There is acutally an easier way to do that, instead of having to yank off the upper manifolds tap a hole and all that. If you unscrew the IMRC box, the motor is exposed, then all you have to do is attach to wires to motor and connect that to a light.
When ever the motor open it will come on and the light will stay on until the motor is denergized. The ECU sends 12V to open the motor, then once it detects thats its open it lowers the voltage to hold them open. Even with the lower voltage a LED should stay on, or you can use a small incandecent bulb.
The idea of mounting it on the actautor cam is that it will only come on when the butterflies move, if the IMRC cable snaps, gears shear etc. I will know. Taking the signal from the IMRC electronics will not tell you this. Also, this can be used on the early vacuum controlled inlets
I will have to see how the temp side goes, but I am not overly concerned. The senor is not mounted directly on any hot surfaces, I should imagine it will be operating near it's maximum.
