Good to know, mine works since few days in continue but let’s make it more securely :
we replace the wires by resistors, as Tinkerman from espurna said : " resistor : anything in the range 180-680 ohms, 1/4 or 1/8 W will do. The advantage of using a resistor is that if you inadvertently solder the wrong pins, the resistor will prevent any damage to the semiconductors."
Then we isolate the en/decoder chip by cutting these lines :
The emitter at the back :
The receiver near the “RST” point :
Like that it should have a long life
