This mod will allow the low beams to stay on when the high beams are engaged, similar in function to the aftermarket kits. Color scheme references 2003+ models.

Thanks a lot Scott - I think I am going to have to set my burban up like that! Could always use the extra light.

If you really want to stand out, check the other post about firing your DRL's with the low beams, while on high.

Does anyone know of anything similar like this to work on a 96 Tahoe sport?

Absolutely, just follow the same logic and by associating the same steps it's pretty straight forward.

Long Story short: I tried the 4way mod last weekend and just ran into problems after problems. The big hint that I knew that I would be in troble was that my wire colors were different than what was in the document...

Long Story long:
I purchased an HID upgrade for my Z71 and wanted to also do the 4way mod while I had the brush guard and grill off/etc. I had heard it was not good for HID to be turned ON and OFF frequently, so I figured the 4way mod would help my lights and not to mention the extra lighting would be a nice plus...

Well after getting everything wired and tested I kept blowing fuses and I could never seem to switch on the low beams. I later spent time and did a schematic drawing (being an engineer by trade) and pulled out my trusty Fluke meter and started testing the supply and switching voltage on the head lights. I finally resolved my fuse issue and then went on to testing the diagram futher...

I then saw something quite odd...when ever my low beams would turn off as I switched to High Beams, the voltage at the low beam bulbs were aprox 12v to ground on one wire and aprox 12v on the other (without the bulb in the socket).
Not being a car expert, I was suprised to see the "off" go to high - I would have thought that it would be open or brought to ground. But when I turned the lights physically off they would both be at 0v to ground.

SO, I reworked the diagram and rewired the relay to provide a ground when the relay tripped, still no lights - Rats!.

After about 2 hours of this I said, "Oh well, I will check with the local experts here" and try again some other time...

I went ahead and installed the HID ugprade... I love it, it worked great. The most difficult thing was finding mounting places for the HID hardware.

Here is the kicker... But oddly enough, when I switched on my Highbeams the HID lights stayed on already.. Doh! All that work for something that was already provided.

****So, in short, if you are planning to do an HID upgrade AND the 4Way mod, install the HIDs first and see if they will already stay on...

I am still puzzled about the voltage floating to high on when switching to high beams.. dry.gif

Hi CCoder,

I appreciate the feedback. Yes, this mod was strictly intended for the stock lighting system.

I'm not sure what the requirements are of the HID system and/or the schematic, but I have no doubt that these types of issues could pop up.

I'm glad you eventually found that the HID's have this feature built in. Perhaps that have been part of the problem?

It couldn't have been the HID ugprade causing the problems with the 4 way mod, I did the 4way mod before installing the HID upgrade. I was doing it with stock lights to make sure that I had it working first...

The wire colors for my low beams and high beams did not match the document. I have a 2002 Z71 Suburban (made in Mexico) and thought it was odd the colors did not match..

Oh - I did not know you were talking about an earlier vehicle. I should probably revise that to indicate the coloring scheme is based on the 2003+ models.

That said, you can easily interchange the color references for the high and low beams by checking the wiring going into each socket and verifying which is the positive for each.

Thanks for bringing this up. I will edit this. If you can tell me the actual colors, I will include this as well.

Thanks.

2002 colors

Low beam Yellow and Orange

High beam Purple and Orange

I assume Orange is negative in this case but am not sure.

I would guess that too - but check it first. I don't have a schematic.

No luck though wired as directed. Also tried just orange. Relay works because when when I switch back to low beams the fuse pops.

Know where I can get the schematics for the 02 suburbans--cheap?

I had the same problems with my '02.

I can't remember the details, but there was some odd behavior with both wires going Positive (with respect to ground) when switching between high and low beams. I also kept blowing fuses.

I need to get a 4 way mod figured out for my '02. I just received my Helm service manuals on my '02 - I am blown away with the detail provided, well worth the $140.

On '02's:

Orange = +12v to headlights
Yellow = ground w/ low beams
Purple = ground w/ high beams

Headlamps are postive switched (powered applied when the switched is turned on).
Low and high beams are negative switched with the dimmer switch.

I'm not understanding the problem guys. The schematic I came up with for the 03's+ should be exactly the same as the aftermarket versions like Painless, etc.

Ccoder, can you do me a favor and diagram what you had to do? I'd like to get this documented for the others.

Thx man!

Hey Scott,

I'll try and map out the wiring. There could just be something "odd" with my '02.

I was never able to get the 4 way mod to work and ran out of fuses to work with.
I was trying to probe with my Fluke DMM to check voltages levels with respect to ground and finally had to call it quits for the day.

I'll see if I can poke and prod on it this weekend.
