Can anybody help me out?  I have an alarm that has one (-) aux out but it's only momentary b/c it's a 2-way alarm.  I need the output to be changed to 2 outs and one out needs to be a +12v out latched and the other needs to be a (-) latched.

I know to change 1 out to 2 you put the - pulse to 30, +12v to 86, and I used   (-) when armed on 85, then 87 went to one out and 87a went to the other.

Then I needed to make latching relays, one with a + end output and the other with a neg output.  The one with the (-) out is hooked to a DEI 530T window control so I can roll them all the way down and the one with the + out is to turn on the radio.  I have + door triggers so I was going to use that to shut the relays down.

I tried the way on the 12 volt but can't get it to work....can anyone help

You might want to check out our TR-7. It can take 1 channel and split it into two outputs. The outputs can be programmed to be either a pulsed, latched or timed output.. The outputs are negative, but you could use a relay to change one output to a positive.

Other things it can do if anyone cares...
• Low voltage trigger
• CVA-1005 Video Bypass
• Latching outputs
• Double Pulse Output
• Pulse Extender
• Horn Honking Output
• Linear Actuator Controller
• Doorlock Pulse Generator
• Channel Splitter
• Pulses to Constant output
• 3 in 1 timer outputs
• Pulses to latch/unlatch outputs
• Pulses to pulse output
• Pulses to timed output
• Latching outputs #2.

*bonus feature on newer TR-7 shipped FOB*
• Pulsed input to delayed pusled output
• Constant trigger to delayed pused output
• Constant trigger to delayed pulsed outout and when constant turns off, delayed pulsed output

Where could I get the TR-7? I want it for low voltage trigger.

First of all, you should definitely consider using another relay to supply the +12V to pin 86 on the relay you describe above being used to split the output. If you don't, that relay will be energized the whole time your alarm is armed, which naturally will be while the car is not running. Relays can and will drain batteries. To resolve this, cut the +12V wire and send it thru 30 and 87 of a second relay (or first, however you choose to look at it). Tie 86 of THAT relay to +12V, and tie 85 directly to your aux output from your alarm. That way, when you need your output, it'll still be split through the relay that is controlled by your (-) armed-output wire, but that relay won't energize until you actually push the button on the remote.

Now, making a latched relay from a pulsed output depends on the type of pulse. If it's a (-) pulse, you'll tie it to pins 86 and 87 of the latching relay, then tie 30 to ground and 85 to +12V. Piggyback off the wire going to pins 86 and 87, and that'll be the latched (-) output. Now, piggyback again off that wire and use it to reverse the polarity through another relay to get your +12V latch at the same time. That's assuming you need the (+) and (-) latches at the same time, though (it wasn't exactly clear in your post). Otherwise, you'll have to make a latch for each output coming from 87 and 87a of the splitting relay, and whichever one needs the +12V latch will need another relay to reverse the polarity as described above.

Basically, your latching relays can only have the same polarity as the wire triggering them. With a (-) pulse trigger, you have to make a negative latch and then invert it to get a (+) latch.

Let me know if you have a hard time following all this and I'll see if I can put a diagram together.
