Bruce,
The solid purple wires are always hot. The glovebox light is an example of a
wire you can tap into in order to get power all the time. You wouldnt harm
anything if you followed the wiring harness to your fuse block but there should
be other underdash wires that would be closer. You can always reference a
wiring schematic for your car also to find out other sources if you prefer. I
dont have the link handy but Dan Master's web site has downloads for different
years for free. If you havent purchased his electrical manual then put it on
your Christmas list.

Subject: [TR] Stereo head unit connections
Hello Listers,
I'm ready to connect a new stereo head unit on my '74 TR6 and (being somewhat
of an electronics simpleton) have a question: on the connection harness
supplied with the Pioneer head unit, there is a yellow wire tagged "to
battery." This is an "always on" connection to preserve radio pre-sets and
clock settings. The installation instructions for the head unit say NOT to
run the yellow wire through the firewall into the engine compartment. I
assume they want the connection made on the cockpit side of the firewall.
What is the safest way to make this connection i.e. what wire should I connect
this yellow "always on" lead to? The other leads are: red - to ignition
"Aux/Accessory" contact, black - ground, and blue - to amp remote turn on. As
always, thank you all for sharing your incredible body on knowledge/experience
with the list.
