OK, got my full stereo for christmas (headunit, sub, amp, box, satellite radio and all my wiring s***). Everything came in except for my Metra wiring harness. Come to find out it was lost in shipping and I have an appointment tomorrow with a close friend of mine to install all this before I leave to go out of town this week. Is there anyway possible to hard-wire my aftermarket headunit into the stock wiring without the metra aftermarket wiring harness?? Is there a how-to on here anywhere? I tried searching for it, but I never found what I was looking for. if this is possible, how hard is it to do exactly? Please let me know ASAP because I wake up in the morning and will be going to install all this. Thanks.
