The organge wire should have power at all times via the stop / haz fuse in the fuse block. I believe it is the lower left fuse. The white wire from the switch goes into the curved connector on the steering column. In the steering column it is connected to the hazard switch. Basically the hazard switch connects the brake / haz lights to either the brake switch or the hazard flasher circuit. It does not connect to the turn signal switch.
So it sounds like you've narrowed the problem down to having no power on the orange wire. So lets focus there. The right hand terminal of the stop / haz fuse should connect directly to the orange wire on the brake switch and one of the (bottom terminal I think) hazard flasher terminals on the fuse block. If that works then see if you have 12 volts on the left hand terminal of the stop / haz fuse. You should have power there. That is fed via a fat red wire that provides battery power to all sorts of circuits in the car. If not, post back and we'll take it from there.
Be watchful of bad connections such as those caused by corroded terminals. The fuse terminals are a prime suspect. What is weird about bad connections in a relatively high current circuit (such as the tail lamps) is that they'll show full system voltage at no load and next to nothing when loaded. If you need to remove some scrunge from the fuse terminals get a small round wire brush like a .22 caliber rifle barrel brush to scuff them up again. WARNING - disconnect one of the battery cables (negative recommended) before sticking metal objects in fuse sockets. [img]graemlins/clonk.gif[/img]
Let us know how it goes.
