hey guys wifes car is pretty stripped out now so im just wiring inthe rear fogs.
iv noticed i dont have wires at the rear for them(JDM),but there is a harness at the rear called F15(rear wiring harnes combo).

now upfront on the JDM i see i only have Fog lights A41/A51,and no DRL A42/A52.

but i have this plug in the center of the grille area,unidentified on the wiring diagram, its black and has 4 wires into it so (B)4 id say but what is it??


and this spre connector A40(trailer Harness)

 

what wiring diagram are you referring to?
where are you getting these connector numbers? are the molded into the part?

Looking at page 80A-5 in the service manual "configuration diagram" in volume 3, A40 does show in the diagram as being for the trailer harness.

 

no the trailer hanrness is unnder the lh light buddy, i dug around ebooks and found out its a front harness connector for corner sensors etc
