The turn signal switch will turn the brake light off on which ever side the turn signal is on. It's controlled by the turn signal switch. This is normal. The alternator coming on isn't though.

Look at the fuses and make sure they all are good and working when power is on. These trucks are bad about the fuses getting rusty and not making contact even in the holders correctly.
As far as the wiring problems that a personal choice.
Here is a link that shows the correct color wiring. You can figure the wires out from here.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
