as you may know, some wiring harnesses come pretty hacked up (mine)
This is for the people that get hacked wiring harness and dont have the pigtails or connectors for the ignitor and opt to use the Q45 for a replacement. I did all the wiring for my car (with help of Heavythrottle and FRsport SR write-ups) and my car starts and runs good so far. So here is how to wire the stock CA18DET wiring harness with no connectors, to the Q45 ignitor with Pigtails
6-Pin PlugCA18 Q45Red/Green ---------> Red/GreenRed/Blue -----------> YellowRed/Yellow ---------> Green/BlackBlack ----------------> BlackRed/White ---------> Yellow/Red
4-Pin PlugCA18 Q45Red/Blue -----------> Black/Pink (could be red?) Red fades? Red/White ---------> Brown/BlackRed/Green ---------> TealRed ------------------> Brown
I have CONFIRMED this to work. Enjoy!!
