i have an 89 pioneer. just got a new head unit, amp, and a sub and box. nothing crazy just a little 10" in a ported box hooked up to 300w. now heres my scenario. got the wrong wiring harness. and after taking out the stock headunit someone previously cut all the wires to the stock harness and are all kind half *** wrapped together and rolled over with electric tape. would i be better off just wiring the pioneer wires right to the stock ones instead of waiting for the new harness. i figure they're all cut anyway and i could atleast make sure the wires are wrapped together good. the guy i got it from said the radio cut out here and there and i'm guessing this is why. if i did do that what do i do with the extra wires that aren't on the pioneer harness.
mine doesn't have an illumination wire. so what would i do with the stock illumination, dimmer, and antenna trigger wires?
