parking light on econoline

I am currently starting to install an alarm system on a 1997 Ford
Econoline. I have found the parking light wire which is brown colored (and according to info here at 12volt.com it should be brown + ) along side the driver side kick panel and extends backwards towards the rear of the van. It shows +12v when the parking switch is on but when I tried to apply +12v to it, I can't get the parking lights to turn on.
I looked behind the switch and there is no equivalent brown colored wire.
I think it is a very simple thing I missed but on a previous import I installed an alarm system in, I simply applied +12v to the parking wire and it turns on.
If anyone can point me to the right direction as to how to tap into it to make it turn on I would really appreciate it. Thanks.

It should be a Brown (+) wire in a 6 pin connector in the Drivers Kick Panel.

Does your R/S parking light output supply +12v at 10amps?

I found the 6 pin connector with brown wire also and it tests the same just like the other brown wires.

Is R/S Rear and side ? The rear and side parking lights do supply +12v but I don't know what amperage. How do I test for amperage?

Sorry, I meant does your alarm control unit output a +12v Parking Light output rated at 10 amps?  What brand & model alarm?

The Brown (+) parking light wire in the car might need the  10 amp rated current output.  When the alarm parking light signal is attached to the correct wire in the car it should turn on all the lights that the normal parking light switch does.

The alarm is an Avital 3100L. It has + or jumper adjusted - output for light flash. The instruction says i would need to switch it to - if the vehicle requires a - output or if the parking light circuit draws 10 amps or more (which needs a relay ).
But I haven't gotten as far as to connect anything to the alarm. I am just testing for the parking light wire with a voltmeter. And also apply a + current directly to the brown wire so make sure the parking light comes on. So far there is no response when I do that. Although when I turn on the switch for parking light, the light comes on and I can measure +12v on the brown wire.
Basically I can't turn on the parking light when I give the brown wire + current.

I recently installed a remote start into a 2006 Ford Econoline.  I used the Brown (+) wire at the headlight switch and it  worked fine.  The remote starts Parking Light output  was rated up to a 10 Amp draw.  Your van is probably similar and your alarm is capable of a 10 amp, +12v parking light output. 

Please excuse the dumb question but ...   When I do a test like you are doing, I use a 20" wire with aligator clips at either end and an ATC fuse holder in the middle with a 10 A fuse installed.  Are you sure your test wire is supplying a good +12 volts  to the correct, DMM verified, brown wire? 

I know you already checked but, according to AudioVox, there should be a Brown (+) Parking Light wire at the vans headlight switch also.

Thanks to your last post (and definitely it wasn't a dumb question, since I am the one who is a rookie at this), I rechecked the testing method and found a very elementary mistake.I finally got the parking light to turn on when I applied current to the brown wire. I did use a fused long wire but at the testing end I used a test light to do the actual contact with the brown wire. When I repeated it with only the long wire directly to the brown wire, the parking lights turned on. I won't make that same mistake again.

Also I found the brown wire at the light switch. I mistaken it for a black wire earlier and now with proper lighting it is definitely brown.

After that, I wired up the alarm's parking light output to the brown wire and also connected the constant +, acc +, ground, and led accordingly. Once power was given, the led was lit. But when I press the remote, the parking light didn't flash and the unit seemed to turn itself off. Then I disconnected power and reconnected it and it did the same thing when I pressed the remote. As you mentioned in the last post, my alarm is capable of a 10 amp, +12v parking light output so I shouldn't need a relay for it.
I am not sure what I connected wrong yet but it was getting late so I will recheck tomorrow.
