Help with estimating VECM

[econometricz]

This is the first time I am using eviews and estimating VECM also for the first time.

I have 8 price series.

I test for unit root.

If they are I(1) then I proceed to test for cointegration.

If the number of cointegrating vectors is 3 and I need to estimate a VECM, how do I proceed? There are many options in VECM model, which one and how should I choose? I tried putting number of cointegration vectors = 3. So I get a huge output. I need help with interpreting the output too.
Part of my output looks like this:
