I am just finishing a 4 1/2 month frame off build on my 97 f150 and cannot remember where a certain ground wires connects to. It's a ground strap that is coming off of the rear of the passenger head where the bracket routing the wire harness goes. Its probably around 2.5 to 3 feet long. hopefully someone has this answer because I can't find any info on it anywhere online. thanks

 

Mine was going from the back of the passengers side head to the firewall just behind the alternator fuse. Mine has a little green screw that it attached to. Hope that helps.

 

The only strap in that vicinity goes from the manifold to the firewall.

The heads on my truck have been reworked by someone that didn't know what they was doing so I guess they could have attached it in the wrong place. If I was to attach mine to the intake I would have 8 inches of wire drooping down. It's very long!

 

Yea, that's strange. Not sure why there's a ground from the heads ? I can say that I don't have any attached the heads. In-fact, I just pulled the harness/top of my motor off.



- What a mess . But yea, No wires on the heads at all. The aluminum manifold bolts directly to the heads tho, maybe the factory had some in different locations..?

 

brew your flipping nuts

 

What ? Looks that way don't it - Nah, that's a spare harness (parts) in the pic, -chopped up. I'm just replacing a few connectors on the one I'm using.
