Don't laugh at my drawing.
Now why would I do a damn-fool thing like that? :shrug:
From your drawing I get this:
30: To source of ignition-on line voltage.
85: Relay trigger, to ground.
86: To vehicle side of (cut) original front turn signal feed wire.
87: Not used.
87a: To front turn signal filament via lamp side of (cut) original front turn signal feed wire.
So with no power on the vehicle side of the turn signal feed wire, the NC contact is closed and we have steady power feeding to the front turn signal filament, which therefore burns steadily. So far, so good.
When we signal for a turn, we have pulsing power (thanks to the T/S flasher) on the vehicle side of the front turn signal feed wire. Each time there's a pulse of power, the NC contact of the relay opens and interrupts feed to the front turn signal filament, which therefore flashes.
BUT!
We have an inversion effect caused by the NC relay: when the vehicle's turn signal feed wire is live, the relay is open and the turn signal filament is dead. When the vehicle's turn signal feed wire is dead, the relay is closed and the turn signal filament is live. So the front and rear turn signals will not flash in phase, they'll flash in opposite-phase (front turn on with rear turn off, rear turn on with front turn off). Tell me why I'm wrong. If I'm right, that violates the applicable regulations; the only exception to the requirement that all turn signals flash in phase is that the front side marker light (on '68-up cars so equipped) may flash in opposite-phase.
