Hey, I work with body parts, not electrical stuff (my brother-in-law laughs at me everytime we're building/working on something...can't even get the tool names right...). Yes, it's a diode. It's from radioshack...I know the part number is listed somewhere here on the site, might actually be in this thread... If you can't find it, let me know...actually, let the members know, they'll direct you.... It only cost about $1.

And, yes, you're right. During the day, the DRL's are on only. At night, when the headlights turn on, the drl's stay on. They pretty much run night/day... I don't have the option of turning on the DRL's on without the headlights though, which is what the other connection will accomplish.

almost 2 years later...I finally did it.

Good for you Albie. And we both "dumbed" out on the no lights, huh?

HEHEH yes we did.

Great Thread!!! used the diode and works like a charm!

old thread so a bump for those who would be interested in the same

Hello Everyone

If I like to have the DRL lights on only at high beam, how do I do the wiring then??

I like the look of the DRLs on with the headlights, but not the park lights. Why can't you jumper the headlight relay instead of the park light relay?

You can jumper it to any relay you like, even the horn relay if you want . Just use a diode instead of only a wire, that way you don't get any reverse action of the DRLs also turning on the "whatever relay".

I think I might go pick me up a diode baby!

I will do this tomorrow! I think I will be doing the low beam and DRL combo!

Hello everyone

I tried to get the DRL:s on at high beam only like this (only the blue line) but that was wrong. Anyone knows how to do it?

OEM DRLs are for sissies.

GOT PIAA?

This should work. I currently have my drl's on with headlights-low. You could easily switch that to Highbeams....with the blue line. I guess I may try using a line to the highbeams along with the low beams, so they don't shut off with high.... I haven't tried the blue line yet, so let me know if it doesn't work...

Hello dochummer

Thanks, I will try tonight. I will let you know.

Hello dochummer

Thanks, it works with the wiring like the blue line.

Tomas

Glad to know it worked!

DOCHUMMER,

I want to have my DRLs on during the day and at night with my low beams. I don't want the parking lights on during the day only at night.

SHOULD I:

Jumper the drl and low beam relays as shown above in yellow only? No other connections?

Also which way does the stripe on the diode face towards the drl relay or the low beam realy?

THANKS...this is a great mod!!!

Check your pm...

By doing this with a wire rather than diode, does the low beam remains on with DRL also at all times in "auto" light setting during day and night?

Yes. The wire will allow the current to flow both ways so the drls will also activate the headlights during the day. The diode is pretty cheap...I think less than a buck for two.

I think the side with the mark faces towards the DRL relay. I can't see the mark anymore d.t. the way I've set it up.

Here's the relay: RadioShack (part No. 276-1102 "1N4003 Micromini Silicon Diode")

Dochummer, Sir Thank you.

Anyone have problem with DIC saying "turn signal on" after doing this mod? Mine comes on when I did this mod. I have the DRL come on with low headlights.

nope. Checked the jumper settings?

I decided to do this to my truck the other night and, while I had the soldering iron out, I made a total of three jumper wires with diodes. I obviously only need one of these so the first two people to PM me with their address will each get one. The diodes are soldered to black wire on the 'feed' side (the side that goes to the parking light, low or high-beam relay) and red on the side that goes to the DRL relay. They're heat-shrinked and long enough to allow you to attach to any of the three aforementioned 'feed' relays...just cut to size and be on your way.

I think I am going to have my DRLs wired to a switch so I can trun them on at any time.

For those interested, I have seen the DRL bulbs available in yellow so they can be used as fog lamps.

Alright, I have just read the last 5 pages of updates and I am more confussed than when I started. If someone can summerize what I need to do I would really appreciate it. I have an 06 that I just want to add the DRL to the auto function for use with the Headlights. During the day I would like them to opperate as they do normally without any additional lights or markers on. Lastly can anyone tell me what they would reccomend if I want to upgrade to a brighter DRL and Headlamp without the cost of the HID's. What DRL bulb would compliment the Silverstar Headlamps?

CAUTION CAUTION CAUTION, I tried the jumber today on a 06 H2 exactley as outlined with the jumper and the diode. Worked for about 30 seconds and then it started spitting and sputtering and stopped running. Tried restarting it several times had to have it towed into Hummer they said that it has fried the ECM. This vehicle only has 380 miles on it. They will not warranty it, I ll know tommorrow what it is going to cost. Has anyone had anything like this happen. HELP!!!

Bummer about the fried electro-BBQ. Methinks you did not do it correctly, unless AMGen redid the box. Even then, the schematic should have shown you the correct slots.

Does anyone know if the Fuse box did indeed change from 05 to 06?

No idea on the fuse box, sorry to hear about that though. I just tried this mod, and it worked successfully. The one wire keeps the DRL's on at all times, even with High beams. Now, I just have to get some serious DRL bulbs and get rid of the sissy stock ones!

I did this mod in Jan 03 and eventually needed a new fuse panel.

Man, have you found anything out? Did you mistakenly place the wire incorrectly? I was going to do this (even made up the diode) but not until I find out what happened.

Keep us updated please.

PS. My bodyshop does alot of business with the local Hummer dealership. I don't know if it'll help but get your price and I'll see it I can get it for your cheaper. Right off the bat my shop gets 25% off list, if I have a problem child, they usually help us.

PM me if I can help.

Mark if you can get me a price on the ECM I would appreciate it. I told the dealership that I will tell them by Friday what I am going to do. I still can not believe there isn't some way they can warranty that part. If you can PM me as soon as possible I would be very appreciative

PM sent.

Not sure what you were quoted. But this may be cheaper?

Not sure if this helps but here it is.

The PCM for an '06 at my cost is 318.00

If I can help you, let me know.... it lists for 585.00

Mark,
Thank you for the price on the ECM, can you find out how many hours the book calls for the replacement of the modual I am trying to get a total price. This way I will be much better prepared when I talk to the dealer on Thursday.

Thanks Again!!!

Ok, I haven't actually replaced the pcm in an H2 before...but it's not that hard is it? I've replaced pcm's on other vehicles and it was a matter of disconnecting cables, and swapping it out....

I'll check tomorrow but I honestly can't see it taking very long. Most ecm's only take a few minutes to replace. Sometimes you may have to remove some bracketry/battery/brace to get to it but I couldn't fathom it costing more than an hours labor.

However, I will check tomorrow.

Mark

I was told that the ECM on a 06 H2 is up under the dash behind the instument panel and that it is quite involved to get to it. I was told that the whole dash practically has to come off to get to it. I hope someone can tell me exactly where it is and how many hours the book calls for to replace it.
