DCC Help

[okinawa drift]

just purchases a digital climate control for my s13 and it wont power up for some reason.. i did everything the write-ups said..

i spliced the red wire into my red/black wire with my radio..

i spliced the blue/red wire to my blue wire along with my radio...IGN+

i spliced the green/white to the blue/orange..

and red/orange to ground ..

anyone have any ideas? maybe a blown fuse? where could the fuse be? inside? or under the hood? ...

I've heard sometimes DCC control unit itself goes bad too.
