dei tech tip 1923

Is there anyone who can share this with me (us)? It has to do with utilizing the optional LED and Valet switches with the new Viper 5901 that no longer has the connectors in the module. Any help would be greatly appreciated.

I'd be interested to know this too.    I think i read somewhere that pink+red   is for LED    and gray+red is for that valet switch (or the opposite)   but i can't find that post now! i think even it was on some other forum.

i thought i'll post viper antenna module internals, just for a reference:


The plug has 6 pins, i assume red is +12   and one must be for Valet switch, and one for that bright blue LED.   Actually i'm planning to extend my cable a little bit, i hope it won't affect the range of the antenna.

Cut the Gray and the Pink.

Gray from Valet to the grey from the plug.   Black from the valet to Red on the plug.

Blue from the LED to the pink from the plug.  Red from the LED  to red on the Plug

Just that simple.

Thank you very much!

One quick question Mark...are you simply tapping into the red wire for a power source for the optional valet and LED? You are NOT cutting that wire, right? Just attaching the black wire from the optional valet button and the red wire from the optional LED to that red wire?

So...the answer is you just tap them into the red wire?

YES!

Thanks to all for the help!

Some more info and a question...

I just got a Clifford 50.7x which uses this antenna. I took the covers off and did some measurements. The red wire supplies 5v. The control center LED is connected to +5 thru a 200 ohm resistor on the circuit board, and draws about 6.5 ma. The pink wire is grounded by the brain to turn on the LED.

The Grey wire is connected thru the button on the control center and a series 5K resistor to +5v. The grey wire goes to 4.17v when the button is depressed. This kind of surprised me -- I would have thought that the grey wire would be grounded when the button is depressed -- not sure why it is designed this way.

Now my question, can I shorten the antenna lead without any detrimental effects to the units range? I've read somewhere that the antenna lead should be fully extended and not be bundled or coiled up, so I'd like to shorten it.

Thanks.. Ed

Sure you can shorten it.  When DEI's antennas had actual coaxial cable, I did it all the time.  Why not!

However, with the design of the receiver being built into the antenna,  I think shortening the cable now is just to make it a cleaner install.

BTW, I've experimented with the straightened out verses bundled... Not in a car, but on a test board, and it yielded no different results.   Now in a car.. if the bundle was in a bad location (near some oscillator), I'm sure it could have some kind of effect.   But poor decision making like that would affect the rest of your install too probably

Thanks a bunch Mark!

I was thinking along the same lines, the receiver is in the antenna and the antenna cable is just a 6 conductor parallel cable, I don't think it's even twisted pair. I would think that the cable is carrying digital signals to the antenna which then creates the broadcast radio signal, so shorter is better.

I feel better getting advice from someones real world experience, thanks again.

Regards.. Ed
