Hi everyone,
So I'm not really technical with circuitry only what I've picked up along the way. I'm just a heating technician, mainly fault finding at its most basic form on electrics, voltage tracing etc.
So basically I want to install a remote start on my van and need to temporally disable the clutch sensor so the PCM thinks I have depressed the clutch. (I know what you are going to say....that's dangerous.) But my remote starter has other built in safety devices like neutral detection to stop it being started when in gear.
Unfortunately I have the hall sensor on my clutch system which senses the exact position of the clutch, it has 4 wires. As apposed tho the older cars that is just a 2 wire switch.
The wires for the senser are as follows:
How do I simulate the fully depressed action? Remember it's only temp, the remote starter initiates the trigger only on crank via a negative feed for a few seconds then a relay breaks the connection.
I've connected most of the wires via the gateway can/bus connections of the van. The clutch bypass wire from the R-starter would normally ground to the simple on off switch temporarily to bypass the clutch but obviously this setup won't work for the hall sensor. I think I can work it so I have a positive signal wire from the RS to the hall sensor if needed?
I wondered if I could just use a link from the 5v reference voltage supply using a diode plus a resistor to bring the voltage down a bit to the cpp2 to stimulate the 3-4v but i haven't tried it yet... thought I would speak to someone who knows more before I blow something up.
Heres the schematics for the sensor....

Basically my question is which wire would I need to alter to achieve the trigger voltage, which I'm guessing is from 2.6v-4.8v on the cpp2 control wire ?? Do I need to add a resistor in there somewhere to bring the voltage down on the VREF (I have no idea really, this is what I've heard others doing but not sure it applies to my setup ) Or can I just link the VREF voltage straight to the cpp2 wire to give 5v?? Please help asap as this is the last step to completing the system. Thanks in advance. Chris

The wires for the senser are as follows:
- Cpp1- which is clutch pos at the top( I believe)
- cpp2- clutch pos bottom fully depressed.
- Signal wire which I believe is ground to pcm
- Vref voltage which is 5v DC shared with AC system.
