Nytro no power to anything with key on

[Wrenchmaster]

I've got a Nytro with MCX turbo and a rollover valve from 4 stroke solutions installed
I got it as a project, seller said it needed a start relay. I replaced the main start relay with no change. When I turn the key on, nothing, no power to anything. If I jump the red/white wire at the starter relay, it powers up fine just like the key is on and it will crank, but doesn't power down when I turn the key off, have to remove jumper from red/white.
I have power going into the ignition switch on the red wire, all fuses are good, can't find anything wrong with relays, cleaned ground wires, plugged in a known good ignition switch from my parts sled, no change, main power fuse is good. Ground, black wire to ignition switch ohms out with zero resistance to ground, so it's got good ground. Also have ground signal to blue wire on starter relay when ignition switch is in "Crank".
I need to find out if this is the ROV, is it wired into the main power circuit? how can I dx the ROV? power to what wires, normally open/normally closed?

I can't really see how the ignition circuit works from the schematics, there's a solid brown wire going to the ignition and load relay, right now it's about 2V, should this wire carry battery voltage?
If someone knows where the plug is for the kill switch and if it's normally open or normally closed so I can jump it, that'd be great to eliminate that from the list

Roll over valve uses a tether, right?

Yes, it’s got a 4stroke solutions ROV, I don’t have a schematic showing how it’s wired in, but apparently uses the kill switch circuit. I’m going to bypass the ROV, pretty sure that’s the problem
