Ok, I have a 93 civic, and it has an h4 bulb. I am doing an OEM HID retrofit, and I want to know how to properly wire it. If you arent familair with HID, the ballast dosent like to be flickered, or, if you switch to high beams, and then back to low, and the ballast is wired off low only, it will restart. This is bad. Not only will it damage the ballast, but also leave you with no light for about 15 seconds.

Anyhow, I want to know how to wire the ballasts, so they turn on with the low beam and high beam, ONLY when the headlight switch is on. Therefore, when the switch is off, as during the day, and I hit the "flash to pass" the ballast wont see any power. I am thinking, Using two relays, the low beam feeds into the high, so when the light switch is on, the high beam will open the high relay, and power will flow from the low. But how do I keep the low beam relay open only when the switch is on?? If its off, only the high will get power when the "flash to pass" is pulled. That is my delimma. Keeping the ballast fed, from the low and high beam, only when the switch is on, but it dosent get power when the switch is off, and the "flash to pass" is activated.

I figured the 12 volt gods could show me something I havent thought of yet.

I was thinking if there would be some way that the high beam relay could only be activated after the low beam relay. So, the high can only activate to send power to the ballast, after the low beam relay has been activated. But I dont know how to do this, since the low beam turns off when the high beam turns on, otherwise I wouldnt have this whole problem. hahaha.  So how do I go about doing that??

Sorry about all those posts. I didnt try to spam. I already know about all that, and my multi switch dosent have a tap in point. I just want to know, how to make 1 relay, turn on, ONLY after the other relay has turned on.

So, relay 1 is on, then it turns off, and relay 2 turns on. Or, relay 2, will only send power if relay 1 has previously been on.

Connect triggers wires of the relay(s) that feeds ballasts directly to headlight switch, electrically before multifunction stalk. Having wiring diagram availble is recommended. If not, you can simply obtain access to rear of headlight switch, and try out the different terminals using a 12V test lamp.  you won't have to worry about it this way.

or

Connect trigger wire via a 4 second delay to ignition curcuit. The delay will turn HID system on after you have started engine, regardless of night or day. So this would serve as a DRL function as well.

I had thought about that, but what about when I want the lights off when the car is running?? I was thinking about also tapping into the ebrake switch, so when its pulled up, it turns off.
