Default LT4 MAF wiring

Had idler pulley seize on my 2019 LT4 which took out the the two drive belts which pulled the wiring out of the Mass air flow plug. What are my options? Looking at the plug it is not obvious how to reterminate the wires. I see extender harnesses which I could splice in but not ideal.

Not sure exactly what you're asking. Looks like they use a metripack connector, probably 150 series. The wire order I find is like the pic below.

Thx, but mine has 7 wires. Connector with a red locking tab. I know the coloured wire positions. Have figured out how to pull off the connector retainer but not how to get the individual wire pins out.Name:  20230813_080738.jpg

That is a Molex connector, not Metripack...
