Sort of related to "Mustang Down".

Chris, as you mentioned, replacing the resistance wire on an early Mustang (and other early model cars) is easy, as the ignition switch is mounted in the dash.

My question concerns doing the same electronic conversion in later model cars with the ignition switch in the steering column.

Rather than trying to replace the resistor wire in the steering column (pain in the neck), could you run the resistor wire to a relay and then get your 12 volt feed for the coil from the battery or another constant 12 volt source??

This sounded fine in my head (amongst all the other voices), for two reasons. 1, you don't have to climb inside your steering column to replace wire and 2, if you got your 12 volt feed directly from the battery (via the relay), there'd be virtually no chance of voltage drop.

:think:

You have got it right Bonne Chris.
In a later model car i would simply pick up ignition source straight from the fuse box and run it through a relay to make sure you have constant 12 volt.
If you want serious performance and reliability i would run an MSD or similar amplifier  to give you multiple and stronger spark. They get power supply straight from the battery and only need a mere 3 volts from the ignition switch to trigger the whole system.
They are compatible with any type of ignition even points.
Starting price is around $300 and takes about 2 hours to fit and you will never have to touch your ignition again.

They even work on 6 cylinder Mustangs  :lol:

What'd you mean by that?? :rol: :rol:

The BIG 6 has been going strong till all this new technology bs came out haha. And it's not by choice as the good ol' police think it's safer to drive a 6 cylinder car with no air bags or safety features over a V8 with air bags and such things as disc brakes...

Gotta love there way of thinking :zip:

The police didn't think of it, they just get stuck with the result.

The other thing is, any modern 4 cylinder car will suck the headlights out of a HJ Holden with a 253, but a P plater can't drive the HJ.
