Hi Jordo,
The two different sensors you have there are most likely used in factory fit for sequential (as long as this word means individual cylinder!) injection and ignition control. The computer needs to know where each cylinder is on each crank rotation, and also needs an identifier signal to know which cylinder is #1 etc.
I wired in my M4 motec using DUMB mode i.e. CAS (trigger signal) only. You need a distributor in this mode. This will only allow batch firing of injectors and overall ignition control - no individual cylinder trimming.
Your ecu will quite possibly be able to utilize a trigger and a reference signal. The trigger signal tells the ecu there is a cylinder ready to fire and the reference signal alerts it (at minimum) to where TDC #1 is on each rotation.
Without knowing the 4G63 I am making an assumption that the CAS supplies trigger signal and the Cam sensor will supply a reference signal, so you will probably benefit from wiring both in...
Cheers,
Jason
