Have multiple electrical problems with '99 Disco 2. Headlite warning chime is inop, no o-head lite when left frt door is open, abs,tc, and hill descent lites are on, have power to yellow trailer wire back to left rear trailer lite, but no left directional or left rear brake lite. Right side of trailer works fine. Have checked fuses and all are good, have called technician to make appt to clear abs codes with Autologics scanner.... Does anyone have any good advice or remedies for these bugs? Thanx, Mikey
