I had a Car Stereo shop install this set-up, as they were best familiar with the wiring processes.
I do know they set it up to have a fuse break prior to clamping onto the brake line to insure if anything went wrong it would shut down at the fuse level and not effect the rest of the vehicle.
I took the DIY of the fog lamp install from SIMOTA1 to this shop.
I ordered the relay from Flashing Brake Light .com and went to their motorcycle site, there is a link from the main page. cost was $29.00 for the relay.
So here we go I am very happy.
If you want more specifics of the install contact this shop called " AudioMaster " @ 512-326-9077....speak with the owner. They did a fantastic job, I truly appreciated the work they did.
The green wire is the brake light....
Good luck
