I have got a "doozy" for you guys! I have an 03 Chevy with the driver's side 6-way power bucket seat which DOES NOT have an adjustable lumbar support. My goal here is swap parts from a bucket seat model that does have an adjustable lumbar support into my seat. I have exploded diagrams (from gm parts department) of my seat, an 03 seat with electric lumbar, and an 02 seat with manual lumbar. I am trying to collect the numbers on the diagrams that I will need to create a complete parts list. So far on both diagrams I can see the lumbar support and the exterior plate and knob/control that I will need to retrofit. However, I cannot figure what the part number is that connects the knobs to the lumbar assembly. Can one of you guys help out?

Here are the diagrams I am looking at:

My truck:

Make: light truck, year: 03, model: escalade/model 06 4 x 2/models 03,43,53
tc16-774 01/23/2003

The electric lumbar:

Make: light truck, year: 03, model: escalade/model 06 4 x 2/models 03,43,53
tc16-770 01/23/2003

The manual lumbar:

Make: light truck, year: 02, model: escalade/model 06 4 x 2
tc16-698


Thanks guys! :ro)
