What is the blue 4-pin male connector for on the THAR-FOR3 harness?

0 votes
My car is a 2017 Ford Fusion push-to-start. I have a Fortin EVO-ALL to install with the THAR-FOR3 harness and then plan to hook up a MyCar smartphone controller which has a blue 4-pin female with the same colour wires (red, black, blue, white) as the T harness blue connector. Can I hook up the MyCar controller to the blue connector on the T-harness? Just wondering because the MyCar wiring diagram says to use the HRN-LLRS-01 cable which has the same colour wires.  I will be using my OEM fobs for remote start (lock 3x).  Also, do I need to use the 20 pin white and the 6 pin red connectors? I have no idea where those wires would connect to!

The blue connector on the THAR-FOR3 is prewired for Fortin RF-KITs.  


The MyCar will require to use the cable you said, HRN-LLRS-01.


1 wire from the 20-pin connector and 2 wires from the 6-pin are used to control parking lights if they are needed or wanted.
