hi new guy with aftermarket radio question, i know you r probaly tired of this question but i been reading the posts and am not sure. I got a kicker comp vr12 from a friend with amp and a box for a 100 since he was tight up for money. I definitely dont have BA stuff and honestly dont care about the steering wheel controls. So am i reading right that i can use regular harness but just gotta run my own power source and probaly my own ground or is it required no matter what for the integration kit. I mean if i gotta make own power source ill just run it to the fuse box for something that only has power when key is on and its not hard to find a ground.
