Title: 6.9 underbonnet wiring??????
Post by: Bandolero on 13 April 2006, 03:55 AM
Hope someone can help me here.
My 1978 6.9 has 3 separate 2-pin plugs under the bonnet that are near the fusebox and the battery.
1 is for the indicator light showing if the front brake pads are worn.
2 is for the brake master cylinder warning light, but I don't know what number 3 is for. It comes out of the fuse box and when I bridge the 2 wires together, the handbrake warning light comes on. However, the handbrake warning light comes on properly when I apply the handbrake, without this connector plugged into anything. (This connector goes nowhere and is not plugged into anything at all)
My 1979 280SE only has the 2 connectors, 1 for the pad wear and 2 is the master cylinder warning light.
I hate it when previous owners stuff up the electrics!!!!!!
