It's Renix, and it may just be the connector but it definitely looks "broken" on the end. It is the only line going to the MAP, and from what brief internets search I've done, there should be a port on the throttlebody. There is a rubbery, plastic-y "grommet" (for lack of a better word) on the "inside" (facing the motor) surface...this could be where it goes, as the bottom hole seems "almost" the size of the little plastic nipple. I may need to replace that whole grommet-y thing? Apparently that's the vacuum port for the thing, but if I've broken off part of the plastic connector I need to figure that out, I guess, before I proceed...I'd really rather not be taking my throttle body apart but if that's what it takes...
And I don't think there's going to be any need for ECU adjustment. The stock injectors are 18.6 lbs/hr, my "new" injectors are 19 lbs/hr. It may run a little rich, but apparently the Renix system is a learning one, that actually listens to the knock sensors and adjusts accordingly. If it is too bad, then modifying the map sensor is apparently fairly straightforward to allow for adjust-ability of the MAP to add/remove fuel. Obviously not something I'd want to do on, say, a turbocharged car, but for an N/A truck motor if I need to trim the fuel, it'll be easy.
