I removed my stereo on my TR, and have my new Alpine head unit. I have the wiring harness from the alpine headunit which i need to attach to my circuit city wiring harness. Now, I really have no idea what the f*ck im doing from here, and its starting to get me a little frustrated. For example, my black (ground wire) has this C-shape thing on the end, what do i do with that. Then my P.ant., illm., remo, in int, coming from the alpine wires all have these caps with plastic things on the end, what do i do with those. If soldering is involved, can i use standard wire sodder? Someone tell me what to do, PLEASE! Do i have to cut the ends off of the P.ant., illm., remo, in int? I really need help..
