I attempted to fit my Alpine X801d-u with the 801t5 plug and play kit. Wasted 2 hours. It didn't plug and play at all. The internet lies. What are these wires. I'm holding the alone wiring harness. Is misses a fair few cables. The blue and green oem wiring blocks are completely missed. So is done of the beige. What are the 3 smaller bits. One must be dab. I plugged the main plus in and nothing powered up. I'm quite clued up on car audio add it's my hobbies but I'm stumped. To top it off my airbag light is not on. No idea why.
