I have a 528t pulse timer a air ride switch box that has a negative dump trigger on it. I want to use my negative door lock wire as the trigger to the 528t and then I want to have a negative output to my switch box brain. How do I need to wire it? Basically I need a negative in and a negative out so that when I lock the truck the air dumps out.

You could use the negative lock output to trigger a relay to send the negative trigger to your "dump" Your dump works off of a single pulse, or a latched pulse? Hopefully a single pulse. You can wire your relay like this, just re-name the connections

86 is your lock pulse, 30 is the wire needed from your dump.

What kind of car is this? You need to make sure you isolate the (-) lock signal from the OEM lock button to prevent unexpected dumps at high speeds when your passenger locks the doors!

Otherwise, follow the above diagram and it should work.

it needs a latch singal which is why I have the 528t, I have aftermarket locks on the truck so there is no auto lock feature. How long with that diagram hold? I need it to stay on for 5-8 seconds.
