[s-cars] Factory POS alternatives?

[David Forgie]

Dave:  Following the early lead of two AudiWorlder's who are using my 1.8t coil pack wiring diagram as
 a guide, I am also going down the LS2 coil path.  On Wednesday, I bought six D585 Yukon coils (they
 have a heat sink on top) and six compatible connectors. The coils (probably Delphi knock-offs) were
 $17.95 each, the connectors with pins and wires were $60 for the six - total with shipping just under
 $200. Today I bought a set of 7A wires (still need to check whether the length will work or not) for
 about $135. (034 has a set for $115, I saw afterwards). 

I already have the Volvo connectors to mate with the UrS harness so it will be a piece of cake.

After that, it's just wiring.
