Lighting in the gauges is out due to a fire or smoke getting out of the wire loom. Long story. However we got the fuel injection harness replaced but the lighting for the gauges is out. Without purchasing a new wire harness, I was wondering about the lighting pin off the big connection plug for the back of the gauges. Is there a schematic with what the pins are related to the speedo and other assignments?

BMW in question is a 1991 BMW K100LT
