In with the wiring diagrams in the 74 manual are charts/ drawings of the various connectors with their locations I don't have a 74 manual handy, but in the 73 manual it looks to be the A/C low pressure switch

I bet you’re right. I believed it to be AC related as this car was and no longer is. I need wiring diagrams. Anyone know where I can find one ?
