These are for NEGATIVELY Earthed Vehicles

(they may vary according to vehicle type and are for controlling the vehicles Starting Solenoid -
G-Spot's can also be used in conjunction with relay(s) for controlling other essential functions)

    Pop the vehicles hood/bonnet or boot/trunk.

    Locate the battery and follow the largest cable from the batteries +ve terminal to the vehicles starting solenoid.

    Disconnect one of the thinner wires at a time (if more than one) from the starting solenoid until turning the key doesn't turn motor over.

    This is the wire you need to interrupt with your G-Spot.  Trace it to a point where it is far enough away from the engine heat and cut it - it can be under the hood/bonnet or under the dash in the passenger compartment. 

Note:  If you have doubts about your ability to install this, I encourage you to err on the side of caution.   You may void your warranty and an experienced 'sparky' shouldn't take more than around half an hour.

    The end of your G-Spot with the wire coming from it (Anode of SCR) connects to the end coming from the ignition key, the other end (Cathode) connects to the end going to the starting solenoid.

    Crimp your G-Spot in place before running the sensing wire to a screw or other conductive spot within easy reach of the driver - this must be isolated from the vehicles earth!

    Test your installation by turning the key to "Start" while simultaneously touching the vehicles G-Spot.  Once you're sure it's working, wrap tape around the main unit to conceal it.

    Note:  You must be earthed while doing this so if your keys are plastic coated you may have to slide a finger down onto the barrel of the ignition (usually earthed) or get an uncoated key cut.

    If it doesn't work and you're sure you're earthed, etc, try giving your fingers a lick otherwise a separate relay may need to be fitted due to the small voltage drop across the SCR.
