Kitchen Cabinet, Post #27
With the electric dump valve ready to go I next need to find a way to power it. So I've got the doghouse off and laying on my back looking around under the dash ...
...when I see this unused connector. Wonder if there is something I can use?
Get out my copy of the Ford Econoline "Electrical Vacuum And Troubleshooting Manual". The manual is for the year before my 1999 van but a feature of the Econolines is how little changed from year to year.
Look among the pages that show the different connectors. Here are some of the connectors in the dash.
The picture isn't very detailed but it does narrow it down to these three possibilities. Connectors C232, C215 and C214.
Look up the connector numbers. After some work I figured out it was connector C215. Illuminated Entry Module.
Find the page listing for that connector.
For this connector I see pin number 7 is "Power (Hot in Run)" and pin 8 is "Power (Hot at All Times)". So this means I have now found a circuit to power the electric dump valve from.
My idea is to use the dump valve while the van is running so I'll tap into the "Power (Hot in Run)" circuit. If I was to tap into the "Power (Hot at All Times)" circuit I could possible operate the dump valve by accident while the van wasn't running. Not what I had in mind.
Next check the schematic for this electrical circuit. I want to make sure nothing else is using it.
Looking back at the connector picture it lists the circuit number as "296". This photo is a closeup of circuit # 296. It shows the circuit running from a shaded box at the top through connector C201 then to connector C215 then into another shaded box.
The top shaded box represents the fuse panel below the instrument panel. Notice the number "24" and the designation "5A" in the box. This means the circuit passes through fuse number "24" and the fuse should have the value of 5 Amps. The shaded box at the end of circuit 296 represents the Illuminated Entry Module but my van doesn't have one so for me the circuit just ends. Also notice how no circuits branch off anywhere between the two shaded boxes. That means nothing else is sharing the circuit so I can use it.
Now this is the first time I've used the manual like this so I want to double check I've got it right. The connector illustration shows the wire color as "(W/P)". The first letter is the solid wire color and the second letter is the stripe color. In this case that's solid White with a Purple stripe.
Double check that the wire supplying pin position #7 is white with purple stripe. It is.
Use a voltmeter to check that there is 12 volts on that pin with the ignition switch in run and zero otherwise. It is.
Final test. Locate fuse #24 and remove it then check the circuit. Here is the illustration for the instrument panel fuse box. Fuse #24 is third from the bottom on the left.
In this picture you can see a 5 amp fuse in the position marked as "24".
I removed the fuse and checked the circuit again. It was dead this time. OK, I'm convinced I got it right.
Cut the wire from the back of the connector and splice on another length of wire.
Mark the wire so I'll know what it is.
Connect this circuit and a ground wire to opposite poles of a Double Pole Double Throw (DPDT) three position (ON-OFF-ON) toggle switch.
Run two wires from the switch, under the door jam, along the edge between the cockpit and raised floor and under the side cargo step.
Add male and female disconnects to these wires and the ones from the dump valve.
Hook them together. Replace the 5 amp fuse I pulled from position #24 in the fuse panel with a 10 amp fuse. Test the valve from the toggle switch.
Open the valve, Close the valve. Open the Valve. Close the valve.
Considering all the thought, time and effort it's taken to get to this point I can guarantee that this will never
When it's time to install the dump valve under the van I can run the control wires through this already provided access hole near the Webasto heater on the cargo step.
Install the greywater dump switch in the dash.
That ends my work on the kitchen cabinet for the time being. Once the cabinet is installed in place it will restrict access to the van so I'm holding off on the final install till I finish a lot of little jobs been putting off till now. Will start writing about them in subsequent posts.
Now if you'll excuse me, there's something that needs doing.
Open the valve. Close the valve. Open the valve ........
