On my 1983 UrQ, does the oil pressure sender simply activate the low pressure warning lamp or does it have any connection to the FTCU? I'm at work and don't have the wiring diagrams. I can't remember if the sender triggers ground when activated? I know it is the opposite function of the 1.8 bar switch on the combined oil pressure gauge senders of later coupes. Thanks.
