Hello Luke,
You can download the installation manual here (even in your own language  ). Hope this helps. Cheers, Vincent

From relay K3 you should have one RED wire and one BLACK wire which you need to connect?
If that is correct then I have just worked this out for you: For a Puma you need to cut the ORANGE wire which goes to the motor fan (blower). The RED from K3 should be connected to the part which comes from the fan fuse. The BLACK from K3 should be connected to the part which goes to the fan. You can, however, do this at the fuse box as I think the Puma fan and connector is hidden? The Fuse is number 45 (30 Amps) under the steering wheel. Remove the fuse. This "cuts" the circuit to the fan. You can then use the RED and BLACK from the K3 relay. Add a new fuse holder to the RED wire from relay K3, and push in the 30 Amp fuse you removed above. Then crimp 4.8mm wide (not 6.3mm) spade terminals to the RED and BLACK wires from relay K3, and fit one into each side of fuse position 45. Make sure the terminals are insulated from each other and do not touch! 
You should fit the RED wire with your new fuse holder to the side of the fuse 45 position which connects to the ignition switch, and the BLACK wire to the side which goes to the fan. You can find this out which is which like this: With the fuse removed, turn the ignition switch to "I" (radio comes on). Use a multimeter to find the side of the fuse box slot which has 12V. This is the ignition switch side. Turn the ignition switch off, and fit the RED wire here. Fit the BLACK wire on the other side. You now have a fan which is under control of the TT-C and the K3 relay, as well as working normally. And no cutting of the car loom required  1988 90 Td5 NAS soft top

If you have feedback on what I worked out for you above please let me know - did it work or not?

Martin/luke - the following is from a pdf (Part 5 - Completing the Installation) in My Gallery. I cut the orange wire on the fan loom as per the section below - which I think is the same as your instructions Martin:
Connect the wiring loom to the vehicle fan. a. Locate the grey connector with a brown/red wire and an orange wire that is connected to the fan motor (passenger side bulkhead) – cut the orange wire. b. To remove the grey connector locate the square hole in the heater housing underneath the connector (i.e. where the grey connector goes in), Push the grey connector fully home, insert flat bladed screwdriver into slot and jiggle around, curse and swear for two minutes until grey connector magically pops out and you wonder what all the fuss was about! c. Connect the black wire from the Webasto loom to the orange wire at the grey plug end i.e. black going into the fan. (I’ll explain why in a minute) d. Connect the red wire from the Webasto loom to the other orange wire, i.e. going back into the vehicle’s wiring loom. e. Use proper connectors and heat shrink tubing or similar to seal. f. Replace the grey connector g. How does it work? The red and black wires are connected together at the relay (the one you fixed to the bulkhead with the rivnut) When the Webasto is turned off, i.e. under normal vehicle operation, these red and black wires simply form a loop which connects the two cut ends of the orange wire so the fan can operate normally. When the Webasto is switched on however the Webasto needs to provide power to the fan and switch it on. It does this by providing power to the relay which disconnects the red wire and provides 12V to the black wire. This is why you need to connect the black wire to the grey connector end to make it work and not the red (which would be more logical to my mind – but then I’m not an electrician). I’ve read somewhere that the fan gets switched on when the coolant temperature is above 30C however mine seems to come on as soon as the Webasto is switched on. |
