Honda crv and InvisiBrake

[oscardem]

I just got a 1999 honda crv for a toad, got a roadmaster stow master 5000 off craigslist, then went to camping world and ordered and had them install roadmaster base plate, wiring for lights, an InvisiBrake system and a fusemaster for the radio fuse. It all tows great, BUT ...... I have noticed that when the brakes are applied the turn signal on the honda is overridden by the brake lights when the InvisiBrake is activated. Just brakes...fine, just turn signal...fine, 15seconds after brakes are applied (invisibrake deactivates) and turn signals work again. Is there a second fuse that I need to pull?
