Just to clarify some things in these instructions....
When you separate the four RCAs, each one will have a bare ground wire and a shielded color wire.
In the diagram I see the the Signal Positives (FR+, FL+, RR+, and RL+) all correspond with a solid color wire. I assume those are the shielded wire from the RCA.
Then I see the signal negatives (FR-, FL-, RR-, RL-) which I assume are the ground wires off each RCA. These are the ones labelled GRAY/BLACK, PURPLE/BLACK etc right? Just want to make sure I put them in the connector right the first time!
I've wired up plenty of stereos and amps in my time, but never made my own harness!
Yes, refer back to this post: Nakamichi Update - '99 LX 470
Since I could not simply de-pin the Metra adapter and slide those terminals into the Toyota connector, I had to get busy cutting and splicing.
I am glad I got that Metra adapter from Crutchfield, because it gave me color coded RCA wiring to go from the Pioneer pre-amp outputs into the factory wriring.
In the next picture you can see how they used a common ground for the Toyota ampifier. The Nakamichi does not. I had to take that common ground apart and give each one a terminal. Not sure if everyone knows, but with RCA wires, it is the outer conductor that is the ground.
The last picture shows how the crimps in the Metra piece were not all that great. I did not have any problems (other than $) with the Toyota repair terminals. If you get your own terminals, make sure you have a good set of crimpers!
