Apologies if i'm stating something that has already been said.
Switched 12v can be found in the radio harness. In the white 10 pin plug, pin 3, red wire. I believe, I haven't checked, the radio is fused at 10 amps, there's no need to add an inline fuse, but you can if you desire.
Illumination/Dimmer (+,-) can also be found in the radio harness. In the white 10 pin plug, pin 10; white 6 pin plug, pin 5. Purple (parking lights); Black/White (dimmer).

The reliable place for the tachometer signal is at the camshaft position sensor on pass side of engine, gry 3 pin plg, pin 2. green/white
Once again, sorry if these were answered previously.
