What is this?

I'm redoing the enterior of my 1988 - 930 and this picture is of the hand brake assembly that is under the plastic cover. The part that I don't understand is this piece of linkage. Anybody know what it is? Or what it does?

That looks like the heater valve lever. If your car has the same heater control module over the ebrake that my '87 does then it is the heater valve control. It links up with a rod that has plastic heim joints on each end and moves back and forth as the cabin heat varies.

Yep,I think I have the same ebrake cover and it does connect as you indicated. But I can't manually move it and it didn't seem to do anything when I turned the heat contro knob, so I wasn't sure. MY guess now is that it is being controled by a heat sensor that I don't see, and that it must help control the amount of hot air that is being blown into the cabin.

Can anyone tell me what all the other "stuff" is that is located under the drivers seat? The pic is poor but if you have one of these and have ever removed the drivers seat, then I'm sure you can make it all out.

OK, the importance of this "stuff" has just greatly increased.

I'm 6'1" and I've always had a problem fitting in my 930. I can put the seat full back and my legs are ok but my helmet is always pressed so hard against the roof that I am always humped over just to see out. I've gotten used to it but it's really not all that comfortable. So, I want to cut the stock seat supports out and lower them by a couple of inches.

The problem that I face is that all this other electronic 'stuff' is under the drivers seat. Lowering the seat means moving the electronics that currently reside under it. What are all these 18-year-old technological goodies anyway and what the hell are they doing under my seat?

Should be a relay and fuel enrichment control i believe. It's the 'brain' for the O2 sensor. Others will chime in here.. but I'm almost 100% that's it.

If you can't manually move the lever it might be frozen down at the two heat control valves. If the heater control cover is off and there is nothing else connected to the arm, then you should be able to move it. If not then you need to go under your car and spray some lubricant on the two valves and free them up.

Also make sure there are no cable ties/tie wraps around the cables.

Yes that is the O2 control/cpu, fuel/rev limiter maybe power seat contrl. I'm 6'4" bolted my seat directly to floor and moved all that stuff on to a plexiglass sheet and bolted it where the rear seats used to be. I also put my msd box there.

Good deal, that's what I figured I'd do but it's good to hear someone else's approach.

Did you cut out, modify, and then weld back in the stock seat rail mounts or did you actually mount the seat directly to the floor?

BTW, did you lower the passenger seat too? (or do you even have one?)

I ended up sawsalling out seat rails and mounting steele frames under the car and the new seat mounts where the frames where sandwiching the body pan. I left the passenger seat frame stock so now my wife and I look eye to eye for a change. If you go back and look at my posts of my car ( looky what I have ) you will see the seat hieghts of driver/passenger. I also use the sparco three sided steering wheel to gain knee room. What ever you do DO NOT WELD NEAR THE TUNNEL !!!!! The gas lines ride on the drivers side and they will melt .

Well that's a really good tidbit of info to know... Thanks a bunch.

I just spent 2 hours staring at the remains of what is the interior of my car and I'm thinking that removing and recreating the mounts is just too much of a project right now. For the time I think that I'll just continue to drive without the bottom pad in my seat.

I'd sure like to see some interior pics of your car though, if you have any that you can upload.

my 'climate control' lever is frozen also, as PO had the set screw removed to the manual lever (77)
where are these referenced 2 valves?
I can get heat by manually moving the heat lever, so the flappers must be operating okay.
Thanks

Near the rear wheels.

Nathan is correct. They are just in front of the rear wheels up against the bottom of the car. You can spot them by looking for the two hoses that come off of the engine and go forward from the engine. The valves usually appear to be open and you can tell by the two little openings that look like the letter Delta. While you are under there squirt a little lubricant on the valves and cables.
