Drivers seat mount: as a quick fix, I broke the welding apart, reduced the slot, welded it back together and installed. Sloppiness is still there, but quite a bit less.

Plugged the green connector from car into green of seat.
Need to figure out what other connectors are for, and if the installed seat is heated.

 

Here are photos of the passenger side seat. One connector (green) is plugged in. No other wires/connectors coming from car. One connector (black, 2 wire) is connected, one connector (black with green, spade) from the seat is not connected.

a) is seat heated?
b) should there be more wires from coming from the car?
c) is the seat rail running 'metal on metal'? I expected to see a teflon or plastic insert (less friction).

 

Im thinking its this also on the pass side but looking at the pics. of the drivers side id say who knows.

 

How is the plastic piece called?
How does it look like?

 

Here's where the plastic piece is suppose to be ... I tried to take a picture but it wasn't clear enought to post it ... I would have to remove the front the seat to take a clear picture ... I have no idea how you call that part ... I'll will try to remove my seat this week so I can take a clear picture

 

Thanks for your effort!

 

I tought I can post the picture I took even if they are not really clear ... maybe it can help you ... and by the way, it's more of a rubber piece then plastic.

 

Just as a data point, if you grease the contact points of this plastic thingy, it would allow the seat to slide back and forth MUCH easier. I just did mine after suffering through needing to get out of the car to adjust the seat forward for many years...

 

Use white lithium grease for all moving parts, including rail, pin, spring, lever.
I am still looking for the plastic insert for both sides. This would at least put the passenger side seat decent shape (currently moving quite a bit and requires 'wiggling' to get let the pin snap in. Couple of times, the passenger moved all the way forward with this heat under hard braking).

The driver side will need the plastic. Wish I could get my hands on the factory parts (not the butchered bracket). But with the plastic, also the driver seat will be more fixed (the play it currently has is irritating).

But most important: since seats were apparently changed by previous owners, and not the correct ones used, I still have not figured out which connectors go where, including heated seats not working and airbag warning light on.

 

This is the part that you are looking for.
