Todd,
I found getting wires for the GM coils very easy. Simply order a set of
MSD custom wires then call MSD for the fittings.(got mine from Summit)
They will send them free in a few days. Here is the original message
from Al....
"Looks basically the same idea as the MSD 8.5mm wires. Best price I
found on the MSD wires was at www.sdpc2000.com .
"Since the only sets that MSD makes with the LS1 coils end sockets are
factory made for specific engines, I talked directly to the MSD tech rep
and he offered to send the LS1 ends at no charge, so I could put them on
a "universal" set from a retailer. If you are going this route, call
MSD at 915-855-7123 and them you need the LS1 coil ends for your
wires.-Al Gietzen"

Hi Ernest;
> Todd,
> What kind of plug wires are you running there?
They are a custom made plug as the GM 'vette coils don't fit a
standard
plug
wire. I seem to remember the parts guy saying that all the plug wires
are
suppression these days, however there is no marking on the wires to
confirm
this.
Anybody who is yet to order the EC2 should know this when
deciding
whether
to have it set up for Mazda coils or GM coils. When I made my choice I
assumed it would be a no-brainer. Knowing that the Mazda coils are
expensive
and assuming they may be hard to find, I figured that the GM coils
would
be
a cheap off-the-shelf product, available from any number of
aftermarket
parts stores. They are anything but. This is not to say that they
won't
work
well, but just a heads up, that they are not as easy & cheap to use as
might
be expected.

A quick inspection of the inductive pick-ups on both instruments
revealed
that the timing light has far more wraps of a much finer wire than on
the
tach.

Good idea, but as pointed out above, the standard plug wires won't fit
on
the GM coils :-(. Now with that said, I must confess that I haven't
even
tried a standard plug wire. When I bought the coils and asked for
wires, I
was informed that they wouldn't have anything to fit them, but they
were
able to have some made up and shipped up next day at no extra cost.
This is the unfortunate thing about having the airplane at the
airport.
It's not as easy to quickly try new things, when good suggestions come
in.
