Need help locating engine ground straps – 2009 Ram 1500 4.7L with 2012 engine

[jjts]

Hi guys, I’m trying to track down some electrical issues on my 2009 Ram 1500 4.7L. The truck has a 2012 4.7L engine installed, but it is still using the 2009 engine harness.
Right now I’m trying to physically locate all of the engine/block/head ground straps.
So far I found:
One ground near the oil dipstick area
Two grounds on the lower driver side/front-middle area
On the passenger side rear of the engine, I found two braided ground straps coming from the same area
One of those goes to the body/firewall near the PCM
The other disappears toward the intake/rear of the engine and I can’t see where it attaches
One of the original braided straps was broken and had been repaired with 12/14 AWG wire, which I’m planning to replace with a heavier ground cable
I’m specifically trying to figure out: Where exactly do the factory ground straps attach to the block or cylinder heads on a 2009–2012 4.7L?
If anyone has pictures, diagrams, or can describe the physical location like “behind the passenger head,” “above the starter,” “near the transmission bellhousing,” etc., that would help a lot.
I’m trying to avoid removing the intake manifold unless I absolutely have to.
Thanks in advance.

Yes, avoid the intake, Solid block / head connections are a must.

yeah I'm trying to avoid the intake but thank you for your time and response.

There's a neg (-) stud behind the battery,just build yourself some new ground straps to run from it. 1 to the engine block and 1 to the frame should help. Normal battery cables with the ends already crimped on work good as ground straps.

As far as I know, there are 3 main grounds.

Battery to engine block
Rear of passenger's side head to firewall
Engine block to frame..
The firewall ground point has like 3 cables going to it.

this helps a lot thank you.

Invest in the big 3 upgrade. You'll be miles ahead. I've done both my rams, ended up doing my jeep wrangler, that's a big 7 upgrade. I've used 0 welding cable on thevrams and on the jeep #2 cable. All have really improved my electrical performance
