I'm presuming the DME Relay is dead. I'm hoping the DME itself is not. I'm unsure if the shorted Coil wires would kill the Coil and/ or damage the DME.
From what I can see, the front fuse box is ok. The impacted wires appear to be limited to the DME/ DME Relay.

The short went thru the DME relay, power at 30 to 87b to the fuel pump, O2 sensor heating. Hopefully that and the ground wires bore the brunt of the current so the DME's unscathed.
The power to the coil comes from the fuse box. Have a close look at the black wire at the top of the fuse panel at 7 and 8, pic from my 87 your 84 might vary slightly. One of them goes to the coil, part of the 173 harness.
