Haltech ps2k into 20b cas & ignition questions

Postby addicted4life » Wed Feb 28, 2018 1:51 am

Hey guys, having a bit of confusion with all of my web searching. I have a 20b and a ps2k with flying harness and fuse box. everything is wired so far except for my cas. I cant find a diagram for the 4 wires coming off og the cas


Do i use he home or trigger wires? what type of sensor, hall effect or reluctor?
Any links to images or other sites that I have found in the rx7 club forum are unfortunately dead

Also, I havent powered the ecu up yet and adjusted any settings. I wired the primary injectors as 1 2 3 and the secondary as 4 5 6. Now I also set my aem coils up to be front rotor 1 2,mid rotor 3 4 and rear rotor 5 6. Am I able to set that accordingly in the ecu or did I wire the ignition incorrectly :cry:
I am using AEM coils (30-2853)

20B CAS is the same as the 13B unit.

Red - Trigger+
White - Trigger -
Green - Home +
White/Black - Home -

INJ123 goes to Primary 123
INJ456 goes to Secondary 123

IGN123 goes to Lead 123
IGN456 goes to Trial 123
