Help identifying B5 connector/wiring - 1990 Hilux Surf LN130G 2L-T 2-door

[Bankrobber5]

Hoping for help figuring out what this plug connects to. Seems to be attached to the main dash harness, I believe the previous owner has tried to bypass a module and it has failed at some point. It's a 1990 2 door ln130g 2lt. If anyone knows what it plugs into or has a wiring diagram showing it id appreciate the help. Thank you
