Only just seeing this thread now, fair play cracking into soldering the ecu.
I'm guessing one toggle switch is for an electric fan, but what about the other one? Always good to have the traction control button too!

Have a 325tds myself so already have the TD04 :-) Chipped aswel but still begging for more power, but off the road for the winter now sorting out issues like rust!

Toggle switch and the potentiometer are a fueling related mod, one which you can also do on your 325tds

Can't see why you need the switch aswell, unless the potentiometer doesn't go to zero? Yea, I've really got to pull my finger out and do this to mine, still haven't figured out which wires I need to splice into yet tho, but the plan is to leave it oem looking, using either the headlight level switch or dash dimming switch, which both fit in there neatly beside the tc
