Hi everyone. I'm installing an air grabber on my 70 Roadrunner which is not an n96 car. I have the hole drilled, in what seems to be the factory location, and now I'm to the point where I need to drill the smaller holes to attach the switch to the metal dash.

I have not found any good reference as to which way the switch should be installed. I know there's an on and an off to this and I don't want to take a guess on drilling the holes for mounting.

On the back of the switch there are three vacuum ports, the vacuum port closest to the outside of the switch is my guide. Does that go on the left or right hand side of the car? Based on the little drawing that I have,

I would guess that third port would be on the right hand side?

Thanks for your help,Bill

Bill,
First thing.....this is a VALVE not a switch....just kidding...everyone calls it a switch. The vacuum SOURCE gets connected to the port with the small restriction. In my origional RS23V0A***** N96 GTX, the valve is installed that when the handle is in the UP position, the air grabber will raise automatically when the ignition is ON and engine is running. There is a small 12 volt DC solenoid valve located on the back side of the dash on the top side of lower ridge. This solenoid vents the vacuum to the air grabber actuator, allowing the air grabber door to close when powering down. The purpose of the dash board valve is to prevents the air grabber door from opening when it's raining, preventing rain water from saturating the filter element.. The under dash solenoid valve is probably the most overlooked component in the N96 system.....its relatively expensive approximately $150-200. It gets connected to the ignition ON wire going to the ballast resistor feed. The air grabber actuator is available as REPRO for approximately $ 200 (+/-) from several sources as well as the closing solenoid valve.

Yes you are right, it is a valve. I keep calling it a dang switch.

Anyway, I have all of the components including the solenoid and the valve in the picture and dash is of my car. Like I said, I'm sure there's a certain way this valve is positioned in the dash as you have the three areas on the back of the valve to attach the hoses. My dilemma is drilling a couple of holes in the dash to attach the valve. I don't want to drill the holes and attach the valve to the metal dash only to find out it's upside down and now my holes are off. The holes in the valve to attach to the dash are slightly off from one another and different sizes. There's got to be a right way and a wrong way. Who knows, maybe I'm overthinking it. I guess if I'm wrong I could always enlarge or oblong the mounting holes in the valve.

Since the valve is mounted thru the dash, and secured with screws, you can always enlarge the mounting holes slightly to accomodate the valve should it requiring reorientation. The important aspect is when installed, the valve handle is UP to enable operation and look correct.
Remember also, when installing the underhood air grabber hardware, that you will need a three (3) speed wiper motor to clear the air filter base. The three vacuum hoses connecting the valve, solenoid valve and vacuum resevour supply pass thru the firewall with a rubber grommet to seal. There is a bezel that should cover the screws. The FSM shows the correct orientation of all the components, including hose routing and vacuum connections. You will also need a manifold vacuum fitting.

Sorry, I get what you are looking for, does the single port go to the right or to the left. I will keep checking.

Yes that's exactly what I'm trying to figure out. But, if the image you posted is correct (the one with less detail) , shows the single port on the right hand side of the vehicle. That's what I'm going to go with.

Thanks guys, Bill

I'm trying to remember but I believe that the port was on the right side. I guess you know once you plug it in and figure out if lifting up on the valve handle raises the scoop.

But I tried 2 brand new valves and both leaked. I tried to fix them and just decided to forget about it. I came up with an awesome solution that I posted online. You can find it here:

The drawing shown in #6 is a PICTORIAL representation of the hose routing of the vacuum lines. The PHYSICAL orientation of the Air Grabber VALVE.....left/right - up/down...is not as important as the correct connection of the hoses. Since the origional valve toggles up / down to operate (not side to side), UP for automatic operation places the single port of the valve and positions the valve body to the RIGHT.
