Headlight switch
Headlight switch Is there any way to disactivate the computer from turning on my headlights at night. Sometimes i want to roll with just my fogs and parking lights on. Any help will be greatly appreciated. Thanks.
Pry off the radio bezel and pull out your radio. Behind it there's a small box with two plugs into it (black and blue) i believe you can remove the blue plug to do this. I was going to wire a switch to turn the automatic headlights on/off at my will, but I ended up shorting out the module, so now they just turn on randomly.. heh. Remove the blue plug and you should be fine.

The safest way to disable the automatic headlights is to make the system think it's daylight all the time. You do this by shorting the two sensor wires together (0 resistance = daylight). The easiest way is to use a scotchlock connector and just crimp it onto the two light green with black wires at the sensor. If you want to go back to stock later it is easy to just remove the connector.
The hatch release disable is only for manual transmissions, it stays active by removing the plug, and I forgot about the break light issue... which can be vital. I had forgotten about messing with the light sensor, it's under your dash pad.
Well as far as I know, the brake light comes on when you're low on brake fluid, too... so it's not something I would just get rid of. You can do some hardware modding, by soldering two points together on the PCB of the module, but I wouldn't reccomend that, you risk shorting something out (like me..)

On M6 cars the hatch release relay grounds through the DRL module and the parking brake switch so it will release in any gear as long as the parking brake is engaged. Unplugging the blue plug at the DRL module disconnects that ground so the hatch release won't work at all.
I pulled the radio as far as possible and looked for a box with two plugs all i could find was a pretty bix box like 3 1/2" by 2" with two pugs with alot of wires on them. One of the pugs has a bit more blue than black but they both have blue and balck. Is this the right pug im suppose to take off? If possible can you show me some pics. Thanks.
Oh and i also want to switch my radio from my camaro to my Astro van because my cd player doesnt work. They look exacly the same do i have to cut every wire or is there someway to pull out the big pug? Thanks.

The DRL module is a black box about the size of a pack of cigarettes mounted to the defroster duct behind the radio. It has two plugs - one black and one blue. The black plug has eight wires - orange, light blue, dark blue, red, light blue with white, yellow, dark blue with white, and brown. The blue plug has seven wires - black, pink, tan with white, light blue, brown, light green with black, and yellow with black (except Firebird convertibles where this wire is a second light green with black).
Since you're already there you can short the sensor wires at the DRL module rather than at the sensor to disable automatic headlights. Simply crimp on a scotchlock connector to the light green with black and the yellow with black wires so that they are shorted together. They're right next to each other so this should be easy, it can easily be reversed by removing the scotchlock connector, and it disables the automatic headlights without any side effects.
As far as your radio swap, the radio from the van should plug right in as long as it's not from an 03 or newer model. On the back of the radio you will find two ten pin connectors hooked together to look like one big 20-pin connector. Just squeeze the locking tab and pull out the connectors. Then pull out the antenna cable and swap in the new radio the same way.
