You probably need a resistor in there somewhere to make the load on the circuit equal to what it is without the additional lights. The manufacturer should be able to help with that.Im convinced theres a direct link between the cruise not working and the sabretooth lights.
Its a fact that when theyre unplugged at the saddlebag connections the cruise control becomes fully operative.
And when the sabretooths are plugged in the cruise wont work.
Sad...cos itd be nice to have both...at the same time.
