I found an H.L. Controller in the box containing my 1GGTE (GA70) loom. It is not plugged in to anything in the loom but does have auto elecrical looking plugs
On the top is a control with the labels 'H' round to 'L'.
The small writing at the bottom says Nagai Industries.

I'm no expert on finding the right size, but there is definately such a thing as overkill. If your IC is too big then you'll get much more lag than you need to due to the increased volume that needs pressurising.
