I want to use the circuit below but I need both pulsed triggers to be + instead of - , how would I go about doing that?

Make the red wire in the diagram go to ground.

Then what do I do with 85 on the center relay? just wire it to + ?

I guess I was afraid that would break the latching function?

If you want a negative output leave it as it is, if you want a positive output, make the black in the diagram positive. This isn't rocket science.

I know, its just been a long time since I have done this stuff! I appreciate your help.

So this is what I want then, right?

Connect the terminals in the diagram that go to the negative pulses to turn on and off to ground (terminal 86 of the first relay and terminal 85 of the third relay). Terminal 85 of the first relay and terminal 86 of the third relay will no longer go to a constant 12V+ source. Instead, terminal 85 of the first relay will be your positive input to turn on and terminal 86 of the third relay will be your positive input to turn off.

When i get a moment, I'll draw one to add to the database.

Er guys were running around in circles here, 12volt and HWW you're both correct but this is what I told the poster to do originally!

Howie, read what the op wrote and your replies again. He was asking for positive input pulses. Making the red wire go to ground is not the solution. See the diagram I linked to in my previous post. https://www.the12volt.com/relays/relaydiagram63.html
