Airpump Electical

I am trying to figure out the electical for the Airpump. I am going to have to include this in my build as this is a California car and will not pass inspection without it.

I do not know how this is supposed to get wired into the new circuit. I see from the wiring diagram that it is tied to a 25A (hot at all times) to a relay that is tied to the ecm.

So:
Where do I tie the constant hot to from the 944?
How do I set this up to a relay that is controlled by the ecm?

What is the easy way to do this (deleteing the airpump is not an option!)?

Thanks,
Ted

86 need to be to a good ground if the ecm puts out a positive control voltage. More than likely it puts out a negative which would mean that you would hook this to a ignition controlled hot wire, I would recommend about a 5 amp fuse on that.

85 would be hooked to your ecm control wire. Check it for + or -

30 would be hooked up just like the diagram, just use a 25amp fuse. I would get my hot as close to the battery as possible without it being right on the battery terminal. On the terminal gives you to much of a chance of corrosion.

87 would be connected to you air pump motor.

87a would not be used.
