I got the blinkers from Procycle. they had relays available so I bought with the blinkers.
Sorry I didnt use a wiring diagram

 

I got my kit from Wheeling Cycle too. You do not need any relays for the brake or tail light. The reason your buddy (or whoever he is) said you need relays is to use for the turn signals to put a load on the stock flasher so it does not flash too fast. I would not go this route. Its extra wiring that is not needed to accomplish the same thing the direct plug and play unit that Cycle Gear sells. I forgot whats its called but it plugs directly into your stock wiring under the seat replacing a stock componet (flasher). Good luck.

 

Just now realized that I said "relay" in my post when I meant to say "resistor". Sorry for any confusion. I wired resistors in line with the blinkers.
