I am running a Devils Own Stage 1 pressure switch set up. I am not progressive. Is there a way to set up a light that will tell you when the pump is actually pumping? I know how to hook it up to see if the pump is getting power but I want to know when there is pressure going through the lines.

 

My setup shows a light when it sprays but I don't know how its set up sorry

 

how does the meth know when to spray? did the kit come with a wiring diagram?

 

i have devilsown progressive meth kit and my green light comes on when the meth pump is active

 

theres a green wire from the meth controller that taps into my map signal and it sprays when my desire bost is reached

 

I am using a pressure switch that activates the pump when I reach the set psi. The kit is installed and I'm running it but I want to find a way to set up a light that will tell me if the pump is working not just getting power.

I am using a pressure switch style set up, I'm not progressive.

 

Mine is boost referenced to spray over ten lbs

 

Correct, i get what your trying to do. what i was getting at, is what wire is the one that provide power to the pump during that signal. all you need to do is tap that wire, and ground the other side of the light.

 

This. Your switch should have one pressure hose going to it that is getting pressure from the intake manifold or some other vac/boost source. Then you should have two wires: one to the power source and one to the pump. The power wire will be getting power any time the ignition is on so don't tap that wire unless you just want a light show. The wire to the pump will only get power when the desired boost has been reached and that's when it sends power to the pump. Tap that second wire and ground the light somewhere inside the cab. Technically this won't tell you if the pump turns on, it will just tell you when the pressure switch sends power to the pump.

 

^ right, i wouldn't recommend using the washer tank, unless you have a low level indicator. you deff. dont want to run it dry!

 

This isn't what I am trying to do. If the pump itself fails the light will still go on because it is still getting power sent to it. I want to find a way to know there is pressure moving through the lines. I'm thinking I'd have to tap the line with a t and have another pressure switch to trigger the light.

Bingo.

 

Wasn't sure if you meant this or just how to have the light come on when power came on. Honestly I've never seen anyone rig up a pressure switch to turn the light on when meth is flowing. I'm not saying it can't be done just not sure how you would do it. I think the pressure switches that activate the meth kits would be way to sensitive because they kick on at like 10 psi and I think a lot of meth pumps are upward of 200psi which I would think could possibly destroy that switch.

 

i have an interceptor that tells me **** has hit the fan when the pump is not working

 

I didn't even think to use my interceptor. What are you monitoring/have the annunciator set up with.

 

Probably knock retard. If your tune is aggressive with meth and it doesn't kick on, **** is gonna knock.
