What caddys have the thigh heaters? I need those! I can't stand sitting on a cold seat. It could be 90deg in the car, but if the seat is cold, I'm cold.

92-95 Seville or eldorado are the ones we are using. I think Bill grabbed some from a Deville, but they seem to have a lot of extra padding.

Here is basically what you are looking at when you go to remove the heating elements:

1993 Seville:


Basically, the elements are sewn to the back of the red outlined sections. Each piece of leather has an element sewn to it. Then the elements are sewn together. To remove them, you either want to cut carefully along those outer seams, or cut the leather on the outside sections from this. You'll want a utility knife with a new blade and this will go easy.
Wires come down where the blue dots are. The seats I got mine from both came down on the left side when sitting on them. Bill had them both on either the outer or inner sides of the seat.
The relay is located under the front of the seats as indicated. The wires have a few tie wraps and push-in holders under the seats and there is a connector that goes into the main harness that you can remove if you'd like. I suggest getting the whole harness if Possible as it makes wiring easier.
Switches are in the center console. There are three versions: Heated only, lumbar only, and both. Bill and I have the Both. I'll be getting a heated only soon though.

Hope this helps people. If you manage to get them, I can make the wiring diagram available. Again, 92-95 is what this is for.

Hey Geoff
Your help would be greatly appreciated. A meet would be cool. I'm going to the yard on tues, and I will hopefully pick up the parts that are needed. Your coded diagram really helps! I'll get the parts and we'll go from there. I'll PM you and hopefully we can figure out somthing soon.

No problem at all. I figured someone could use the diagram. As for cutting, I'd suggest not cutting at the seam when removing from the car. It will make for a little extra work later on, but worth it so you don't accidentally cut the heating element. If the car has a good battery, or if there is a good one somewhere in the yard, you might want to hook it up to the car and test the seats before you remove them. Unfortunately, they don't leave them in here usually, so I couldn't. I have a computer power supply that Rob and I used to test them with.

We can work out a weekend that works for both us, possibly the last weekend in January. I'm sure Rob'll come as well since he can legally drink there.

Geoff...great info and pic.

To clarify I have only ever found the wires on the RIGHT side of the seats. And when cutting the bottom cushion, the wider the berth around the bottom of the seat the better for pulling the cushion out and not having to try and dig under the seat. Instead you can work through the seat.

Great diagram, thanks! How is the thigh heater going to fit in the SSEi seats? You can't trim the heating elements...

Not "how", but rather "how well" will they fit?

They fit awesome.. I have pics up at the beginning of this thread.

I don't see where you put in the thigh heater, did you?
