Engine wiring harness, got rid of the uneeded plugs, air pump delete on my 07, 2x TGV plugs per side, and the air check valve that runs from the pcv to the turbo inlet. Also wrapped the gray part in black now.

I tried to do a wire tuck but Geez there is no room under there.

This is what came out.

Also deleted the oil heat exchanger to fit my EL headers on my 07 wrx.
Pulled the nipple from the waterpump and tapped it for a 1/4 npt plug, I guess next go round I'll just order a 08 wrx pump.

Also order the OEM plug for Legacies and what not without the heat exchanger and removed the nipple by the oil filter.

NEXT UP: temp switch on the I/C to controller the sprayer.
When the oil is 220F and hotter, then 180F coolant will cool the oil. Hence "oil cooler". It does double as an oil warmer when the oil temp is less than the coolant temp, but that is a good thing. Your engine is designed to work with oil that is hotter than your coolant [over 200F].

It is a BAD idea to not have an oil cooler.
