Nakamichi Update - '99 LX 470

[mr470]

Are you talking about the connection at the head unit?

Yes.

As far as the bypass I connected the speaker in/out. 4 pairs. Then on the orange connector I spliced the gray/gray
White/white.

Post pictures, that will be worth thousands of words…

Thank you, @PabloCruise, and everyone, for the wealth of information this thread has given. The Steppecruiser guide on page 6 was helpful, and I ordered the crimper he recommended. I successfully installed my Apple CarPlay unit in my new-to-me 2000 LX470. I was initially a bit nervous, thinking about what I got into with a Nakamichi unit. The hardest part was probably making the harnesses, as someone with no experience with wiring/electrical. The crimper works, but it is a real pain as you have to keep crimping to reduce the width of the crimp to fit into the 22-pin harness. But can't complain for a $33 crimper. I had to order some connectors and a heat gun to connect the ground of the RCA to a bit of wire I cut off the Metra harness. That was the most complex part of making the harness, and if I ever have to make it again, I will try to make it a little better and the same length. I did lose my power antenna function, but hey, who listens to the radio anymore?

This is awesome. I have a couple "under the hood" items to address and then I will be posting an update here on the progress.
