Hey you guys, with all this chatter you could have built your own.  This was
a good job to give my wife.  I taught her to solder and she had them done an
hour later on one of those rare evenings she came to help.  I poured in a
little resin to fill the space, and later topped it off with some RTV to
soften the transition.  Cost: $0.

I have attached a comparison photo my coil connector p/n 1258-2190 wiring
harness which fits LS1 coil p/n 1255-8948.  The AC Delco part for just 1
plug and a foot length of wiring is PT368 or GM number 12102741.

It appears the two connectors that Mark and I are using are considerably
different.  The most obvious difference is the pins on my connector (p/n
1258-2190 (or 12102741 single plug) are separated by a hollow space equal to
the width of the pin channel itself.  There is no external key.  The key is
a bit of horizontal plastic in the hollow space between the two right most
pins. The pins of the connector Mark showed show no such separation which
indicates either his pins are  much wider or his plug is narrower.

So it looks to me that the coils/connectors that Mark is using and the
combination I am using are not compatible.  So order wisely {:>)

FWIW
