brake and turn on leds

Hey great site, I want to wire up my Leds on my bike so that they are both turn signal and brake. I have two rows on both sides of my rear fender with twenty lights on each side, I also have a center brake running light with leds. I know that I need to have two realays on each side but do not know how to wire them. I know relay basics but am stumped. The Leds I have under control, I already have them and the resistors figured out. Yes I know they make a module for this but the kit is fifty bucks and I now that I can do it cheaper with relays and be more reliable.

I think I found it in a old post.

Need to study it and see if it is what I need. Thanks Steve
