First, I attached the wiring schematic for the entire exterior lighting system for your review. I had to cut the pics in half to make them readable; however, I did overlap them so you can follow from one to the next.
If you look at pic 1, I highlighted the flasher and its location. pics 2, 3, and 4 are the remainder of the schematic.
If you look at pic 5, it shows the location of the auxiliary relay box #1. The last pic indicates the flasher's location.
Here is a link you may find helpful when testing:
I hope this helps. Let me know if you have other questions.
See pics below.
