Fuel pump harness pink wire, 5V? 12V switched?
 

I'm wiring up a oil scavenge pump and it came with a wiring harness and control module to make it run for a bit after the car's off. I've done a search and can't turn up any useful information for this particular problem... It says locate the fuel pump harness and the pink wire...easy enough. But I don't want to go all the way to the back of the car for this. Is this a 5V signal or just a switched 12V? I know pink wires are usually that... Any help is appreciated!

would like some clarification on this too. id like to know which wire exactly i can tap into for the relay so i can wire it in.
