[s-cars] RE: R134a, etc.

You can take out the low pressure switch, jump it...
Then if the Schrader valve connects are correct charge thru that.
Some compressors have a port on them as well, in the low side.

I didn't say anything , you didn't hear it from me.. If the EPA comes
knocking I have no idea :)
