Help on 12v Switched Location for Scavenge Pump

So far I have had lots of people supporting my build and truly appreciate everyone.

I do need some assistance on the best location to pull my 12v switched power from. I will be utilizing Deutsch connectors and high quality automotive wiring and want the cleanest place to pull my 12v switch signal from.

I need the switch because I'm running a relay to my scavenge pump for my big turbo. It is already hooked up and running but I need a permanent cleaner solution on the wiring. Pics/diagrams would be a big help. My car is 45 minutes away on the dyno so I need to be ready to wire when I get to it.

Any help would be greatly appreciated as I'm wiring this up tomorrow night!

Thanks

Sorry! I got nothing. I have 0 clue how much amperage it would draw, but could you use something like the in engine fuse box. Or you could tap one of the positive wires for the radar sensor in the front?

I assume a ground is not too hard to find.

I'm not worried about an amp draw, I'm using a relay and that wire would be hooked directly to the battery. I just need a 12v switch to power my relay which barely draws any amps.

I don't mind tapping wires it's just trying to find one that gets a 12v switch signal. Maybe on the radar sensor but not sure what signal that sensor gets.

Anyone know if the stock wastegate gets a 12v switch signal? I'm not using that anymore and that would be perfect.

Any specific area as far as not having to route as far youd like your 12V to come from ? Engine bay? Cabin? Trunk?

Engine bay would be easiest so I can hide the relay and have easy access to the pump and 12v Hot. I'm particularly interested in the wiring going to the internal wastegate harness since they are free now but I am open to any options because my car is 45 minutes away so I don't have access right now to a multimeter and the car.

check pin 1 on the OBD2 connect. usually 12v switched there. if not there, i have a couple more places that would probably work.

Awesome. I will try that first.

Thanks for the help

I just tried pin 1 on the obd and didn't work. Where else could work?
