john,
Its the iron one. I looked at the AL one and same issue, not enough ports. what are your thoughts?

The t-stat extension sounds interesting, it is under the stat so I should get a pretty good idea of block temp, there should be enough turbulence there to allow an accurate reading. Gonna go look for it
