I used a relay in mine powered by the red/blue and red wire( if I remember correctly). This is a 280z. I then used a diagram from classiczcars to put in relays for the headlights. That diagram reversed the low and high beam wires so wire length would work out better. now that I have done that, my speedhut high beam indicator comes on when I put lowbeams on and goes off when I put highbeams on(reversed). When my headlights are on and key is off, the indicator doesn't light up, so the wiring is keyed on power. i don't know if whats powering the coil(the reds) or what I picked up to power the light is keyed power. If its keyed power powering the relay and light, you may be able to use a 5 position relay to make it work.
