Low freon lvl A/C Clutch won't engage

I know how to jump the safety on my Jeep but can anyone tell me how to jump the low pressure switch on my 1986 SEL420 so I can add freon?

Try grounding it or You can jump the terminals on the KLIMA relay (can't tell you which ones)

I know on the older cars if you just set it on high and start adding freon it will engage and then suck in the rest.
