Removing Rear Turn Signals?

[FreyGrimrod]

I tried searching but my forum fu is low apparently. I replaced the rear plastic bracket on my 2001 GZ250 but can't for the life of me figure out how to dismantle the turn signals to snake the wires through the new plastic bracket that holds them to the bike? Someone here must have done this had the light apart in a buncha pieces looks like there might be a metal tab that if forced with pliers? Anyone?

Thank you for your time and help!
