This has been brought up in other threads, but I wanted to hear your experiences and ideas on which circuit to use for a power source for relays, other items etc. and the issues or concerns using those circuits.
I have used the Green / Blue wire on the diagnostic plug to power my HyperLites controller (easy to get at etc.); but I found out through Robert that sometimes that is not a good idea. Here is a thread that shows it sometimes doesn't work - 06 R1200GS Battery Warning Light is ON
... and to take JVB's suggestion seriously - "The blue/green wire on the diagnostic plug is fine for a signal voltage for something like a relay, but I wouldn't power anything off of it."
That is something I would have found out the hard way.
Any more suggestions, experiences?
Thanks to all.
