Question Is intercooler pump always on w/ ign?

I am looking for a ign. switched power source up front and wondered if the IC pump was the ticket? Thanks!

Have you ever thought about walking outside to see for yourself?

Here’s your free one . The computer controls the intercooler pump with a relay. Per my observations, the pump appears to turn on a few seconds, maybe 10, after the engine starts, and remains on until the engine is shut off. The pump is off whenever the engine is off, regardless of the key position.

Thanks Hurricane Larry! Yes I looked at it and noticed the same thing (10 second delay) but wondered if it cycled off of temperature, pressure, or any other variable. I ordered service manuals but they are not here yet. Thanks for the free one
