I pinned that out and added the wire(if it wasn't already there). And maybe the 2003 6.0L PCM has the Oil sender provisions. However, this was a year ago so I may be a little hazy on the exact reference here, but doing my research, all these computers were usually the same blueprint with different tunes so I think with a change to PCM tune you can turn the oil sender feature on/off in all these models. Then if the harness didn't have the wire, you just add it.
