I purchased the full radium hanger, plumbing kit, and two wiring kits. I also have both PDF instructions from Radium for the wire install and the pump install. For the most part the directions are really good, until I get to the wiring piece. Wiring isn't my best area, but generally I have no issues. Additionally, I have searched the forums and the net for the past few days looking for a better understanding of the set up, but the only thing I can find is the diagrams that come in the directions. My biggest question is with the wiring kits, it will utilize resistors and inline fuses to solve the limited 15AMP OEM power limitations. So what then do I do with the original plug that went to the OEM fuel bracket hanger? Obviously, I have to use the fuel level sensor but what gets connected to the top of the hanger from the OEM wires, and what gets connected from the wiring kits? The three OEM relays are still in use, correct? Does that mean I put all of the OEM harness wires just like it shows for a single pump? That's the confusing part. It shows in the install document only connections to a single pump set up, and the wiring kits show how to run the wires for the resisters to the pumps. Call me stupid, for needing a picture of the top of the hanger for a double pump set up but what can I say? Any help would be appreciated.

Just as a side note the two pumps are warlbro 450's.

 

The 2 new pumps will get power from the battery through new relays/fuses. (Each pump gets its own fuse and relay)
The pump relays will be triggered by your ecu (you can trigger both at once or as staged if you have an available ecu output).

 

I did figure it out with a lot of searching. In the end I found a good explanation in Devin Niemela YouTube channel. The large white wire off of the oem harness gets spliced into the configuration. It’s been awhile now, but if anyone is looking for the answer search YouTube for devins stuff and there is a wiring how to. link below.
