Just basic wiring help!

Hello!
I'm using an s6 ecu and wanted to run a wasted spark ignition system as it'll keep things simpler. Can I do this by supplying a 12 volt feed and use coil signals for cylinders 1 and 2 to activate the coil?
Second question, are the two pin wheel speed sensors called vr sensors? And would I use a bipolar input and earth it through the ecu and assign the pin for wheel speed?
Thanks in advance
Phil

All correct.

You can assign a single ignition output to multiple cylinders for wasted spark. S6 will need an amplifier to drive non amplified coils.

Ah brilliant! Thanks for your reply. Are you familiar with the vw 4 pin wasted spark coil packs? As far as I know they have inbuilt amplifiers unlike the 3 pin zetec coils. Can you confirm this? I don't want to blow it all to bits! Ha ha

post a picture of the coil pack, there will be many

If it has four pin connector and if it is eg. VAG #032905106B or -E or Bosch 0986221048 then it indeed has internal amps.

Pin 1 = signal 1 in, pin 2 = +12V, pin 3 = signal 2 in, and pin 4 = engine gnd to cylinder head or block.

I have used these dwell times: 8,0V - 5,0msec, 10,0V = 4,0msec, 14,0V = 2,9msec, and 16,0V = 2,5msec. Been working fine for NA and mild boosted engines.
