Just bought 1986 flhtc peral white and autum gold. Just love this bike. But the oil temp guage does´t work thats in the faring.Looked at sending unit in oil tank and(NO WIRE ATTACHED) been one there the eyelet still there. I cant find where the wire is hanging under seat,broke off,or been cut. Can anybody tell me where the wire from the sending unit goes to make the temp guage work?
