I hope you get this soon but I was looking at your site and I am building something similar (I'm using 3 batteries instead of 2) but I saw that you hooked the negative to the switch then connected the other side to the atty and the positive only went to the atty. is this correct or should there be a way that the positive is hooking to the switch also? Please write me back ASAP because I am supposed to get my atty connector in the next couple of days and need to know by then so I can finish my mod!
