Here's the previous threads regarding all of this - note that the recent change of server will make earlier posted links dead more than likely: ... hp?t=23725 ... hp?t=36733
Try the circuit in the 2nd link, as it is a pretty good implementation - I was wrong in that you have to stick to default resistor values to simulate the solenoids - I recently converted to a T5 manual, and in tricking the auto ECU with the solenoids, I used 120ohm 5 watt resistors , without problem - lower values will make the resistor get hot. You could experiment with higher values.

The solenoid uses 450mA of power so a 22 ohm resistor is a perfect substitute if you feel its necessary.

It will be emitting 6 watts of power so it will get very hot. I'd suggest two 10w resistors, a 10 and 12 ohm in series.

I would have thought that using too low a value will get the ECU thinking that maybe an internal coil short is starting to occur. Go too low and it may throw a 697.

O.k Bozz so i was right in saying that it's a low voltage sytem using only 450mA! I was originally concerned about even using the crusie on/off button as the surely the amperage would be higher in that circuit.....but have'nt had any probs with it so??? The 10 and 12 resi's in series sounds good .....but am i grounding these to chassis/ ECU earth screw and this is from the ECU output wire is'nt it so that when the ecu does send the sig out the resi's just use the power up and the ecu does'nt know any diff???
