Posting on here again as most people to post the fix or the solution to the problem.
I went ahead and re-inspected every cable involve with the connection before disconnecting the battery.
Then I saw one brown wire connected to a plastic piece with a fuse inside. Right next to that fuse there was a hanging brown wire
and put 2 and 2 together and realized they both needed to be connected to the same fuse.
voila problem solved, although its a tiny wire, and hanging alone sort of looked like a ground wire, but to the trained eye
it should be a no brainier.
to a noob like me, it took about 15 mins of investigating the wires.
