Question on 05 5.3L harness

[dropd80s]

I’m going through and getting my harness ready for the standalone conversion and have one question so far. I have found all necessary truck side connections that need to be made besides one. The 1999 pinout on LT1swap.com for the C2 connector shows 12V+ switched power (Pink) need at PIN C4 for circuit 239 for "Fused Ignition Positive Voltage - Mass Airflow Sensor". On the 2005 pinout (which is the year of harness I have) there is no PIN at C4 and no circuit labeled 239. The only "Mass Airflow Sensor" type circuit I see is an additional wire at circuit 439 added to PIN B10 on my 2005 harness (PIN C11 on the 1999) that shows to be "Ignition 1 Voltage - MAF/IAT Sensor" Anyone else mod their own 2005 harness and can confirm the MAF power was moved from circuit 239 PIN C4 in 1999 to combine with circuit 439 PIN B10 in 2005?

I will add a links I am referring to from LT1swap.com for both 1999 and 2005.
