High Beams on without momentarily blankin

OK,

You can tell I'm STILL thinking about this one!  My existing Fused/Relayed Upgraded H4 Harness is plugged into the stock oem H4 plug.  Can I pull that plug, take the parking light hot and go to where the low beam h4 harness is?  That way, if I'm thinking this through, the signal to trip the relays will come from the parking lights and use the existing connections to my low beam HID's ???

If so, then I would only need to use my PIAA (Highs) 12v+ and go to the high side of the upgraded H4 harness?  Would they interfere with each other since they're both on the same set of relays/power?  The trigger for the lows would be from the parking light wire and the trigger for the highs would be from the Piaa's?  Hopefully, I'm not back to square one???

Thanks - I'm just looking for a way to keep my existing harness and perhaps avoid duplicating the relay set-up

I'm confused with the Piaa highs 12Volt+ wire your describing.  The part your describing using the park light to trigger the lows on the existing HID harness is cool.  I would use the high beam trigger to operate your Piaa High beams either wired off the factory harness if wattage allows you to without overloading the factory harness, or with another upgraded harness.  Try to keep your systems simple and isolated if possible.

Hmmm.  I thought this was getting too easy - And I was going to begin diggin into it in a few minutes.  The Upgraded harness is connected DIRECTLY to the oem harness in a plug and play fashion,  It provides direct battery power that's fused and through separate relays.  In our idea before my last brainstorm, we were connecting the parking light 12v to a realy to kick 1HID and then do the same on the other side.  I've seen a couple of schematics that have 1 relay used but both HID's fused before and after the relay.  Then we were going to use the 12V Piaa to the UPGRADED High Beam leg.  So, technically, the HID's wold be off of the existing upgraded harness and esentially re-wired.  The Piaa's WOULD use th upgraded harness.

After thinking that through with the relays and wiring - I thought I would try and flip it by using the Upgraded Harness for the HID's as is, but disconnect it from the OEM harness (still receiving the 12V trigger off of the parking lights) and then it WOULD be isolated.

Then, the 12V+ from the piaa's CAN go to the OLD OEM High beam trigger through ONE relay and fuse.  That way, the HID's would come on with the parking lights using the upgraded H4 Harness that's been disconnected from the OEM harness AND the HIGH Beam Piaa's would be controlled from the EXISTING High Beam Switch / Flash To Pass Swithch through the ORIGINAL OEM harness via a relay/fuse.

Am I crazy, or is this the ABSOLUTE easiest way to pull this off.  I think it may be!

Please let me know as soon as you can - my hope is to start within minutes!  Rick

Update:

I took the 12V hot side of the parking lights directly to the input of the upgraded harness' low beam (Disconnected it from the OEM harness completely) and tested one side and it works on OEM switch parking lights AND on Head lights - PERFECT!

Then, I ran the PIAA 12V+ lead to the OEM HIGH Beam harness and the Flash to Pass AND High Beams work perfect and are totally independent of the HID's! I (at this point) have NO additional relays OR fuses since I don't think I really need them, right?

The Upgraded Harness is protected with relays AND fuses and the PIAA's are on minimally and are getting power from the OEM harness and the wattage is identical to Stock Headlamps @ 55 watts/side. Am I ok with this? I have not tried HID #2 yet … still in test mode - but this SEEMS to be PERFECT!

Comments?

Thanks, Rick!

Brock,

OK…

So, here’s how it ended up: My parking lights will now control my HID’s, and my Flash-To-Pass and High Beam are hooked up to my PIAA’s via the column stalk. EXACTLY how I wanted it and FUNCTIONING … at least during my minute or two testing.

I took the 12V+ from the parking lights DIRECTLY to the Low Beam INPUT wire of my upgraded/fused/relayed harness that gets power DIRECTLY from the battery. I disconnected the OEM socket from the Upgraded harness so it is completely independent now. It was initially getting the 12V+ from the OEM socket via the dash mounted headlight switch. I did not use ANY relays or ANY additional fuses since the upgraded harness has both already. Am I correct in assuming this?

Then, I ran the PIAA 12V+ to the original OEM High Beam socket – also without ANY fuse or relay since the current draw should be that of the originals: 55 watts(ish). Am I correct in assuming that this is also OK?

I REALLY don’t want to do anything else with regard to wiring and relays and fuses and soldering and shrink tube/tape stuff if I don’t ABSOLUTELY need to, you know what I mean?

Thanks again for all of your assistance throughout my "little project" and I look forward to your thoughts on the outcome!

Mike,

Thanks.  That sound a bit over my head ... but perhaps manageable.  I was able to solve my final issue of my HID's "pulsing" along with my parking lights.  I used another relay off of SWITCHED hot to break that connection between my parking lights and my low beam grigger for my HID's.  Now, when my car is OFF - my headlights will not work - which I'm fine with.  And, when my alarm "chirps" and "flashes" to confirm arm/disarm - ONLY the parking lights flash as initially installed.

If you read my early threads ... the problem sort of changed mid-way through.  First my issue was that I was losing my High Beam function since I added HID's.  I wanted a way to keep them on WHILE using the FTP or High Beams ON so as not to freak them out with the power surge.  It's an interesting read and I did it for much less $$$ than I was initially thinking about!

Thanks for looking at it and let me know your thoughts after you read through them - if you have the time.
