2011 ecoboost 4x4 wiring schematic??

Hi, wondering if anyone out there have excess to a wiring diagram schematic for a 2011 f150 ecoboost 4x4 as I need to check what powers up the dash on the 2011 ecoboost as well as other wiring, I have one that had damage on the front end with the battery expoding everywhere, the truck did run and drive and the only difference between than and now was that it was water washed under the hood to clean off the battery acid, it did run shortly after it was washed, but after repairs it will not start, as in not turn over the starter and not power up the dash, its as if there isn't any power coming up to the dash as the dash will not light up or power up the gauges when the key is turned on, or it's not recognizing the key. We took it to a ford dealer to scan it and the tech said it would not link to the OBD scanner and said to check for power at the computer and if there was power that it might be the PCM, we have put in a new PCM, no difference, changed out the BCM(fuse box on right kick panel), no difference, we took the under hood wiring out/untaped it all and checked for damage, no damage, still nothing, Hope someone out here can help out, Thanks.

Did you check the fuses at the positive battery cable?

I had a similar experience in a 2010 that we did some install work on. I can't give you details but I can get close. There is several wires leading to a connector that comes down from the steering column and plugs in underneath the dash somewhere. If that connector isn't plugged in, you'll get the same behavior... no dash, no crank. Basically disconnects the ignition switch.

We tapped one of those wires upstream for control power to the battery isolator system. I overlooked it and failed to reconnect, resulting in a panicked call later when the vehicle wouldn't crank.

Hi, we will try and look for the connector your talking about, we didn't actually have the dash out or any wiring in the interior of the truck, but the symptoms appear the same as what you experienced. Are there any modules that would control the dash/key on/ cranking that you know of besides the right hand fusebox/distribution box on the kick panel area. Thanks.
