Ok, I have been trying this for a week and nothing is working.

I have two switches with positive momentary pulses. I need to create a latching relay that will turn on a light with one and off with the other. The light is just a positive and negative wire that need to be connected and disconnected with the latching.

Here are 5 relays that I bought for this project:

Can someone draw me a diagram that would make this work? It would be great if I can use the positive wire from the light to power the latching relay and switches.

Thanks in advance.

Wire three relays as shown above, then connect the negative lead of the light to the "latched negative output". Connect the positive lead of the light and the relay to a fused 12V+ source. Connect one switch to "pulse to turn on" and the other switch to "pulse to turn off".

now if instead you had one switch give the positive pulse but the other switch be a normally closed switch that would break the ground of the relay, you could accomplish your task with a single relay ...
is that a possibility or does each switch need to be able to power the lights at any given time?
