OK so I started my rebuild project a month ago, working on it after classes and work and I need some help on two harness I cannot place.

The car is a '95 Celica ST (California)

Both wires are on the intake side.

1. On the same wire cluster as the downstream 02 sensor, and a lead to a vacuum control switch.
Two prong connector (black/red and brown wires).

2. Out of the injector wire harness (the solid black plastic box under the intake).
One prong connector (blue-ish wire).


Can anyone help me with what these goto? I've been staring down there for an hour or so and cannot see any clips that need a harness.

Also if anyone knows where I can find some good information on the vacuum line routing (EGR, EVAP...etc.) and wire routing could you please post it?

Thanks for your help in advance.
