Fitting size [edit: Now I know!]

[Turbinepowered]

Just a quick question, what size fitting fits on the QTD turbo drain port in the oil pan?

I'm fitting a K03 to my 1.5 in the Fox, but until it gets rebuilt I need to plug the port on the oil pan so I don't leak or contaminate my oil.

I took it to a bolt house, they whipped out the metric thread pitch gauges and a caliper.

The fitting is M22x1.5
