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"
