Well, Ive done it, the hard part, fitting the cooling back plate, the temp sensor (for auto temp regulation), removed the front filter and modified the sensor circuit for amp off.

And hey, after it was all reassembled, I fired the cam up and it worked . Yippy !!!!! (that part was a worry, cutting and soldering the sensor pins was tricky, I must say).
The rest is easy, all external.
