The convertible assembly you put in is actually from a salvage yard??? If so, did you take it off or did someone else??

Do you still have the old assembly???

When you put direct power to the motor the top goes up/down correct????

Once it's plugged into the car system it's just red light???

Here is step one: Pull all of the plug in's from the salvaged top, spray with Electrical contact cleaner both male/Female connectors. Now if you still have the old top look at the plugs in the old one and match them against the new top ....same amount of pin's?? no bent pin's in the new top. Using the old top look for any possibly damage to the new plugs.

Try the top again.... if nothing happens and it's red lights only.

Here's a little on how the top works:

The top in the car plugs into a white convertible controller. The convertible controller operates using 4 sensors, two of these sensors are on the front plate of the convertible top. These sensors tell the front motor to unlock the top when you push top down and to lock the top when you push top up. The other two sensors are located on the hinge lifter behind the driver (USA) model they basically are the on/off when the top goes up/down. There is one sensor on the top of the hinge lifter the other is on the side.

One or more of these sensors may have been knock off/ wire broken when the top was salvaged or when you mounted in your car. Follow the wire break out in the wire harness into the hinge lifter?? Are any of the sensors missing/lose or broken wire.
Rember you have the old top to use as a go-by to use in finding these sensors
Again, using the old top, follow the harness running to the front to find the two front sensors. Are they there, is a wire broken etc.

If any of the sensors are lose, missing, wire broken the top will not work and just flash red. The exact same as your reporting.

O/P I actually believe your issue is one of the sensors. However, you should check the plugs first just in case
