DRLs on with Parking Lights. It works. (Pics)

[Mango]

PhilD, Have a little faith. I aced physics in college . Only way to measure current is to have the voltmeter make the connection. When the voltmeter made contact, the DRLs turned on and the current measured was 125 mA. Took the probes off and the DRLs turned off. No other connection was present in parallel. Promise.

Hey NSXTC,

Thanks for the tip... When my wife dropped me off at the dealership this morning to pick up my new H2 I came with screwdriver and about 4" of 18AWG in hand. I planneds to do the mod at the office in the afternoon but when teh putz salesguy did not have the paperwork ready I found myself with some spare time...
Anyway took all about 3 minutes... Thanks again

OC, Why did you do that at the dealer?

Now they are going to offer it as a 99.99 dealer option that every poor newbie is going to buy

NSXTC,

I picked up my Black loaded H2 last week, and discovered that in fact the lower lights were not fog lights, that they were DRL's.

Thanks for your information.
Operation done.

I would like to get different bulbs for the DRL's, or replace them for fog lights.

Thanks,

The diagram and picture was very helpful. It allowed a nonmechanic less than 5 min.

Just to let you guys know, hooked up the DRL Diode to make the DRL's come on with all the lights and the park lights and just FYI the end of the Diode with the SILVER STRIP goes toward the PARK LIGHT RELAY!! And it works great.... Thanks for the info just thought that I would pass some along myself....BADRAP

just did mine , really easy

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> so I'm not sure why you are getting the 125mA reading, as the DRL's draw more than that, unless GM have found a way to defy Ohms Law.

Phil...

Ohm's Law still applies, even for GM, as well as other rules for parallel circuits.

After the 10A fuse the DRL circuit becomes a parallel circuit with one circuit through the relay contacts through the bulb filaments to G100 ground. The other circuit goes through the relay coil to ground through the DRL control of the BCM or through the added diode to the Park Light control of the BCM, so actually the diode only carries 125mA of the total load.

The BCM could not handle the 54W load of the filaments, the reason for the relays, and the added diode becomes a one way street for the DRL relay coil to seek an additional ground when the park light circuit has continuity.

I'm gonna try the diode thing! Thanx 4 da info.

Looks Like The Last Post on this was in December.
Just wondering if anyone has come up with any problems since doing this?

Did it about a month ago. Simple, easy and quick. Works like a charm.

Not for me over the last 5 months since I did it but I think Alec or one of the other CO. guys had a problem that the dealer attributed to the relay jump.

I have had this mod done for about a year now with absolutely no problems!
