Wiring harness install. No power?

Hello, I just got a w/s harness made for my jdm S14 kouki Rb25det swap. Ive got the harness installed however today when I went to put the terminals on I just received a mildly violent spark on the battery cable, and no power. I am confident that nearly everything is in the correct location exept for the Starter/Alternator/Fuse box setup. In the pro harness instructions it says to bridge the possitive terminals of the alternator/starter together so I did that. I also have a ring terminal that is supposed to power the harness on the positive end of the starter, as well as a direct power feed from the possitive battery terminal to the starter. This seems to be what is described by the instructions on their website. There are no ground wires on the starter/alternator. Is this normal? Also if anybody has a picture, I am interested as to where the ground/power terminals run within the fuse box. Thank you very much in advance for any answers.

Heres how the fuse box looks, I suspect the problem lies here. Does anybody see anything out of the ordinary or know if that plug coming out of the back if of significance? I could not find anything on the harness that would connect to it however may be mistaken.

My car is abs however the abs harness I got did not come with a long enough wire to reach the speed sensor located below the fuse box. This would not interfere with the vehicles operation, would it?

I have tried using booster cables to ground the starter/alt/block in many different ways. all to no success.

Help please, im so lost! Ecu/F3/Abs/Interface plugs are all attached aswell.
