Lumbar??
Re: Lumbar??
IIRC it exits the seat back at the right (inside) bottom corner, near the hinge-point. I just redid the seats in my Yellow Indy last year too, so I should remember
... My air-bladder was toast though, so mine doesn't have that anymore, but I'm pretty sure that is where it is supposed to be. You may have to unzip the seat-cover and dig some if your line isn't exposed anymore.
