Default 2000 SSEi Bonneville Seat wiring

Hello All,

I am a new member to the site and this is my first posting. I have inherited a beautiful set of 2000 bonny SSEi seats (fronts and rears) that i am fitting in a 69 chevelle. The back seat is already in and fitted and i am not on the front seats. Here is the question, these seats are power and heated but all i have is the seats. Do i need some other module or something or can i just power these seats directly? I am guessing i would need something to turn on the heating elements......which may be why i need the module or controller or something? I don't really need the heaters to work, but i would like to get all of the power functions operating. If i need a module, is it something i can purchase from a dealer or do i need to hunt the boneyards? thanks in advance for the answers.I am sure i will have additional questions.

You should be able to find a control panel at a scrap yard. You want the one that'* in the center councle That way you have all the switches. Then you just need to wire it all up.

Does anyone have a picture of the control panel that Dan referenced above? Once i have the control panel, then how do I power the entire thing....or once i have the panel will it be self explanatory?

Dan is incorrect, the 2000+ seats have all the controlls on the side of the seats. There is a Memory function on the drivers side, but that does not need to be used.

IIRC all you need is the power and the ground to make the lumbar and the seat movements work.

The heating elements are powered very differently, still doable if you have a rear integration module that you could splice in

Actually, a Rear Integration Module (RIM) is not required to make the heated seats work (although you do require switches and some miscellaneous wiring). If you don't have the RIM, the car won't cycle or shut down the heated seats if the battery or alternator voltage drops significantly. A RIM installed discretely would not function in the manner intended because it receives the message from another module (that you won't have) to command the RIM to shut the seats down.

I have personally connected heated seats without the heated seat status and inhibit signals attached (at the RIM) and everything functioned otherwise as designed.

As 1993 SLE says, you should only require a fairly heavy guage positive and ground. There would be no way for you to make the memory option work. This also integrates with all the other Bonneville body control modules.

Thanks for your responses 1993SLE and DDAlder.......i am very appreciative. My question though......in light of your information is......what wires do i connect the 12v power to? My seat has two connectors underneath. One is a large connector with maybe 20 to 22 positions (with only about 12 pins installed) and a second 2 position connector. The larger connector does have a larger gauge and a smaller gauge orange wire.....are either of these the positive input? And there might be a large ring under one of the seat mounts that could be a chassis ground, or do i need a ground to one of the wires in that large connector? Also, what is the two position plug for? Ugh!!!

I'll pull out the manual, but it may not be until later today or tomorrow. I've got a crazy day lined up.

You should be able to power the seats without a module. As for the ground, it will be provided through one of those connectors. In the Bonneville, GM wires almost every ground through splice packs that are bolted to the body in various locations.

The passenger seat should be fairly straight forward.

The large connector you refer to should have 18 cavities.

Pin A4 - ORN - Battery Positive Voltage
Pin B6 - BLK - Ground

The cavity identifiers will be embossed in the plastic.

If the two cavity connector you are referring to is YELLOW, this is for the side impact airbag. DO NOT apply voltage to this connector.

Now, as for the driver side, this gets a lot more complicated. This is because you may need to eliminate the memory seat module from the circuit. I would try without doing this to start.

Again, you should have an 18 cavity connector.

The main power connection and ground are the same as the passenger seat shown above.
