How do I take out the back seat w126?
 

Planning to run a bunch of wires to and from the trunk for some nutty modifications I'm planning... I have the seat bottom out but the back doesn't seem to come off very easily...
Once the bottom was of I saw the rail that slides the whole assembly back and forth and disconnected the seat heater things... but i still can seem to get the back off

I'm sure there has to be something toward the top of the seat back that I'm not seeing from underneith... Please help... Thanks in advance for your guidance...

Have a great day.

There are a few fasteners on the bottom to remove then just lift the whole seatback up. There are clips at the top that fit into slots.

I think i found what was holding me down... because it's a moving electric seat, it has a few pivioting things near the top... i'm tring to get them apart only because it looks like it was made to come apart...

Got it!
 

After disconnecting the two 10mm bolts from the slider on the bottom i had to pop out two hard to reach pins near the top of each side of the back back... Once those were out... I untangled the seat belts and it was out!
