Recaro ergomed ds electrical connection

[pashka24]

Hey guys,
A little update:
Today managed to wire the loom to the seats. Loom went from seats to the center console under the carpet and will go under the dash. Installed the seats so the only thing i have to do is connect the wires. Now, ground - no questions. +12V i need to work when ignition is on. Can someone tell me to which relay in auxiliary panel i should connect it? I am guessing a power/work relay with 4 pins should work? I have a manual for coupe 1990<, but info there does not correspond to what i have:

Back side:


Can someone please direct me here? To where should i connect it?

And of course, the seats

Hope it is ok that the fuse is at the end of the loom. Used 20A fuse. Should i go with 30A instead?




Thank you in advance

Seat motors usually work with ignition off (unless buttons are illuminated?)
You can find a large spade connector on the bottom of the fuse box which is up behind that relay panel.
The fuse should be as near as possible to the fuse box to protect the wiring under the carpet!

I am not sure but i think buttons are illuminated. ****, i have to take off all that spider web? but then i have constant power, and i need power when ignition is on. What else can you suggest?

So you say the location of my fuses is bad? I should relocate them under the dash? I will have to amp up to 30A :/

You don't have to take off the spider web get a cushion and a torch and lay on your back where the seat will be, get your head right under the dash and look upwards.
Have a look to see if you have a spare big spade connector on the bottom of the fuse box which is on the 30a feed, I don't know if there is one which is switched..
If not then add a relay to the panel and trigger it from a switched feed.
So with an ordinary simple relay..
30A unswitched power
Spade to 30A fuse
Fuse to relay pin 30
Relay pin 87 to seats
(All nice thick 30A wire)

Switched power to relay 86
Relay 85 to ground.
(Thinner wire is ok)

Bottom of fuse box looks like this, area L has a bunch of 30A feeds

Some of the other areas will have switched feeds.

Where can i get switched feed from if there is no switched power at the fuse box?

Ok, connection 75s under are M is switched power. Great! Thanks a lot, this was helpful!

Last question, i used from seats to relay 2,5mm2 tinned wires. Now when you said the cables must be thick, i am thinking that for 30A i will need gage 10 cable which is 5,5mm2 that is really big. On the fuse its written max 30A and cable is the same as i am using 2,5mm2. I am confused, should i change the cable or go with 2,5mm2? Dont want to go in flames...

I'm pretty sure 2.5mmsq will be ok, it's not like you're running the motors all the time.

ok, I will see if I can scout our bigger cables. Just need to relocate the fuses soldered everything perfectly and now need to cut everything again... stupid me

But Thanks for the input! very appreciated!

So yesterday i wired everything up, seems to work well, only thing one motor is not working correctly, when i click the button it seams to engage but does not move an anything... found switched power supply at the bottom of the fuse box so i didn't put any relays. Used 2x20A fuses, one for each seat. All in all i am happy man seats are really nice and very comfy next step, reupholstery in summer, in red/ Bordeaux color thanks for the input guys
