I got my bits from a member (who seems to not be there any more) on "The Other Side"
He supplied the ECU
for Ã‚Â£47, and threw in the mounting bracket, centre switch, and a four hole switch panel, complete with two heated seat switches and an electric blind switch! I have since bought a three hole panel (as my car is a Tourer) and sold the blind switch. If I can sell on the four hole panel, my original two hole panel and the two seat switches, the total will be more or less nothing!
I already had a steering wheel with switches btw, and all the wiring etc was already in place. BigRuss did me a T4
which gave me full functionality!
