I am refurbishing a 76 450SEL and have some questions about three areas:

1. The lighter connection is missing and I want to install a new lighter (for a radar detector primarily) There is a loose wire near the parking brake on the left, with an inline fuse -- and I wonder if that is indeed the lighter power line. How can I tell or how can I otherwise hook up a new lighter unit?

2. The inside temp sensor is either missing (not visible in its pod in the current dash cove) or somewhere under the dash. Is this really necessary for the climate control system to function properly? How do I reconnect or connect a new sensor?

3. The original control stalk for turn signals, cruise, etc. was removed because it would not cancel out the turn signals after turning. The replacement stalk just handles turn signals well, but has no cruise control element. Also, when I push it forward for the high lights, the basic lights go out and the high lights do not come on. The actuating levers on this original unit have broken off, so that they do not come out of their opening .. which is apparently the problem with turn signal canceling that exists with that unit.
I want to repair it and put it back on the car... Can this unit be services; can I get the small levers that I need to replace to make it functional?
