Anyone out there successfully disable their DRL? The simplest way is to pull fuse #15 on the IP, but that will disable my factory fogs as well (on Denali)... I also tried pulling the black finned DRL box under the IP near the right side of the steering column... and this disabled the DRL...

I looked through several repair manuals (Chiltons, Hayes, etc .. I don't have factory manual) but they don't have much info on the batch of relays under the drivers side dash (IP)... the ones near the parking brake... Any info on that would be greatly appreciated. When I turn my parking...

Hey guys.. I know some of you have electric fans... and some of you have manual overide switches to turn them on... but has anyone hooked up the AC turn on line successfully to the AC? I have the PermaCool fans.. (they're awsome) and wanted to hook up the AC turn on wire (blue wire) from...

In case you didn't know, MSD makes a direct fit coil upgrade. In my opinion, the overall MSD package works well... I've had mine for many yrs, and had better mpg, as well as smooth idle, and instant starts. If I had another truck.. I'd get this again... in fact, I've installed MSD ignition...

OK... i just got to fixing my horn, which got me to take apart my st column.. which made me think about my high-beam problem. My high beam went out many yrs ago. If I pull the stalk toward me, I hear the click, but it does absolutely nothing. No high-beam... not dash indicator, etc. At one...

Anyone here do a GM Hydroboost brake conversion? I heard they offer awsome brake feel and stopping power. It's a popular upgrade of offroad rigs, and standard on some of the diesel trucks/suv... So far I've heard it offers 2-3 times the brake pressure... great for upgraded calipers/and disk...

Anyone swap out the oem distributor for one w/ an aluminum lower housing? Supposedly, the oem plastic housing strips easy. Reason I ask, is that I will be changing my cap/rotor soon, and wondering if I should upgrade it. Some people say that this can help the "hot engine/no start issue"...

Has anyone installed the "updated" injector setup in their 5.7? I had my original injectors serviced around 100k when a couple went bad (common) and the tech told me that there is a new warranty... for 10 yrs/200k miles... if your injectors go bad, then GM will "update" the injectors. The...
