I've retro fitted a D8 trip computer in to my 306 HDI.
It all works a part from estimated fuel range.
I'm unsure if the D8 sends a voltage to the trip computer or I it drops to ground when the feul warning light comes on.
Can someone that has worked on a trip computer please tell me if wire 4310 is 12v when the fuel warn light comes on or is the wire 0V.
Talk about the 406's electrical system, what wires do what, how to add extra functionality, etc.
