FBH webasto I/O signals?

Im searching for a I/O list for the FBH unit.
Looking for a v+ signal when the FBH is active so i can hook up that signal to a LED.
That way i can see when the FBH is heating.

Take it from the small water pump next to the FBH ... As this is only powered when the FBH is running G4 Gone ...but not forgotten

purple and black wires as I remember.

i connected mine to a flashing red LED and ran the cables to the dash. now i can tell when the FBH is running rather than when it has received a startup signal.

the LED flashes faster as the pump runs quicker and is interesting to see when it starts and stops (in a nerdy kind of way

there are two wires that come out of the FBH in a seperate connector next the the multi wire connector. you can see these wires run down to the pump.

You won't be able to take a feed from the dash LED, as it is switched on an off by a CAN message, not hardwire.

The feed to the water pump is your best choice. 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

Unnecessary quote removed

It is a LED inside? either i will remove the LED becaurse i hate that stupid "greenlight" function that came with the clock-mod, otherwise it can be soldered into a cable from Webasto wather pump.
