Quick question on wiring regarding altitude compensator and other stuff.

Finally getting closer to finishing my two side by side swaps and pretty much have both engines ready to go into their respective cars just need to get both engine bays prepped to accept there new motors.
Does the altitude compensator on the filter have power running into it at all times when the car is running? Reason im asking is because the vehicle that is getting the ecomotor dropped into it needs a connector spliced into it somewhere to power the pcv warming deal between the intake and pcv so if that connector on the altitude compensator does in fact always have juice id like to use that.
Being that I had an altitude compensatory on the na motor i have it has the aneroid pump also on this pump is an extra cylinder (on the front facing side of the pump) a little shorter than a roll of nickels with a single blade connector on it. Do i need this? What is it for?

alt compensator is on below ~6000 or whatever feet.

For clarity, I think what you are saying is that you have two engines going into two different cars. One engine is an 1.6ECOdiesel and the other is a late 1.6 non-turbo that came fitted with the altitude compensating nonsense. Am I correct so far? If so, then fit the ECO pump to the non-turbo engine (better yet get a 9mm non-turbo pump) and fit the altitude compensating pump to the ECO engine. Plumb intake manifold pressure to the top fitting on the aneroid. Leave the bottom fitting open to atmosphere. Enjoy the extra power of the boost enrichment. Be sure the exhaust is not catalyst equipped or else adjust max fuel for minimal or no smoke. Throw all the extra altitude compensating bits into the recycling bin a push slightly less hard on the accelerator when you are driving around above 6,000' in elevation.

that piece is only necessary when it is REALLY COLD outside.. think northern canada...
i wouldnt even hook the breather heater up..

I don't think that's accurate. In the same way that increasing air pressure increases the temperature, reducing pressure will cause the temp to drop. Certainly ambient temps factor in, but the pressure drop from pressurized crank vent tube to negative pressure between the air filter and the turbo will cause a significant drop in temperature. Even the ambient air will drop in temp from before the filter to between the filter and turbo due to the reduced pressure. I would think that to avoid forming ice crystals you would want that crank vent heater working any time the ambient temp was below freezing or even a little above.

if it was soo important, why did only a small percentage of cars get them? and why did they only make it to the COLD climates? ive NEVER seen one on a USA car before..

The motor in question was purchased and lived its life in south Carolina until about 6months ago.

That's all it takes to convert a ALDA pump to be a TD pump?

I was thinking the ALDA pumps were 8mm not 9mm, but I don't know for sure. You could check that with the numbers on the side of the pump.

Altitude compensating pumps were 9mm. Only the 1.6ECOdiesel pumps were 8mm.

The boost pin and spring rate are different, but the alt comp parts will work.

Ah, I knew it couldn't be that easy. So this would be a mild TD pump?
No adjustment to the screw on top of the LDA is necessary?

That altitude compensating pumps had the screw on the top of the aneroid, but it is not needed. Any adjustment point there can be achieved by modifying the starwheel, max fuel and idle screws.
