Running S4/5 CAS... Coil/Ignitor question
I'll soon be converting to turbo on the stock GSL-SE block.
I will run:
-S4 TII ECU
-S4 TII harness
-S5 turbo, manifold
-S5 LIM, UIM
-S4 TB, tps
-S4/5 CAS
My question is of how to wire the 2nd Gen leading and trailing coils and ignitors as to work for the CAS setup instead of the distributor setup?

Wire them up the same way they came out of the FC...
That is the leading coil has two posts, both go to the leading plugs (duh) It doesn't matter which way they go. The trailing coils are marked 1 and 2... Front and Rear rotor respectively.
As far as the low voltage goes, plug them into their spot on the harness that goes to the FC ECU... You did save that harness, didn't you? If not, you better get a wiring diagram, several hundred feet of wire, and a lot of time.
