Help Understanding EVTM
Having a concept blockage, need a bit of help understanding something fuel system related. 2005 E-350 with 5.4 gasser,EVTM Cell 23-2 & 23-11.
From what I'm seeing the fuel pump motor's 12 volt power is provided through the Fuel Pump Driver Module, overload protected only by that device or F1.13 20 amp fuse. Naturally the Inertia Fuel Shutoff switch. From what I gather connection points X & V of S312 directly feed the fuel pump motor.
I ask mostly because I'm about to install a Ravelco anti-theft device and would like to use the +12 VDC wire lead for the Inertia switch, just making sure the fuel pump motor doesn't draw close to the 20 amps that circuit is fused for protection. I'm testing current flow with an Electronic Specialities Max Fuse Buddy tester to determine the steady current flow when engine is running: Max Fuse Buddy
So what say the assembled brain trust here?
TIA

From where does the fuel pump motor receive its 12 VDC?
I "think" I know but looking for confirmation or correct.
TIA!
