Try connecting the wires & see what happens. I think it'll constantly show hood ajar. I also don't think that switch is tied into the alarm. There is a switch at the trunk latch that'* part of the alarm. Try unplugging that .

Hmmm...this morning, the car wouldn't start. No power. I tightened the battery cable one more 1/4 turn and it worked. Perhaps that is the problem.
Aside from that issue, I connected the two wires and the hood ajar message stayed on constant, which is better than off, on, off, on bling, bling, bling the whole hour ride to and from work.

Just tried finding the hood ajar switch at both AutoZone and Advanced Auto parts and neither had it. I saw on GMpartsdirect they had an "ajar swtich" 25620933. The connector is bad and I also broke the plastic actuator getting it out. Is this part for the actuator or the connector or both?

Also, I never addressed the security light being on:

Could this faulty connection cause the alarm to trip and/or the security light to be on constantly? After tightening the battery cable, I've been using the FOB to lock the car and have not had it go off yet (knock on wood). I read in a post by Willren that the hood ajar sensor is not tied into the alarm, rather the trunk lock cylinder is. (P.*. - what is VATS?)

Looks like it might have been the battery connection because it hasn't gone off since I tightened it.

EDIT:
As for the hood adjar sensor...I ended up going to the dealership to get the parts. GM said the connector was part # 88987993, which lists for $99.80 !! Lucky for me, the parts counter guy accidentially bent the tab back too far while testing for fitment. I got it at cost $45.37! For the actuator, I just super glued it back in place.
I should've just gone to the junk yard.

Thanks for the advice!!
