I have a set of Porsche 986 tombstones that I want to install into my 2005 Audi TT. I believe them to have the power back/tilt and think they are the heated ones as they have the white connector underneath that has several wires going to it,this in turn goes to two black two pole connectors that I think are linked. I was hoping someone could tell me what colour wires do what. I'm not too great with wiring diagrams so if possible I would like pictures or just a description of wire colour and what it does. I have just one connector under the seat which connects to the car loom which has the little black 4 pin plug with wires in it coloured red/yellow, black/yellow, brown and yellow/white. The other wires go to the five male pins(6 pin plug,5 present ,4 used) and are coloured as follows the two doubled up in the same pin are brown, below them is a red/purple and lastly there are two heavier gauge wires that are brown and below it red. Any help would be greatly appreciated.

To help you with wiring the Porsche 986 tombstone seats into your 2005 Audi TT, let’s break down the wire colors you provided and their likely functions.

Audi TT Car Loom (Connector with 4 Pins):
• Red/Yellow: This could be a power wire, likely for the seat’s motor or heating system.
• Black/Yellow: This might be a ground or a signal wire for seat functions like tilt or adjustment.
• Brown: Typically, brown wires are used for ground connections.
• Yellow/White: Could be related to the seat heating or a specific function like seat position.

Porsche 986 Tombstone Seat Wiring (5 Pins):
• Brown (two wires in the same pin): These are likely ground wires.
• Red/Purple: This is likely the power wire, potentially for the seat’s motor or heating.
• Brown (heavier gauge): Another ground wire, likely for the heating system or the motor.
• Red (heavier gauge): This would be the positive power wire, typically for the seat motor or heating element.

General Wiring Suggestions:
• Ground wires (brown) should all be connected to a common ground point in the car, ensuring the seat frame is properly grounded.
• Power wires (red and red/purple) should be connected to the appropriate power source for seat adjustments or heating, depending on your seat’s features.
• If the seats have heating, make sure the heated seat function is wired to the appropriate power and control circuit.
• Since the connector under the Audi TT seat is different from the Porsche 986, you may need an adapter or to swap connectors to make sure everything matches up.

I hope this helps clarify things! If you’re still unsure, it might be useful to find a wiring diagram specific to your Audi TT or consult with an expert on wiring for custom seat installations.
