I just finished installing an Honda S2000 start button in my Pantera. The
car has a carbon fiber dash so the modern start button looks appropriate. I
think they are tasteful if given the circumstances.
As it turns out the Honda S2000 start button is the same size as our
existing hazard button! This makes installation easy. To install one you
will also need an automotive relay ( 40 amp ). Here is the basic steps;
1) Either lower or remove steering column so you can get to the wiring
2) There will be a black 4 into 4 connector which holds the wires from the
ignition switch
3) Run the red wire on the end of that connector to the output side of the
relay
4) Run the input side of the relay to the connector where the pink and red
wire are ( I think 2nd position )
5) Run the ground of the relay to ground
6) Run the switch to the switch side of the relay
7) Remove hazard switch and install start button there
8) relocate hazard switch
Of course this won't remove the start switch entirely because you still need
to turn the switch to the "run" position to turn on the ignition before you
can hit the start button. I also added a rocker switch ( you can see in the
picture ) just to the left of the start button. This is my run switch. The
same process applies to the run switch, you will need a relay for the run
switch as well. The heavy pink wire is your 12 volts in for both the "run"
mode and the "start" mode of your ignition switch.
These modifications will remove the ignition switch entirely and remove all
heavy current loads from the new switches.
