The ECM is beside the hydraulic pump.
You can get to it once you remove the relay bracket.
Is that your concern ?
If you search this topic it shows the relay bracket removed.
You have to go a long way down the topic to see the photos.
Convertible top cylinder ( ram )
I am guessing when you move the top operating switch on the centre console you do not even hear a relay click. From memory there is a multipin connector in the loom for the ECM.
If you have the wiring diagram you could pull it apart and check you have the two grounds you need and also the battery supply via the ignition switch.
You could defeat the neutral and handbrake switch by cutting into the wires just in front of the ECM and grounding them. Then you can operate the top anytime, and if you are sensible you will not do it at 60mph on the freeway.
If the ECM is fried and hard to replace you can bypass it and use Paul’s idea of simply controlling the top from switches on the console.
