If you have an "integrated" turn signal stat you will be just fine. What is an integrated turn signal stat? It will have 7 wires. integrated means the turn signals are integrated with the brake lights. A good Tech Tip is here:
http://www.stovebolt.com/techtips/turn_signal.htm The lower set of wire lists is the one you want. The Brake lights are the turn signals and the big filament in the light bulb is the brake/signal light. The smaller filament is the tail light. An 1157 bulb has 2 contacts and that is how they work. The bigger filament is the bright one. The lights you have look like accessory lights and if there is a trailer parts place close you may be able to get lenses there. A note: New lenses are plastic. This is not a bad thing(they are cheap) glass lens will be more expensive to replace. Not as complicated as it sounds.
The fuel sender has a post for the wire to the gauge. The second wire is the ground. If you have a stock tank you can pull the sender out and verify which is to the sender with an ohm meter($5 at Harbor Freight) It should read 30 ohms when it is all the way to one side and 0 when it is all the way to the other. Just move the float up and down. Disconnect the battery and hook up by the instructions. Use a charger to test as you go. It won't melt wire as fast if there is an issue. Take care and take your time it will work.
