Things You'll Need:
- Ladder
- Pliers
- Wire strippers
- Garage opener
-
Step 1
Shut off the electricity to the house before working on any electrical project.
-
Step 2
Rope the wires around themselves and attach them to the ceiling of the garage until you've come to the motor head that is hanging from the ceiling near the rails that the door slides open and closed on.
-
Step 3
Take off the rubber insulation from the ends of the wires so you can twist them together and have a solid electrical contact. Wire strippers will do the trick easily. You can also use a knife, but be careful that you don't cut right through the wire and make it too short to reach the motor head.
-
Step 4
Match the wires from the motor head and the wires you've run across the ceiling from the eye beams to each other. Pair them up by what they look like. A red wire with the red. One with a black stripe goes with the other with a black stripe, running down its length.
-
Step 5
Twist the exposed ends of the matched wires together with a pair of pliers. Each wire will have a match that needs to go together.
-
Step 6
Find the little holes on the motor head for each set of wires to plug in to. Every garage door manufacturer is different so it is important that you look at the instructions the motor head came with to know exactly which set of wires go into which hole.
-
Step 7
Plug the wires into the motor head's receptacle holes. Once you've identified the right holes, the wires, twisted together, can be pushed right in and locked down. Be sure to leave a little slack in the wire in case you need to go back later and readjust something.
