Further installation notes
Upon installing Touch n Go into some vehicles, certain obstacles could be in place that will complicate
installation. From the late 1980’s to current day, vehicles have become increasingly more complicated.
They implement everything from locking columns to security systems that require coded keys. The
internet provides pretty thorough information on wires, their colors, their function and where they
might be found. This information is usually available and free from third party manufacturer web sites,
such as alarm and remote start manufactures for example. Here are some suggestions for overcoming
these obstacles, and what those obstacles might be.
Newer vehicles
:
More than 4 wires exist at the ignition switch
: Often times all of the wires still have the same basic
functions as an older ignition switch, and can just be grouped together based on desired operation.
The vehicle manufacturer may have done this for ease of assembly.
Locking steering column:
Locking steering columns are managed in two ways: Mechanically, usually
with a spring loaded pin that locks the wheel when the keyed ignition is in off, and electronically with a
motor. You could simply leave the key in the factory ignition, and turn it to the unlock position or
disarm the locking mechanisms. You may even choose to cut the head of the key off so it is less
conspicuous, leaving only the actual shaft part of the key.
Depending on your level of mechanical inclination, you can disarm the mechanical column lock by
removing the pin / locking mechanism. Or you can install a column with no key tumbler in it.
If the car uses an electric motor to lock, it is possible to disarm it also. Check the two wires going to
the motor that activate it. It will use a positive wire and a ground wire, it is possible to independently
hook the wires to ground and a keyed power source, so the column unlocks after the accessory or
ignition power has been turned on. You must observe and maintain the correct polarity that the
vehicles security system uses to activate the motor. It must also be disconnected from whatever
device may be controlling it.
If you are not comfortable doing this, check with a qualified body shop or alarm installation shop as they
need to access these components regularly and may be able to help.
Chip in key:
If you have a chip in the key, it may be visible where the exposed metal part of the key is,
