Default Can't find male plugs. OBD2A D15B7-Y7 head swap

Hey guys, I'm having a bit of trouble, when I pulled my motor, I pulled the harness as well, and after putting it all together to drop back in, I can't figure out where the last two female plugs are supposed to go to.



These are the plugs, very large and significant, as you can see, hahaha, and I couldn't see anything from the Y7 that they plugged into either. I infinitely regret not taking pictures of this mistake beforehand. Can anyone help me out? I swapped a Y7 head onto a B7 block.

What car is this in?
Is the motor back in the car? I am not sure just by looking at the plugs, but you can't really get the connectors mixed up. When I replaced my motor it was just a matter of finding the correct plugs once it was back in the car. The harness lays out a certain way so it will kind of guide you to where it is suppose to go. The reason I ask what car is because you could have some unused plugs going from OBD2 harness to OBD1 car/block.

Those plugs are dead end/junction plugs. They have caps that go in them. Here's what they look like and what should be in them.

Hahaha alright, thanks guys, but if those are dead plugs basically, then do you know what could be causing my instrument panel to light up rhythmically to the sound of my signal clicking when I connect the battery? signal is off, the clicking happens on its own. Could I be missing a plug, or have a bad ground, or need the caps for those dead plugs?

the one dead end plug is to your injectors if using a resistor box u can wire it into it making a plug and play harness.
