I looked at my diagram cross-eyed. S1 from Headlamp Switch feeds the HighBeam
indicator not the Ignition lamp. So the question is whether the fused line
should come off the lamp switch or the ignition switch. The difference being
whether the fog/spot lamps should be operational without regular lights.

I am mounting a pair of lights on the project. I made notes of posts to the
list over the years and thought I would be able to search the archives but 'get
too many hits'. I also thought I had a copy of Dan Master's book but I think I
loaned it to someone (and not returned)
So, here are the notes I have:
Ground Relay to chassis by direct connection
Black Ground from Lamp to chassis.
fused 18g line (Red w/Blue or w/White) from Headlamp Switch to 'hot' terminal
of combination fog/spot switch. Should it be to S1 or S2? S2 appears to be live
only when the headlight switch is 'on'; S1 feeds the ignition warning lamp.
Fog Lamp
??g line (Color?) from Fog side of switch to W1 on 'Fog' relay. (I am thinking
18g)
options: Red w/Blue or Red w/Yellow (I think RY)
14g line (??? w/???) from A1 on Voltage Regulator to C1 on 'Fog' relay.
options: Brown w/Blue (same as Light feed on Voltage Regulator) or ??? (I think
NU)
14g line (Red w/Yellow) from C2 on relay to lamp
Driving Lamp
??g line (Color?) from Spot side of switch to W1 on 'Spot' relay. (again 18g?)
options Red w/Blue or Blue w/Yellow (I think UY)
14g line (Color?) from A1 on Voltage Regulator to C1 on 'Spot' relay
options NU or ??? (I think NU)
14g line (Blue w/Yellow) from C2 on relay to lamp
Questions (other than wire color & gauge)
Where should the relays be mounted? Under dash near switch; on firewall near
regulator; or near the lamp (on inner wing near horns)?
I am leaning toward at the lamp end.
If mounting one fog/one spot - is there a preferred side for either? I am
thinking about dual wiring both sides; so that lamps could be switched out as
needed. Also, that means I can run the lines down the same side and bundle/wrap
the wires going to the other side on the cross-member.
If I do run it on one side - is there any reason I couldn't run one 14g line
(NU) from A1 splitting to both C1 terminals (bullet 'quad' connector)?
Suggestions/thoughts/opinions appreciated.
Also, other than British wiring - are there other sources for the specialty
wire (a source that might be local).
Or, if I can't find the correct tracers... what would be the best choices?
Thanks
