hmmm....am i missing something? am i nuts? help me here.

IAAI, did you read the data sheet? thats a DS1E-ML-DC12v.

well....thats a 1 form c relay......it says right on the data sheet, and i quote "energize with reverse polarity to transfer the contacts"

??? thats just what i was saying earlier about single coil latching relays.

You are correct. The relays provided in this thread are spring loaded with no ratchet. The relay diagram provided on the site is spring loaded with a ratchet. The ratchet is what makes the relay work with a single, same polarity pulse. I'm sure you can imagine that working. The relays provided in this thread will work on reverse lock/unlock outputs, like those on DEI systems. In other words, hook the lock/unlock outputs to the coil.

What you should be looking for, based on the diagram on the site, is a ratcheting relay.

Here is a mechanical ratcheting relay.
Here is a SSD(electronic) ratcheting relay but, it will produce the exact same results.

So in essence, mechanically the relay pictured on the site is a ratcheting relay, not latching.

Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?

Moral - Never dismiss the obvious.

i think ive mentioned that several times already on this thread ranger. i know how the relay on that diagram is supposed to work....thats not what im asking about, thats not what my question is, a chimp could see thats what the relay in the diagram is supposed to do.......however im positive that relay doesnt work like that. so........my question is "what is the part number for the pictured relay??" can anybody out there give an answer to that question? i'd really like to have some of those that are the SAME type as that pictured and also operate as described. i cant find it. anyone???

Is there any way i can wire up a series of relays in order to get the same effect as the ratcheting relay i mentioned in my first post? I've tried to come up with how to wire up some relays but i just can't wrap my mind around it. Anyone that is good with utilizing relays then this would be a challenge for you.

I need to take one momentary negative pulse and split it into two momentary negative pulses AND have them only fire alternatively. So when i push the trunk release button and it fires one negative pulse, one time it needs to give me a negative pulse down one wire but not the other and then the next time i push the trunk release button i need it to fire down the oposite wire but not the original one.

You would have to use a great deal of care with that system - if you leave any of the relays latched while the car isn't running it will drain the battery.

Are you dead set on staying with a relay only setup? It may be beneficial to use an electronic solution.
