Vacuum line for heater blend

[Smurfeh]

Hello again,

I know I've been throwing down alot of questions lately.I've managed to do 1 build with minimal questions and am almost complete my second build. One thing I noticed about the first swap that I want to correct with the second swap is being able to use defog.

I dont notice it much on my 1st one, because I use an internal heater in the cab while it is parked overnight. So its always defogged and warm inside for me when I jump in. However with two trucks it would be a major draw on the houses power.

I know that the blender lever for moving the heat from the floor to defog is vacuum controlled.. and I would like to know what you guys used as a vacuum source to drive that heater mixing valve. It would be nice to have that working and save a bit on the power bill.


Also, as a second question.. I'm still waiting for my second harness back and ECM..I sent it to current performance. anyone know what to expect from them when I get it back? quality?

Once again thanks for your time guys.. you know.. its winter and all.. gotta keep your fellow members warm
