Default MSD Fuel Pump Booster ?
I have an 01 Z06 with a Pro Charger. It also has a MSD fuel pump booster. The problem is the booster is wired to the fuel pump fuse so the pump runs whenever the key is on. It should be wired to the fuel pump relay but I'm not sure how to do this. Thanks for any help.

You don't use a switch that triggers the pump based on boost?

Yes I know. What I am saying is the fuel pump runs all the time the key is in the on position without the car running. I think it should run for a few seconds until the pressure comes up then shut off. Is this not correct? The BAP simply increases voltage to the pump when it sees boost.

Its not wired correct, someone tapped it off a switched hot wire instead of the proper relay.

I believe there is a dedicated fuse for the fuel pump. Find the fuse under the hood and tap the wire to it using something like this:

Yes, I know. I need to know what wire off of the fuel pump relay to connect to.

That is how it is wired now, it needs to be wired to the fuel pump relay. I need to know what wire to connect to.
