Webasto timer wiring

[trikey]

Can anyone tell me where these three wires go to, I know the fourth black wire is an earth, but can't find where the others go to?

I do not have the female side of the plug on the car so need to connect them individually

Is this it ??

The plug that goes into the telestart T80 / T90 has 4 wires (yellow, grey, purple, black) the plug from the timer (at opposite end from where it plugs into the back of the timer obv) only has three as the black wire is separate (earth)
The timer plug goes into a the black connector seen in the top left of this picture, the plug that comes from the telestart also plugs in here, this plug/loom spurs off to the relay / theres a blue wire which goes to the FBH itself, it fits into pin 3 on the newer FBH. then a grey wire which would go into fuse 37 on MK2 fuse box along with a red/orange wire that goes from fuse 37 into the main fuse box in the engine bay.

The grey wire is connected to a permanent live via fuse 37 in the hardwired fusebox, supplying both the Telestart and the timer,

The black is connected to chassis earth, and both the Telestart and timer and is connected to one side of the pull in coil, and one switched side of the FBH relay, a normally open relay contact, the other side being connected to pin three of the FBH.

The yellow is looped through to the cubby box timer, and is a signal wire from the Telestart unit to the timer.

Finally the purple wire is the output from the timer and Telestart, this goes high when the timer is active, the flame button override pressed, or the Telestart operated, and is connected to the other side of the pull in coil of the FBH relay.


I'll include a couple of keywords for anyone searching in the future, for Telestart T80 wiring Webasto parking heater timer wiring, FBH wiring.

The other half of the plug must be hanging just inside the wheel arch liner then

Arctic in photo number 3 the round plug whats it for?

Hi Simon.
It is the antenna for the FBH from which the fob works to turn on the heater, the receiver end of it fits into the bottom of the bumper.
