The control unit seems to be located on the bulkhead in the engine bay, in between the expansion tank and the fuel filter.
It has a large red + feed wire, and two multiplugs. one multiplug has 4 wires, one to each glowplug (5 on a 2.4) and the other connector has the data and supply line for the control unit electronics
I'm pretty impressed overall with the conectors used on the 159 but reseating them won't cause any harm and might help resolve a problem or two. The units themselves seem to have a problem with a sticking relay inside.
Part number is 55193073 I don't want to take mine apart unless it's giving me a fault, but I would look to repairing or replacing the relay.
There seems to be a lot of suitable candidates on eBay at £30-£40...handy to know
