fast blinkers

[DVFEIT]

I have the Hotbodies undertail installed. I found the flasher relay next to the fuse block. The existing relay has 7 terminals with associated wiring. Is there a relay assy that I can use to replace the existing relay or will I need to pull out a few wire(which wires) from the relay rectangular socket & attach to heavy duty automotive relay. Does anybody have any photo illustrations? I don't have a wiring schematic.
Thanks for any help.
