What i did 1.find the purple wire in the large loom just behind the ECM.
it would be a 10 Ga. purple wire (the only one in their ). in the FSM you see
that c100 connection that is the bulkhead connector going into the car. I
tapped into the wire just behind the ECM.
2. tap into the purple wire (i did not cut mine) run that wire to a relay mounted
just above the battery (swing contact) other end to a inline fuse then to the
battery. connect your normally open moment switch ( I used a flip up covered
toggle switch) this switch would send 12v directly to the starter solenoid and
operate the starter. You could mount the switch near the relay or install it
were you could get to it fairly easy in side your car.

now for the starter enable relay. look at the starter enable relay. pull the relay out and open the cover, then solder a wire across the relay contacts.
replace cover install relay. (this makes the relay always closed).
Someone posted that you should run a wire from ground to the black with
yellow trace on #2 of the starter enable relay. that wire goes to the
Central control module ( CCM ).
Hope this helps

thanks very much I will look at all this when I get home. I can't at the moment picture this in my head I have to see it on the schematic. it's probably just a matter of time before I have some incident like this but so far in the 17 years I've had the car I've only had one instance of no starch and that was because I washed the motor. it was a dumb newbie mistake that I made after having had the car for one day. One thing that I have always done on startup is to fully depress the clutch before turning the key. This ensures that the contacts on the clutch switch are fully engaged before current is passed through them. the only other time that I had a no start was when the battery was needing replacement.
