So I got this solderless SG harnesss made by Mojotone and I am having a rough time with it. It doesn't keep my vintage p90 wires in the the terminals, I can't rely on it. I just want convert it, or modify this to a common, regular set up. I am not very familiar with electronics but soldering more so. Does anyone have an idea of what I should do? I'd like to keep these electronics and not spend anymore money on this guitar. Ps: 1-G is Neck hot and ground. 2-G is Bridge hot and ground Thanks, Sam
