If I'm reading my book right, that's a high-current circuit.  Your best
bet is to do a relay, or a solenoid.  It would be best if you located it
near or along where the coil wire would normally run, but you don't want
it to get overheated -- if you have to, put it over by the ignition relays
on the left side.  Just be aware that by doing this, you're adding
additional issues into the circuit:

1) relay to fail
2) connectors to corrode
3) additional wire length adding to circuit load

And be absolutely certain that you stick the highest-amperage relay on it
that you can -- I just had a 25-amp rated switch permanently weld itself
into the 'on' position when I thought I was on a 12 amp circuit.

As for the circuit itself, I'd probably run current into the switch, then
out the switch to the input of the relay, then output from the relay to
ground.  You don't want a huge amount of current running through there,
and you most definitely do /not/ want it from the wire supplying the coil.
(You don't want that much amperage running through your switch, nor do you
want to try to match the resistance of the coil to avoid current being
routed away from the coil.)

Then again, I've never designed a circuit for this purpose.  YMMV, as
always.  But whatever you do... /please/ take the time to document it, and
keep copies of the documentation with your title, with your shop book (if
you have one), and in your glove compartment.  You will be glad you did.
