Do I actually have to remove the resistors or can I leave them and still do it? The back I can probably remove if needed but the fronts MAY need removal of the headlights because I don't remember where I put them ans would like to avoid that.
Ps. Whose got the best price on it and for the cable needed?

 

The purpose for me was to be rid of the resistors, but I believe leaving them should not be an issue if you can't remove them now. Other than them getting hot and possibly melting a wire against it.
