Question Ground strap

Anyone have pics for the 5.4 3 valve 2008 slot ground strap. Mines ripped off and I can’t see or feel where it connect on the back of the engine. It’s causing mass misfires across the coil packs and I can’t find where or how it connects, thank you!

xltjasper,

We need someone with a 2008 F150 5.4 to open their hood and tell us where this end of the ground strap from the firewall, next to the PCM, lands on the engine. Picture please.
I have done a lot of research on ground straps and connection points and there is very little information out there.
On the 4.6L (my 2007) the much shorter ground strap from the firewall, next to the PCM, lands on the oil dipstick securing bolt on the back of the engine. I believe the 5.4 is different.
