Default 89 civic #12 underfuse keeps Blowing

I got an 89 civic 4 door b18 swap obd1.
I recently got another 89 4 door donor car
i swapped out the whole underdash/cabin harness to my 4 door.

Hooked up everything and the fusebox. Turned on the car i saw a flash under my car where my fusebox is at.

found out #12 fuse blew.
put it another fuse there and it blew right there on my face. it sparked.

tried it again with the car off and battery disconnected.
nothing happen, put the battery back on #12 fuse blew again -_-
cant seem to find the prob why its blowing
tried changing the fusebox still the same

Does removing the integrated control unit prevent the fuse from blowing?

Check the Wht/Blu wire for damage/shorting at the rear of the radio, cig lighter, clock, and interior lights.
