Sure it'll be on all the time though


Try running it off a relay and attach the trigger to something that comes on with the key...

I noticed the harness rubbing the front drive shaft...due to a broken zip tie. I cut and spliced all three of the wires and it still poped the fuse when i turned the key on. I did get the truck towed to house till pure flow could send me a harness. I even changed the relay. What is the relay used for anyway

The relay controls when the pump turns on.
When it receives a signal from (in my case) the factory pump wire, it then opens a path for the power to come directly from the battery using heavier gauge wire.

So it would work it if it was hooked up to the battery with a toggle switch. Pure flow has got my harness on backorder and its been two weeks now since i ordered it.

I've got an extra harness with me. I could ship it to you.

Ok i got the new harness finally lol. Put it on still no go. It pops the fuses every time i turn the key. So i ran a paper clip where the fuse is and it just smoked the wire so i turned the key off quick. So i tried wiring it straight to the battery....still no go. So put new pump on. Got tired and waited the next day to see if she ran. Still no go on the new pump motor. So to rule out a bed new pump i used the old one that i took off and plugged it in and flipped my toggle switch on and bam it ran. So i took apart the new motor to see if the brand new pump was screwed.....nope just frozen...lol so i let her sit in the house for an hour or so and plugged it in and bam it ran...so whats with these things....can they not handle -20 below or what....if i keep the pump looks like ill be insulating it because this was the provlem the whole time. Wow. This was with using diesel 911 here to people.
