Thanks for the reply!
I appreciate your explanation... we are on the same page here, as the
white/black wire heading to 56a on the bulb, is the same wire you are
speaking of... so it should work fine with the blue high beam indicator.
thanks.
The main reason I asked in the first place was because I saw a posting on
how to do this upgrade, purely at the steering column, using the wires off
the high/low beam dimmer switch to close the relays, and not cutting any
other wires.
I took that as a starting place, and then drew up my own diagram whereby I
also replaced the wiring to the bulbs... and when I looked, there was indeed
a problem with the blue indicator, on my new diagram.
Anyway... problem solved. I will take a stab at this project as soon as we
get another nice warm afternoon here.
