Settings menu options were removed by Land Rover in a 2005 software update!
Does your car still have it in there?06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

It's not used (LR removed it on later models) so you can cut/splice/do what you wish with it.06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

FBH fuse is number 28 on the engine fuse box next to the battery.
The Red wire carries the W-bus data signal to the FBH.
You cant make the FBH start without a controller which can talk W-BUS.
If you put 12v on the Red wire you will probably damage the FBH electronics.
