Is there a trunk release button in the glovebox?

unplug the switch

I know of the remote battery under hood on the left side, I have located the positive cable connection, and the manual states the negative cable connection is near the power steering pump.

But my question/problem is I need a specific picture of what the the negative cable connection looks like can you provide me a visual on this?

Check your strut mounts, and front struts, my 2004 cadillac deville did the same thing between 67 and 75mph and after time it shook between 58 to 80mph, and it was the front strut mounts were egged out, and front struts were weak. I had my tires balanced, wheel bearings replaced, and it didnt help.

Hello: The noise is from the air pump. This pump puts addition air in the exhaust to help burn the extra gas the engine gets when it is cold. If the pump is extra noisy it probably needs replacing. It is located in front of the drivers side front wheel. You have to remove the bottom splash guards to get to it. It may be a dealer item only but you can check with aftermarket stores to see if they have it. It is normal to hear a low whistle when it runs. Does not run very long.

may need to replace gas cap

SECONDARY AIR. CHECK VACCUM HOSE AT VALVE ONTO OF WATER PUMP OR AIR PUMP ITS SELF (WATER INTRUSION) IT'S UNDER AIR FILTER BOX, ACCESS FROM UNDER CAR

Cadillac Northstar owners to those whose vehicle is overheating .My 99 Deville was overheating turns out it was Catalytic Converter.Dont rely on PCM for code.If the Cat converter gets plugged up the heat will not get past converter it will back up into engine block causing overheating.My deville ran at between 190 & 201 degrees this morning.If you have a misfire the unburnt fuel goes into Converter and causes damage to converter (blockage).Alot of people overlook converter when overheating happens.

How old are the spark plugs ?

Analog or digital gauge ?

I would almost bet that your issue is the small wires that run from the lock cylinder down the steering column. They are known to break right at the lock cylinder. You have basically 2 choices. You can replace the lock cylinder and have the pins in the new one changed to accept your factory key, or you can bypass the PASS Lock system and have a set of resistors installed into the factory harness under the column. If you choose to bypass the PASS Lock, I suggest contacting an audio shop that installs remote start systems.
