Help!..m i missing a part?

[Nyborg]

New tank in,pump,filter ,gas etc...cranks over but won't start..Have spark,hear fuel with fp and b+ bipass.Power at injectors with key on..will check for pulse next..My problem is that it looks kike i'm missing a harness or relay near the brake booster.In the pictures there is a two wire plug that comes out of the main harness along the firewall near the master.I've seen in other pictures something plugged in there.This car was in storage for a while..fi resistor and boost sensor were missing when i got it.Maybe something else is gone.The wires are yellow w/black stripe and white.............next step is to remove an old 8026 alpine alarm!..@#$%^&*.....any help greatly appreciated.

That plug goes to the horn on the firewall next to the brake booster.
Not important for engine operation
Though the horn wires were probably hacked into for the alpine alarm system.

Hey, I am new to the supra world and just got my car firied up last night and I had posted on here that I cant find where that plug goes to either, I have no power at my fuel pump relay on the passenger side fender with the heat Sink (which should feed your pump 8 volts at idle and 12 @ wot) I have my pump wired direct to 12v and it runs this way
