QCDriver Posted February 17, 2007 Share Posted February 17, 2007 My '01 CH has DRL. I'm going to install a HID conversion but need to shut off DRL's. My question is, can I remove the DRL relay in the dash, will this disable them???Thanks,Doug Quote Link to comment Share on other sites More sharing options...
ThaddeusW Posted February 18, 2007 Share Posted February 18, 2007 So your replacing the regular halogen bulbs with a HID kit? Way cool! If I had a truck with the sealed beam round or rectangular lights I would get those conversion kits that lets you use a normal bulb and use HID's. I hear pulling the DRL fuse in most cases is good enough. I guess the best way is to just pull the relay and see what happens! Quote -Thad What America needs is less bull and more Bulldog!

QCDriver Posted February 18, 2007 Author Share Posted February 18, 2007 The reason I asked is, DRL's use's the low beam at lower volts for DRL.The HID kit's say they need to be disabled. My panel has what looks like a large DRL relay or curcuit breaker (size of a flasher unit). Is this a ECM disable feature? I've been running Xenon bulbs and DRL does not work with these. They don't last long either..What type of lights do you have?? Many HID conversions out there.. Quote Link to comment Share on other sites More sharing options...
Mack 3P Posted February 19, 2007 Share Posted February 19, 2007 Pulling the DLR relay will make your truck think it dosen't have daytime running lights. The part you should be looking for is 116MO33AM, the DRL is to the right of the flasher. Quote Link to comment Share on other sites More sharing options...
Q-TRANS Posted February 20, 2007 Share Posted February 20, 2007 (edited) Usually there is a layout diagram pasted to the back of the panel that covers the electrical ( Fuses / relays ) my CH came with it as well as 8 electrical wiring prints ( very helpful ) of the entire electrical system.The DRL relay is the upper RIGHT relay as MACK 3P notedFLASHER ------------ DRLDIODE ------------- SPARE Edited February 20, 2007 by Q-TRANS Quote Link to comment Share on other sites More sharing options...
QCDriver Posted February 21, 2007 Author Share Posted February 21, 2007 (edited) Thanks all, I knew where it was located, I'm running a different # bulb from stock so DRL's do not work now. I just wanted to make sure thats ALL i had to do, for disable. B4 I install HID's Thanks Mack3P for the info for disabling, I wanted to make sure was not in conjunction with anything else such as ECM.Thanks agian.

Troydye70 Posted June 25, 2023 Share Posted June 25, 2023 Is this the same location on a 2021 Mack granite? Quote Link to comment Share on other sites More sharing options...
vinny933 Posted July 5, 2023 Share Posted July 5, 2023 If you have premium tech tool you can turn them off 0n your 2021 with the computer. I seen it in there haven't done it though Quote Link to comment Share on other sites More sharing options...
Macktruck09 Posted July 12, 2023 Share Posted July 12, 2023 Other than using a computer or pulling the relay (since it triggers the check engine light) is there anyway to shut the DRLs off? Pulled the relay and it throws all the codes Quote Link to comment Share on other sites More sharing options...
Mackpro Posted July 12, 2023 Share Posted July 12, 2023 On the GR , PI and AN model trucks with the new dash you have to use tech tool. Everything is controlled by the LCM light control module. Quote Link to comment Share on other sites More sharing options...
