Alright, so I ordered a keyless entry/alarm/power door lock system and I need some help installing it. I'm wondering if the harness from the system gets spliced into the existing wiring, and also where the best location is for the box. I also got 3 relays with the system, and I'm not sure exactly what they're supposed to hook up to yet. If anyone could help me, I'd greatly appreciate it.

 

No-one knows?
