RB headers in gsl-se 13 fi

[drive_4_thrills]

i just got all my gaskets in so id thought to update on my exhaust project. Last night i took the exhaust manifold and piping off. I test fitted the headers and it seems i had welded the 02 sensor to close to the fire wall so i got to get that corrected.

so when i get every thing on i wont have the 6port tube hooked up until i take it to a muffler shop. I wanted to be sure that i have a couple things correct.

In the following pics i have in red is were the actuators got its pressure so when i wire open the 5th and 6th port do i need to plug that hole?

And in blue and yellow is were i actually wire them to stay open?

i should have every thing bolted on this weekend. Later i have to grind some bolts off for the muffler but besides that im thinking its pretty strait forward.
while i was down there i noticed my omp is leaking, is it common for the part to go bad or is it just a seal? im headin to mazda today to order a couple other gaskets so i can check the availability for the part/gaskets.
