Halo headlights and turn signal question

This idea is so damn cool, that I have to try it. LOL this is bad ***. LOL

So in order for my simple mind to figure this out, I'm going to break it down by the numbers. And by numbers I mean the numbers on a relay.

So here it goes.

30 - Constant power source from circuit breaker. Could I possibly use the same circuit breaker that I'm powering the headlight relay as well?

87 - HALO Hot wires. Left and right. One relay for left one relay for right. Got it.

85 - ground. Wire both 85 sockets together and then tap into the parking light wire, to use the parking light circuit as ground.

86 - trigger\activation wire. Tap the last relay into the left turn signal and the right relay into the right turn signal.

Does this sound about right.

now consider this
86 - trigger/activation wire tap the left relay with a diode into the left turn signal, and with a diode into the parking light
tap the right relay with a diode into the right turn signal and into the same wire running from the parking light to the left relay, and as long as you dont try to use the Halo as turn signals while the parking lights are on, they should work

i think

get to soldering, i want to see this
