Johnson pump upgrade wiring
I have searched around for this info, and I know this has been covered - but where is the best place to wire this pump for the intercooler, and should it be ignition on all the time, or controlled by the ECU? (factory wiring) -
If it is preferable to be always on with ignition on, even on a daily driver, where is the best place to tap in?
The car goes to my indy Friday to have this installed, and I want to be specific and clear on what I want done.
Thanks in advance guys!

I got the same Question.
I installed the Johnson CM90 but Stevebez told me we cannot use the OEM power source for this pump, it will not have enough current supply for it.
So should i connect the + to the orange wire in the fusebox and ground it to the stock wire ? Or should i ground it anywhere?
