I installed my CA-670 and everything works fine. I tried using a PKF2 with the wires wrapping around the coil ignition but it would not work unless the box was next to the ignition vs just the wires in a coil. I tried something else.

First off, will a PKF1 work?

I tried installing that but I can not get it working.

Install consists of :
TYPE B CONNECTOR
1 - PATS CONNECTOR - IGN - connected to red wire form module
2 - PATS CONNECTOR -Ground - NC
3 - PATS CONNECTOR - TX - connected to WHITE/GREEN from module
4 - PATS CONNECTOR - RX connected to GREY/ORANGE

MODULE
BLACK - CHASSIS
VIOLET - NC
GREEN - TX PATS CONNECTOR
BLUE - RX PATS CONNECTOR
RED - IGN PATS CONNECTOR
BROWN - Is this chassis ground or ACTIVE OUTPUT (NEG) BLUE/BLACK 6 PIN REMOTE START HJARNESS from CA-670

With BROWN from the module on chassis ground, the unit flashes the LED with no programming.
