1985 22r - where do these 2 vac lines go? (pics)
I just got my newer motor (86 22r) installed in my 85 and for the life of me, can't figure out these two vac lines...
First one:
I don't even know what this sensor is, couldn't find it in the FSM. has a #1 on the line, about ~12" long
Second one:
bottom edge of the air box. Had a ~6" line on it, so I know it wasn't the line in the first pic.

Ok, I figured out that the line on the bottom of the air box goes to the second line from the top on the VCV
However, I now have another vac line with no home.
It is the line right next/below the circled one in this pic:
I can't even find this sensor anywhere in the factory service manual for my 85 truck. I have stripped the 86 truck that the 22r came from but I don't see that there was ever a sensor like this on that truck.
Does anybody know what this sensor is? It has a little charcoal filter one one side and 2 vac lines on the other side. I need to know where those 2 lines go.
There's a 2-wire plug going into the sensor with a blue and a back/red wire.
Hopefully this truck will be starting today!

looked again at pics I took before I toook it part and figured out that this sensor ran inline between the vcv and asv. got everything hooked up nw, but still wont start. if I pour gas in carb, it will fire up and run if I keep giving it gas. I'm about to give up for today....

The valve in your first image is the VSV (vacuum switching valve ND 084600-3310 ). If you have a/c, the line closest to the valve body connects to an idle-up actuator on your carb, the other line attached to the L-fitting connects to a hex-shaped fitting on the intake manifold under your carb.
If you don't have a/c, check out this link for diagrams--http://www.pirate4x4.com/forum/showthread.php?t=579557
The vacuum line coming off your air filter housing connects to a sensor valve attached to the thermostat housing. The valve has two fittings, your vacuum line from air filter box connects to fitting closest to thermostat housing.
Hope this helps

I got all the lines and it still wasn't starting unless I poured a little gas in the carb and then it would die if I didn't keep giving it gas. Float level was good. So I put the choke from my 85 on the 86 motor and it was the same thing. So I put the 85 choke back on the old motor took the entire carb off and put it on the 86 motor and it fired right up!
