Yeah so I'm using 4 relays instead of 2 disregarding the fan. I wasn't sure one relay would be enough for everything. Plus I thought separating the coils/injectors/sensors may eliminate some noise. Im happy to reduce the number of relays to 3, as I still have an AC relay I want to add
Yup, the AC will go through the thermostat, to the input on the MS. The MS will then control the output to the AC compressor itself. It's so I can have it switch off under wot and certain other conditions.

Yes, you can use a cam sensor from a later model windsor (I've got one in mine just to block the dissy hole and drive the oil pump).
And yes, the injector wiring is definitely different if you're running sequential fueling.
In batch fire, there are two injector channels, so you would wire up 4 injectors per channel.
With sequential, you will run 8 separate injector wires - one to each injector.
Going back to this.
If you had 4 injector channels instead of 2, and had dual widebands, would you wire them up as a bank, or opposing.
Ie, Channel 1 = Cylinder 1,2, Channel 2= 3,4 Channel 3=5,6 etc,
As this would allow the ecu to adjust that banks afr only, without changing the other banks afrs.
Or would you do it in opposing firing order pairs, ie Channel 1 = 1,6 - Channel 2 = 3,5 - Channel 3 = 7,4 etc.
With dual widebands, it seems the ecu would not be able to correctly adjust afrs per bank with this method.
I guess what I'm asking is does fuel injected into a cylinder when it is not on the firing order have any affect on AFR's of that cylinder?
