I just installed a sprint RE on my mazda b-series pick up, It has a T2 engine with factory CAS and coils, I have double checked the wiring and everything looks good.

I have engine speed when cranking, I do get a spark when tuning the ignition on but nothing when cranking, I even took out the cas and spun it by hand, It triggers the fuel pump but no spark, I have constant power on the + side of the coils.

Can someone post the CAS wiring, I have tried connecting all four wires and even two wires. I'm a little confused which way is the correct way.

 

Found the issue after 6 hours! The CAS connections utilizes two wires from the ignition wires (gray harness) and two wires from the Home wires (gray/black harness) I'm used to installing microtechs where the CAS wires come in a single harness not two.

Hope this information helps somebody in the future. Please excuse the temporary test wiring but you guys get the picture.

 

yeah, it can get confusing sometimes. just gotta pay attention to the wireing diagrams and read, and read again.

one set of wires is for home, the other set is for main. then transfer that over and boom, its working.
