Detailed instructions for fitting Mazda RX8 seats needed

Not ideal apparently and it's permanently live, the seat adjuster catches the door card sometimes and moves on its own!

MIne don't touch the door, close but a couple of mm spare. I have to have the door open to move it though. I shoved a relay onto each seat and wired the heating and the movement all to the same switch that also is attached to the ignition. Works well.

i don't have much wire showing for what I think is the heated wires, you got a pic of yours?

It doesn't help you, but I was lucky enough to get all the connectors, those on the seat loom plus those that came from the car

My buttons are clear by about half a gnats pube. Mine are all round stubby like buttons so think possibly the actual buttons are lost. Another reason I wired everything to a switch, just in case the buttons did foul the door

Hi Mate,
Huffhuff has a really good outline of the wiring check his threads out, that's where I got my information from.

Here you go Mate try and expose some wire and use this guide below to work out which is which. One thing I did suss out with these seats is that they go so far forward that you don't need to remove the seat base to access the boxes beneath for battery and jack etc.


Seat Motion
Grey - +12v
Purple - Ground

Lumbar
Yellow w/red stripe - +12v
White w/yellow stripe Ground

Seat Heater
Blue - +12v

Passenger seat
Seat heater
Red +12v
Black - ground

Heated seats work, 12v is 12v, just have a on off switch in line so they do not burn out

Really? I've not actually tried. I took delivery of a new hankook battery yesterday (preparing for snowmageddon) so will try that method today.

Actually, thinking about it, I mounted the rx8 rails onto the original seat rails. So, in theory I have double the length to play with. I think I can probably get to the battery without removing the seat too. I'll give it a go in a bit

What's wrong with putting the wiring string to the battery with an online fuse?

Thats how i did mine but used seperate fuses for each motion

My Mate owns Cornish Rattler by the way. Where in Kernow are you? I'm SE near Looe.

Although you can get to the terminals perfectly well I'm not sure there's enough gap to remove the batt though.

Incidentally what size fuses did you use?

I wired mine into the fag lighter in the dash. blew the 7.5amp fuse after 1 use so switched it out to a 20 amp. been great ever since.
Had to make shift all new brackets though. think only 1 original hole on both chairs fit the original landy holes ha

So, no relays or any of that crap? Have a look at my thread for fitting, I managed to line up the holes onto the Mud seat rail extensions and only had to drill the rear holes in . I'm well chuffed with them.

no mate, no relays. relays just stop it drawing power when the engines off. my fag lighter doesnt power unless its turned over so its all ok

Oh at last somebody can explain in a few words what a relay does. Well relays can sod off then and I'll piggy back my seat switches onto an ignition live.

Well relays stop you setting your car on fire ( if you wire it all in correctly)!
Is that few enough words?

No, actually. There's a few people on here that have wired them direct ignition with a decent inline fuse and they haven't burst into flames yet.

Yet.

A couple of months in one of them and no snags. If it was going to burn would it not have gone up by now?
