I've just bought a 2000 PY ITR with JDM engin in it

I was going tru the engin bay and i've found 2 plug unpluged :


The terminal on one as a round form with 2 wires
Location : it come from a 2 wires harness juste betewn the intake manifold ant the firewall. The other set of wire plug into the intake manifold

- one yellow with a black line
- one red with black line

The other one is square ans is locate mor toward driver side. Came from a three wire harness

- one is white with red line
-one is blue with red line as well

The car is running find without it...... I just like to know what use are they for...

Thanks

 

Pictures would help.

and there are a bunch of unused plugs due to lack of options in the car.
