Gentlemen,
I've just made my acquaintance to the Aurora, while looking for something for my truck. While at the local Pick-a-Part car lot, I was walking pass an nice looking
01 Aurora that happened to be missing the driver side doors, and the leather seats caught my eye. They are in near perfect condition,(doors must of just been removed)
with no blemishes at all, and for $10 a seat, I bought both front seats. I am in the process of restoring a 90 F-150, and like to install these seats to replace the old
bench seat of the truck.
I was able to acquire a parcel wiring diagram for the Aurora's seats, thinking I could bypass some the major computer connections, and wire them up more simplified,
more directly to 12v power source. Apparently that's not to be, after making a what I thought to be a simple connection I blew out the driver's seat side air bag.
After finding this site and reading thru some the threads, I'm finding that the Aurora's electrical system is quite complicated. I noted the large blue and smaller black modules under the driver's seat and there's none under the passengers seat.
Before I proceed any farther, possible more damage, I hoping that someone here has some experience working with the electrical system on the seats, and bypassing the
all the computer and sensors requirements in order for them to work. They are in too great of condition to be left out to rot in a junk yard.
Any help in solving this problem is greatly appreciated.
Many Thanks...best regards.

Blew the airbag, huh? Hope no one was hurt...
I can get you any/all wiring diagrams and plug pinouts you need. I'm thinking you may be able to retain all functions except memory. What exactly do you want to keep/delete? Is lumbar a big deal? Heated seats?

tigger,
first I'd like to thank you for your quick reply and your willingness to share your expertise: second, no one hurt in exploding the airbag, seat was sitting
on work bench when I connected wrong wire to battery.
After I removed the seats, I cut the wire harness from the "car" about 10" before the connector to the seat, so I have a black female connector with
about 17 wires(there is also a lead with a yellow connector with 2 wires) that plugs into the blue male connector on the wire harness of the seat.
I'm not concerned about the memory, as I'm probably the only to be driving the truck, however having the lumbar and heat working would be the icing on
this project cake...but not mandatory.
What ever actions that will work beyond the back and forward would be greatly appreciated, as I tilted the seats a bit while still powered up in the car to
help remove them.
I really appreciate this help, greatly, as I would have hated to been able to use these seats.
Best regards...
Dave

Here's the pinout for the seat connector. 12V to A4 and B5 with ground at B6 should get you movement and lumbar support. I'll have to get back to you about heated seats... Good luck! Gotta go cook ribs! Happy Labor Day!  |

Tigger ...."You the Man". I'm very grateful for the diagrams, will have to try out the connections, see what's working.
I'll keep you posted on my progress or the lack there of.
On a different note, I see you've a 01, which is what the seats came out of: the car looked in really good condition with only a small
dent in the front fender so I ask the personnel of the junk yard what was wrong with the car. Their computer list only showed
to check engine and check transmission. I had a local GM mechanic tell me that its very expensive to replace the engine or the
transmission, have you had much trouble with your 01?
You're a good guy. Hope the ribs came out alright and you had a good labor Day .
Many thanks....

No problem, Dave! More than happy to help. Gonna have to ask for some before/after pics though, haha. I think everyone around here will get a kick out of seeing Olds seats in a resto Ford pickup...

Actually, I've been pretty lucky, or my OCD is finally paying off. A couple failed sensors, leaky hoses, and burnt interior lights. Other than that, just maintenance stuff... (Knock wood!!!) P.S. Ribs were great, beer was cold... Life was good today! |

Hey Tigger...Nothing better then ribs and beer. Can do on the pics, be glad to....
Now for the dumb question of the day...the blue and black modules under the drivers seat, what's
their functions....guessing they must be connected for the drive motors to work?
really appreciate all the help
Dave

Sorry I didn't see your post earlier, would have taken a peak at mine, lol...
The only 2 that come to mind are the memory module and the heated seat module. Can you post me a pic?
Anyway, the memory module would be the larger one, and yes, all motor functions run through it so it needs to be connected. It uses the same power and ground as the seat adjuster switch, don't see a problem unless it has to communicate with the PCM. I'll dig into the service manual...
If that is the case, I still feel confident that the seat adjuster switch can be "straight-wired" to at least give you seat movement.
Hang in there, we'll get it...

Man, those seats are in really good shape!
Yeah, the blue one is the seat adjuster memory module and the black one is the seat heater module.
I haven't cracked open the service manuals yet, any luck on your end?

Good shape indeed...too good to pass by and for $10 couldn't go wrong...if I can get the drive motor wiring figured out...lol.
I've not cleaned or used any leather conditioner yet which will make them even better looking.
I've not had the time yet to reassemble the driver seat, too busy with everything else that the day throws at me but have the weekend to
do it and try out the connections.
I see there's no black heater control box for the passenger seat, which is OK. Let me know what you figure out from the manual, if there's
gonna be a problem with the power going thru the blue memory control box....when ever you've the time.
I'm still dismantling the truck, and cleaning the shop to do the painting in.
Many thanks Tigger.

Well, looks like the memory module does indeed use serial data to communicate with EVERY other module in the car, haha! It's useless to you, chuck it, sell on Ebay or something... So get your wire cutters and soldering iron ready... Hacked harness time! Here are the direct connection diagrams. Apparently, there were Auroras without memory or heated seats!  Save your heater module though, think I can make that work... Driver  Passenger  Lumbar  Let me know if you need anything else... |

Well...if figures...about the memory box...from what I've read in the forum here., the electrical system seems fairly complicated.
Gonna get the scalpel out, start the surgery on the harness, I didn't think it was gonna be easy after I blew the airbag. lol
Really am thankful for the diagrams, now I at least have a starting point(s) to cut.
You're a good guy, Tigger, owe you a beer or more...I'd buy ya one if I lived closer...am in central Indiana.
I'll send the memory box to you if you you'd like, contact me at .... lincoln642@hotmail.com
Greatly appreciate all the kind help. I'll keep ya posted on the progress.
Have a good weekend, take care.
Dave

Haha, thanks bud! That's way better than what I'm usually called. Like I said, glad to help.
Gotta pass on the module though. One more part in the garage and Mrs Tigger might blow a gasket!
Good luck with the "surgery"...
