The bolts ( 5 ) are unscrewed.
The new motor ( 6 ) is bolted on.
The IR source cables ( 3 ) are then soldered to the plug ( 1 ).

Due to the high current for the IR sources, the solder joints must be very well made.
Inside the plug ( 1 ) two pins are soldered together to form one connecting point.
Two such connecting points are present in the plug ( 1 ). Each of the two cables ( 3 )
are soldered to each connecting point. Polarity is irrelevant.
