It's an issue with the microswitch most likely. And probably not electrical, but a matter of getting it lined up properly so it will make contact with the retracting top frame and trip at the required point in the operation cycle.
There are
3 microswitches for the convertible top:
- 1. Microswitch, convertible-top lock
2. Microswitch, left B-pillar
3. Microswitch, convertible-top compartment lid
#1 is the switch in the Latch on the windshield header - this one isn't the problem, when it malfunctions, it prevents the motor from starting and the top from opening.
#2 could be the problem - it can get dirt and debris in it preventing it from closing - check to see that it operates freely. Remove any dirt or dust carefully with a pick and some compressed air.
#3 is the most likely to be causing your problems. It is part of the motor bracket. My suspicion is that when replacing the cables, either the connector became loose, or when reinstalled, it was not lined up correctly and the trip arm is not being engaged.
