I thought the switch panel would only control the ecu outputs not add outputs? It only has the can bud harness? Or does it have a harness for more outputs on it?
If your talking about a fueltech switch panel yes they are used to turn on a output , I didn’t show a fueltech one. I showed one of my set ups that has its own relay and fuse box meaning your not using up a output from your ft450
Need to add another set of injector wiring run to the fueltech and a different fuel system if you want to just do a change. Unless you mean like two tunes to switch from and drain the fuel
