Review on 🔌 Metra 70-7550 Wiring Harness: Perfect Fit for 1990-2005 Nissan & Infiniti Models by Mike Walters

I don't see any reason why they don't have a standard connector on the other end (hey, worst case scenario you can just cut it off!). You will need to unsolder the connectors from the ones that came with your head unit. I was also a bit confused about one of the color codes that didn't quite match the standard plugs. (If I remember correctly it was blue with a solid line, not solid blue. I forgot what it was though.) Also probably not their fault but there is no ground wire which I don't understand. Surely the stock head unit isn't dependent on the chassis mass? They don't actually design this part of the car for accidental grounding, so I had to build something with a bolt and nut that hopefully would hold, but I'm not sure.
