Any REAL diagrams generally come from the OEM, them not doing it then good luck, there likely may be none to be had.
Best guess is color ones have died in the last 20 years even in the aftermarket manuals as they cost more money to print, they have gone pretty much black and white too. Color was fine on single or two page diagrams but too expensive to print on the 15-20 page ones you need now. Most english cars now are black and white too.
The complexity of modern diagrams is now so much that those things are going away, you have to pay someone to come up with them and nobody wants to do that. The OEM engineers did it before but they use them for other things now, like redesigning parts to break faster so there are more parts sales, and unitizing separate parts to be part of greater assemblies for the same reason. Not to mention figuring out how to install every single part super easy as long as the major assemblies (engine, trans, etc.) are still out of the car and on assembly stands, while making them almost impossible to get to once the car is assembled. That is an engineering skill of the highest order and demand now. Your electrical issue is one calculated to fit right in there too. The OEMs used to care about how long maintenance took on things, now they have flipped that over after realizing the more difficult every single task is even for their own mechs the more money they can charge for it. Why things like so-called 'minor' tuneups have changed from say $25-$35 in the '70s to go for $800-$1000 now.
Adding the ECMs and all the sensors needed did that, the OEMs assume anybody smart enough to be able to work on them have the skills to read the 'useless info' to use it. The Japanese add to that, they love needless complexity, it is in their DNA.
Until some fanboy comes to the front to make up a diagram like that you may be out of luck.
