[s-cars] Coil solutions

[Mike Fitton]

I'm in exactly the same boat re cracked insulation and visible copper.  
Been that way for at least a year when I replaced the VC gasket and got 
a good look at all the wiring.  It's not pretty, but it has held up well 
and I haven't had any ignition trouble yet.

I looked up and down the 1.8T route and just can't figure out a way to 
make it work for me.  I just don't see it as a real solution to our 
original problem, only a clever way of avoiding paying like $170 for a 
$20 mosfet.  At least for $60 you get a coil and mosfet all in one.

So option #3 is where I think many of us are looking these days.  We 
have the coil choices narrowed down to a few (though if I'm not mistaken 
the only real difference is in the packaging and we can each decide 
which package we prefer), we know which factory plug wires are 
appropriate or some of us have the ability and patience to make our own, 
and all we seem to have remaining is a pair of clean harnesses to go 
from the ECU plugs on the firewall to the five coils' inputs.

If I knew anything about GM anythings, I'd have already done it.  But I 
don't.  I get the firewall plug part and how it might be difficult.  
Audi didn't make a harness for that...and we're trying to make a harness 
for a harness.  Whatever...in my head I'm seeing some nice 
weather-packed molex connectors (or something to that effect).  All I 
need is the GM harness that goes into their coils.  I'll get just a 
harness and pin kit and do the crimping myself if I have to.  Only I 
have no freakin clue where to find such a thing for a GM product.  
Someone fill in the last piece?

-Cheers!
Mike
