Default Before/After ABS Well for 1991

I dived into this project already (inoperable ABS) with both feet, but this is approximately what my ABS well looked like. I am undergoing repair of my abs system and looking under here, I hope that's not a factory gm job

I am hoping that someone who has relatively untouched ABS Well would take a picture under the sound cover so I can try to put this back closer to the factory layout.

I've already pulled that harness out, because as you can see, it looks terrible, wire are broken and I get no light at all from ABS on the DIC even though the fuse is good..not even when jumping pins a and g on the aldl.

Thank you in advance. Here's the before pic. The ebcm (computer) is not pictured but is there and the connector was just sitting on top, so it looked plugged in but wasnt snapped in. You may be able to see the positive and neg large power wires are both disconnected and a couple broken wires...so I decided the easiest way was just to pull the harness out and repair it on the bench.



I ordered a manual covering the 90 and 91 system, but it appears I can make some progress at least with a multimeter, checking relays, repairing the broken wires and applying 12v to the abs motor. It doesn't look good right now!
