Alright lads.

I'm looking for a bit of advice on for plumbing my cossie cortina.

I'm using a 2wd thermo housing, turbo cooler and a 3 port bailey header. I have plumbed so far as follows;

1. Turbo outlet to turbo cooler inlet
2. Turbo cooler to header small inlet (top)
3. Water pump outlet to lower rad
4. Thermo outlet to top rad
5. Bottom header to lower rad stainless pipe

Question is....where does the middle inlet pipe of the header plumb?

See pics below.....have I plumbed correctly?? Do I need a 4x4 thermostat housing?
