Hello, new to forum. I have installed a Clifford 50.7x alarm on my 84 El Camino. I have ran across a clifford back up siren with the key for $5.00. I would like to install this, there are 4 wires. Where do these hook to ? The colors are: Red, Black, Yellow, and White. This siren may not be the best thing out there, but for $5 bucks not sure it will hurt. I also want to install a set of Air Horns. I am assuming I need to install a relay to run all these. Can anyone help with relay specs and how to connect this siren to the normal one? Thanks

Hello, new to forum. Trying to figure out how to properly adjust both zones for my dual zone sensor. I have it directly plugged into the brain of my 50.7x. Can anyone help? DEI tech support sucks and is funny about do it yourselfers. Thanks

Relay for air horns to trigger with alarm Pin 30 - Twelve volts fused according to the rating of air horns Pin 85 - Ground when armed wire Pin 86 - The positive lead of the siren (assuming clifford's siren output is positive) Pin 87 - to the positive lead of the siren

The prox adjustment will have to be dictated by you, we cannot help you there, however the adjustments on the sensor go like this, if you look at the sensor with the two adjustment screws facing the bottom left hand corner, the inner screw expands and contracts both zones and the external screw expands and contracts the inner zone only, the one to the top lerf hand corner is the factory adjustment setting!

I made a mistake in my initial post the last line was suppose to be Pin 87 - to the positive lead of the air horns and you ground the negative lead! ------------- COMMIT YOUR WAY TO JEHOVAH AND HE WILL ACT IN YOUR BEHALF.

I'm confused on pin 85 ground when armed. Can this go directly to ground? Clifford siren output is postive I'm sure. so... pin 30 = 12volts constant fused for air horns rating. pin 85 = Ground ? pin 86 = Positive lead of original siren pin 87 = Positive lead of Air horns Air horns negative is grounded. sound right ?

Need help wiring an old Clifford Backup Siren. This is the older type with a key. Wires are: red, black, white, and yellow. Where do they go? I want to add this with a set of air horns to a 50.7x. Any help would be great. Thanks

Not to sure about that, the ones i use are different from that one you have listed, i know the red and black are constant and ground but the other two i'm not so sure, howard might know!

Hi, I have a 506t and a 508d, the 506t has an extra harness it appears. Is it correct I can plug the 506t into the MUX port of my 50.7x, and then use the extra pigtail to connect directly to my 508d? Would it need diodes then on each of the sensors still? Shall I just not use the 506t? I really like the idea of hooking the piezo siren to the horn honk (-) , can you tell me how to wire the relay to be constant vs. pulsed? I'd like to tie in a set of air horns also. Thanks, Wes

With the Prox 508D, you won't need a glass sensor. Once someone approaches your vehicle the warn away chirps will sound. If they break the glass and reach in, the inner zone of the 508D will trigger full alarm anyway. I had a 506T at one time, and while it will work, too many false alarms from outside noises. Especially if windows are vented.
