Wiring connections identification

[kerchew]

I have a few wires with connectors I'm trying to figure out if useful or not. Or if they even connect anywhere. Mind you the truck runs. Thanks in advance

Sorry didn't specify year.
1985 4runner 22re. Tach cluster is modded for brightness and rear window has the mod for two wires instead of stock

I think one of those connectors near the cluster is for the x-tra cab's rear bed light switch.

And I think the two by the oil pan are for diesel injectors or glow plugs, but don't quote me on that. I have the same ones on my wiring harness, they don't go to anything on my '87 x-tra cab with 22RE and 5sp.

Ah thank you. I guess the 4runner and hilux do share the same wiring harness so that makes sense.
