Heated seats

[FredMrBX]

Hello everybody,

I found front heated seats from a Swedish bx with the original loom.

Does anybody know where I can connect them on my bx please? on the 12V accessories connector on the back of the central console? or the rear electrical windows switch?

I've made a schema of the loom I have:



The brown connectors on the right are to connect on the seats.

Thanks
fred

I'd have thought there would be quite a current draw on them so you wouldn't want any piddly little wires. The 12v feed to the accessories socket is quite thick wire (for a BX anyway!) and seems like a reasonable option. Personally I'd be tempted to run a fresh, fused 12v feed either direct from the battery or fuse box.

I would assume the right connector between the brown seat connectors should be the - Negative?

I believe the convention on the BX is to switch things to earth such as the rad fans, interior lights etc so more likely that it would be + and the other side of the switches taken to the negative.

Don't suppose it would actually matter which way round would it?

It would if there was some kind of semi-conductor control built into the pad to guard against overheat as that would then 'pop' on a reversed connection. I don't know the type of pad - do you know this to be purely resistive without control that you risk BBQing your bum if left on for a journey on a cold day?

Is the little nobble on his drawing not a thermistor?
