Under the carpet at the hump for the front bolts there is a black, plastic sleeve containg four pairs of wires. They lead from the switch to a plug on the bottom of your seat. If you cannot get to the plug with the seat in its current position' you can strip back the black sleeve to reveal the 4 pairs. Each pair is individually wrapped so be sure not to remove the individual wrappings or you'll have a hell of a time matching them back up. If you can get to the plug; pop off the cap and pull out the wires...making note of their position, of course. The pins are soldered to the wires and make a nice chunk to apply power to. There are two more much smaller plugs that control the "key off, door open, seat on" feature. Leave them be until you get the bolts out then unplug them. Note: the power seats are heavy and awkward to hold on to.

The blue/purple pair moves the seat forward and backwards. You will also need to tilt the rear all the way up to get to the rear bolts which will still be a pain but ultimately possible. The orange/gray pair will do this for you.

You can use a 12v battery from a power tool if you have one. This will make the whole process at least one magnitude more pleasant. Reverse the polarity to perform the alternate movements.

The wire colors are from memory so if I botched a pair or two you can't hurt anything. You'll figure out which pair does what quickly enough. Keep your hand out from under the seat at all times. These MB power seat mechanisms are insanely strong. Severing a finger wouldn't even slow the motor down. Taking off a hand may cause it to breifly strain at best.

Good luck.
