I need to power seats outside of the car
Hi all,
for a project, I need to figure out how to power an E82 sport seat so that the controls of forward/back and seat back tilt work (don't care about any other controls). There are so many pins on the connector. Any idea where I apply +12v and ground? See below why I need this Thanks! |

Mate i checked the wiring diagram for power supply to the seat module, unfortunately the seat is on the CAN bus so just giving it power isn't going to make it work. You're going to need some kind of canbus emulator.
That being said, that's a really cool setup! |

bummer, everything on our cars is more complicated than it needs to be! Thanks for the suggestion, but I am hopeful that someone will by my pair of sports seats, so this is temporary. I would not want to hack the seat apart.

Get an arduino and can-bus shield if you're serious. Should take you a couple days of work to figure out what's going on and get it all programmed.
Also, try setting up that flight stick as an E-brake on the pitch axis. And get Assetto Corsa if you haven't already. It's by far the most realistic driving sim available on Steam, and as good as anything out there. |

just buy a recaro or other race type seat off craigslist and call it a day, this seems way more complicated than it could ever be worth.

I just got project cars, so might play with that for a while. I had read that the AI in Assetto Corsa was way too hard..

The AI sucks, the physics are much better than pcars. I like driving against other humans so I've only raced the AI a couple times and didn't find it challenging.

power to seats
If You have the same harness that I do,then You should have a red wire (power,hot ,positive +) and a brown wire (ground,negative,earth -) This should power all the electrical motors in the seat. Since the seats draw a lot of amperage .Remember the seats are fused at 30 amps . Connect the red output from Your power supply to the seat. Use an automotive inline fuse You will need a large regulated power supply.This changes Your AC house current to DC. You can get used ones on EBAY. You don't need one for clean power like the ones for sensitive electronics so it should be relatively inexpensive. Depending on the length of the run from power supply to seat You should use minimum 12 gauge wire 10 would be better.

power supply
Another twist would be to add a battery and trickle charge it.You can find industrial batteries,closed cell that are a couple of years old. These come out of backup power supplies for large mainframes. They usually switch these out every couple years for reliability. BTW, I have tried to move the seats using 6 amp 13.5 VDC and that was not enough. Good luck on a fun project!

No, I never really tried, too lazy lol. I will probably get my butt in gear to sell the two seats I have as a pair and then simply buy a race seat.
