Yowza, thats a hard post to read.
Double cab Pre-Runner (2WD) that you are doing an SAS and 4wd conversion on... you need to shut off the airbags when in low. RIGHT?
I would say remove the fuse or use a couple spade clips and inline fuse with a switch in the middle so you can turn it on or off, although this might not work in all cars.
I know my honda (totally unrelated I know) I have to go through a whole re-set procedure for my airbags if I were to do that.
