Hey guys I’ve got a couple questions. It’s been a while since I did the ole stm fuel pump rewire with my single intank walbro, now I’m lost on these 2 wires on the hanger, the blue and green wire, I know it’s probably a dumb question, I appreciate any help, I can’t believe this thing didn’t come with any paperwork whatsoever , also do I need a second relay or rewire kit? I understand it’s basically supposed to run 1 pump all the time and have the other kick in under a certain load? I’ll keep searching old write ups but I appreciate any help

This is the only info Ive ever seen for the Full Blown Hanger:

Not the most straight forward directions I guess but its enough to figure it out

So after reading some old threads I found the blue/green wires are for the factory fuel level/low level warning wires which ground to the top hat on the stock hanger, which obviously won’t work on an anodized aluminum hanger, here’s a pic:

My next question/assumption would be a second relay?

I would run a 2nd relay for the 2nd pump Jeremy. I saw someone run a setup that kicks the 2nd pump in via link settings somewhere, but IDK where. If I find the thread, I'll post it up.
