[T3] Ignition switch wiring


Hi all,

As some of you may know, I wired my car from scratch using the wiring
diagram in the Haynes manual, plus some borrowed bits from the 12V Type 34
wiring diagram.

Everything works extremely well and seems to give no problems whatsoever,
except for one thing. The ignition switch that I am using doesn't fit
properly into the steering column. It is not a huge problem, except that one
of the electrical terminals shorts out on some metal under the dash. I have
fixed the problem with insulating tape, but would like to fix it properly.

I do have a proper 68-69 ignition switch, although I haven't tested it to
see if it works. The problem is that it has one less terminal than the late
switch that I am using. The missing terminal is "X", which goes to the X
terminal on my light switch. Its function is to make sure that the lights
only work when the car is running.  When the ignition is off, or when you
crank the starter, the lights don't work. I know this is not a feature of a
'69 car, but I like it and want to keep it.

The question is: Is there any reason that I should not connect the X
terminal on the light switch to the "15" terminal on the '68-'69 ignition
switch? In other words, split the "15" terminal on the ignition switch so
that it is connected both to the "15" wire and the "X" wire. This way, the
lights would stay on if I were to try to start the engine with the lights
switched on, which might run down the battery, but they would still go off
when I turn the ignition off.

If this is a problem, how can I use the '68-'69 ignition switch with my
existing, later, set-up?


Thanks,
