I was asked what the wiring is for the 4G54 CAS. Here is how i figured it out. I used this to wire up to my megasquirt for trigger wheel wasted spark operation. Ideally you'd only use the CYL1 TDC pickup and install a 36-1 wheel on the crank for optimum timing accuracy.
You can see the timing configuration here
A bit of data on the pickup. very common and output a nice clean signal. Unfortunately they wont work with teeth much narrower than stock however.
You can see the plug wiring here.
Colours are different in the images but the wire position is the same (function for function)
