Hi there ... yay me! First post!

Trying to install a factory headunit back into a wee Daihatsu Mira. Sold car so taking my cd mp3 headunit out and reinstalling the factory tape HU.

All wiring looks correct but the HU is not powering on at all.

Have tested Red wire (Ignition Switched power source) and this has power all the way to the unit (spliced wire just before entry to hu to test).
Tested the Yellow wire (Clock memory etc - Constant power source) and there isn't power at all on this wire. I plan to correct this through further investigation.

My question to anyone here is "Do BOTH the constant power wire (yellow) and switched power wire (red) need to be connected for the unit to function? Should there be some sign of life from the HU if only the red wire is connected.
