Okay boys and girls, I'm looking for the bolt hole that the other end of this ground wire attaches to. I did an engine swap and can't remember where I detached it from.IMG_20200804_184356~2.jpg The bolt holes on the engine, that it can reach, are all too big for the eye ring at the other end of the wire.
Hoping someone here will grab a flashlight and take a look under the hood for me. Driver's side. Way down in there.

On my engine that strap is landed on a double ended bolt holding the intake manifold on.

Just taken these snaps from my engine bay.IMG_20200805_173016760.jpg

As far as I can tell, it goes behind the engine and is attached on the back of the driver's side cylinder head.

Hello Guys, my name is Eddie and I am an ASE certified mechanic and just recently had my '06 Mustang V6 4.0L engine swapped for a '07 and was going trough a terrible hardship that no other mechanic shop realized the problem until I did so myself today. The mechanic left my Firewall cable lose also and my car kept blowing the main starter #30 fuse and the reading on my Instrument Panel kept saying "Check Charging System" so my friend bolted a ground cable with double loop holes from the chassis engine part by the passenger side Top Shock absorber to the "Alternator" an so far no mishaps but I do remember during a debate that another mechanic did mentioned that the Vehicle's Stater Motor "Ground" was grounded for the back of the Starter to the Transmission itself...Hmmm, Makes a lotta sense huh? Yep, I did again and did checked the length of that wire and sure enough it does goes back down there behind the engine by the back of the firewall towards the bottom because I juts recently had the transmission pulled down to fix the Main Bearing Seal and he forgot to bolt that thing back on and left it hanging there and after I had it bolted to the engine i was still getting 'No Crank, No Start Symptoms" and had the #30 fuse burning out so yes, it does goes attached to the transmission.

Yep, when the main grounds are resistive/faulty Electricity will use whatever path it can to get to ground the quickest (read lowest impedance). If that's through a fuse then so be it. Of course the rise in amps will blow those fuses every time. Recommendation: If it's been a few years or the voltage output of your alternator seems low or you get a check engine light it's a good idea to find and clean all of the major grounds. Once corrosion sets up resistance increases and all manner of ill behavior can manifest itself. All too often just cleaning the ground connections once in a while will prevent a host of electrical problems.
