How to wire secondaries Eg/GSR Hybrid?

[Hybrid93Hatch]

I tried all day to wire my secondaries up in my Eg/GSR.

The car would not start because the 15amp ECU fuse was blown. Still can't get the secondaries to work.

WHAT I TRIED SO FAR:

1) Black IAB wire to B1 at obd1 p72 ECU - blew the 15amp ECU fuse
2) Black wire to junction power harness - blew the same fuse again

93 Civic Cx
98 GSR motor (usdm)
OBD1 p72ECU

I am thinking there is another wire spliced in under the loom / electrical tape to this black wire which I believe is a ground? I spliced in close to the shock tower and maybe need to splice in where the wire comes out the IAB. I've already made 3 cuts in wires that turned out to do nothing right at this point. When I took my Cx harness out I took most of the loom / electrical tape and there were wires spliced in underneath it all. I'm thinking the same is done on this wire causing a short / blowing the ECU fuse.

Here's how I tapped in for 12v. Going to use the same connection, but move the splice down right where the IAB sensor is. This is a source for 12v, right?
