ok .. all the wireing is finshed , everything works but the lamp monater is saying that the frount lights are blown, im going to take the wire from the swtich thats not hooked up on the left side and run it to the right side and put it into the input so the loop is complet , im hopeing this fixes the small problem, as i dont like it showing the lights are gone ... should be done with in the next two to three hours then ill post pics

Oh right, I forgot about that...Bonnevilles have that annoying lamp monitor. There is a module you can buy to fix that. But let'* see how your method works first, that may fix it too!

LeSabre. that avatar all but made me juump back when I entered the thread.

I want this mod but not the headaches. Not an electronic wiz. But wouldn't it be easier to relay the highbeam power to the low beam, and put the diode between the OEM power wire and the low beam. So it doesnt back up the harness? Just asking, don't know if its a dumb question.

there is a doide in the mix ill make a digram of mine with all the parts ... i dont know if u could just go from one to the other , my gut says no becuse the lows would not have the power they needed therefor diming the lights to the point of them being pointless , as of now the doide just turns on the relay inturn its just anther swtich ... if u can run a radio and u dont mind chaseing 3 wires from the lights to where u can tap into them you can do this mod i did mine in the parking lot of our bcm ... took about two hours because i took my sweet time ... well im about to go rap her up and take pics

ok everything is done ... my idea didnt work ... i do have a different idean ... the monater dosent bother me but let me know what u think ... leave the normal wireing lows to lows highs to high have the relay piggybacked on the stock wire and use the deiod for the from the highs to the input of said realy then do the piggy back from the output to stock wire ... ill leave as is for the moment but feed back would be great ... ill post piics when i get back to the room, and ill do a small wireing digram of what i did and also of my idea

ok drawing is not my strong point i will try to put it in words so some one else might be able to draw it ... ill wire it up and see if it works if it dosen't turn off the worning lights ill just cut the wires out and go back to the last version i'll do it tonight after i get off work it should be posted by midnight my time im hoping that the lamp monater goes away.

ok, heres my plan

leave the stock wireing as is. wire up a realy as posted in thread. take diode tie into the high beam wire and take the other end and put in the input tie the out put into the stock lows. this should leave the stock set up on the lows and when the highs are on it would put power to the lows as well the highs ... ... any thoughs?


god my wires are going to look like a hack job, but when done hopes are they work with the monater and light up with the highs to

Good ideas here. I think I've found ultimately what causes the lamp monitor to freak out.

The problem is, the current that is allowed to pass through the relay from the stock wiring (input for low beams) is very small when compared to what normally passes through. The lamp monitor reads this reduced voltage and registers a failed bulb even though there may in fact not be one.

I think I understand what you're saying, and I'll try to draw it up myself in MSPaint, sounds like it might work. Lemme draw it up right quick, do some thinking and figure this out.

Man, I'm glad my car doesn't have a lamp monitor, lol.

Okay, here'* my extremely crappy attempt to draw your idea. I think it should work, good plan! This will also boost the lows while the highs are on giving you extra light. You will retain factory brightness levels while on standard low beam.

Let me try to decode this crap for you.

Everything in black is factory wiring, everything in red is added on wiring or the relay.

HL = low beam headlight, pos and neg terminal labeled (+,-)
HB = high beam headlight, pos and neg terminal lableled (+,-)
R = relay
D = diode
i = input signal for the relay
o = output from the relay

I didn't show the power and ground connections for the relay, but that'* a given. Also this is just for one side, another wire from the output terminal of the relay should go to the positive lead on the other low beam headlamp.

Let us know how it turns out, and if I missed anything!
