How to retrofit/ make your own loom for heated electric seats

That's a fantastic write-up!

I wish it had existed when I fitted heated/electric seats to my car, as I went down the 'take a damn loom out of a donor car' route...

I can confirm that it's a complete pain & seemed to need most of the interior & dash removing... I ended up modifying my colossal loom anyway, to make re-installation easier.

Also, I didn't fancy a stuck seat-switch flattening the battery or starting a fire...

So I ran the live feed from a 12v supply that comes on with the ignition.

Questions:

Anyway, my seats are the non-memory type.

If I wanted to fit a memory driver's seat, would I need to convert the system so that it's always on, with a permeant live supply?

I would assume that the memory bit needs a permanent live, or is that taken care of by the K Bus link? (I'd guess not, as it seem the K Bus link wire is optional).

Would the memory be retained if just the memory part had a permanent live?
