Does this light come with any RPMchips?

Asked by: Gus 17
Thank you for your question. This does not, as it’s designed for a warning light for our temp sensor and oil pressure switches.

I have an Auto Meter Sport Comp Silver tach with a yellow pro-lite which is wired to the tach and a red pro-lite which has two black wires.  What do I connect these two black wires from the red pro-lite to? Thank you!

does the 3242 pressure switch have 2 terminals. 1 to light 1 to ground

Asked by: kirby o
Thank you for your question. We offer two versions which can be a little confusing. If you have a sensor with two terminals one will go to ground and the other to the light. If you have a sensor with only one terminal the sensor will ground through the threads and the terminal will trigger the light.

Can this be used with a 9601 data acquisition dash as a warning light for excessive RPM's?

Asked by: egraham76
Thank you for the question. The 3240 uses a large incandescent bulb and would require a relay to run it off the 9601 Dash. We'd recommend something like model ST534:

I have the 4484 memory tach and was wondering if I could hook up one of these to the tach

Asked by: Justin g
Thank you so much for contacting us. Unfortunately, I'm showing part number 4484 as being a vacuum gauge: Regardless, this particular light is a warning light and does not have the shift light connector on it. It could certainly be hard wired to a tach that has a shift light output (cutting the existing connector off of the tach). If your tach has a shift light connector on it, you would probably want to use one of these shift lights: LED Version: Standard Version: Hope this helps!
