Electrical Issue

[gstjoker]

I recently installed the evo3 16g and greddy 24r fmic onto my 2g gst. After everything was installed, the battery died, so I took it off to get it tested and recharged. The problem that I am getting is that my power windows, door, the defroster function, ac & heat wont come on. All of those I had just stated worked fine before I did the installation and the only electrical thing I did was disconnected the battery. All the fuse were checked and they were all in good working condition. Does anyone have any idea what could be causing this problem.

For some weird reason, when I turn on my headlights when the car is not on, the horn will honk, but if I turn on the car and turn on the headlights, the honk doesn't come on. Let me know of any possible solution to this as my last resort may be taking it to a shop to deal with it.
