At my local Aldi you can buy a heated seat thing which plugs into a lighter socket. I bought one for my mg. £8.95. works brilliantly, takes 30 seconds to fit.
Haven't tried it in the mog as the heater is so good.

Had a set put in when I had my seats retrimmed - there were about £40 from eBay.

I have an old trad, so I made some brackets and fitted the switches either side of the heater I also fitted myself.

Very neat

Many thanks for your tips and advice, I have fitted the pads to one seat, I had to remove some c clips to get the cover off slightly so I could get the pad in place. it’s the tombstone recliner so might be different for others.

Now just needs to wire it in. Any recommendations for a easy switched supply one could piggy back off?

Many thanks,
Will

Will, which model & year ?

Many thanks

Try any green wire from the fuse box. Most if not all are fed by the ignition switch. I believe fuse 15 feeds the heater fan switch on such a green wire and may be convenient. What ever fused circuit you use, ensure the rating is upped to cover the extra load. I don't think the seat pads take much so an extra 5 amps on fuse rating should suffice.

Hello Will,
I have retrofitted heated seats in a 93 plus8. Some fuses have battery voltage, others have ignition voltage. So be careful! I used Lucas 2-stage toggle switches and switched the battery voltage via a relay. If you want, send me your mobile number personally, then we can call via WhatsApp.

Sorry for my bad English but school is out since many years

Günter, many thanks Will PM you.

I have taken a feed off the Green / Slate wire from the heater switch so the heated seats go on / off with the heater. Which makes it convenient, my only thought is there being enough power for both..

Received my pads yesterday. Thought I may as well fit them because I new I'd have to remove the seats to get the tunnel off to renew the rotoflex coupling, will do the webbing at the same time.
A quick check of the wiring diagram shows the switched feeds are white and green or white on my car so will use one of those to control a relay with power coming from a suitable supply, maybe the 50a circuit to a new auxy fuse box.
