On the right side of my 2.7 there are 2 ground straps. Both are coming from somewhere in the fender. One is routed under the cat conv but I can't see where it's attached. My question is where should the other be attached? There is yet another one that is in the same bundle of wires that has the oil pressure switch. That one is attached to the block where I can access the bolt. Can I attached 2 of the straps to the block on the same bolt or do they have to be separated?
The one on the passenger side that goes below the cat attaches to the engine cradle. The second one on that side attaches to the head or block pretty much like the one on the driver's side.
...Can I attached 2 of the straps to the block on the same bolt or do they have to be separated?
Which side and location are you talking about? The second one on the passenger side is grounding the cradle to the fender (electrically part of the main structure of the vehicle, i.e., ground) because the cradle is rubber isolated, so that has to be separate at least on that end. They both attach to the same bolt on the fender. Does that answer your question, or are you asking about doubling up on ones going to the engine? Explain a little more and I can answer better.
Thank you Peva. In the pic there is a bolt shown that is part of the inlet air resonator bracket. I thought maybe that's where it originally was attached. Maybe I can just use that for the strap.
Bad news is - that's not the hole that the factory used.
Good news: I don't see why that wouldn't serve for grounding of the engine.
There is a 2nd bolt attaching that bracket to the engine - the bracket base has a 'C' shape that wraps around underneath that EGR tube - and that 2nd bolt is on the bottom end of 'C' base of the bracket, underneath the EGR tube - that bolt points rearward. That's not the right bolt either. But if you reach your fingers into that cavern just forward of that 2nd bolt, you will find the head of a bolt going into the head (block?). THAT's the bolt that the factory used to attach the ground strap. If your original strap tore loose, then the eye that was on the engine end of the strap should still be under the head of that bolt.
The hidden bolt must be accessible by wrench, because some years ago, I replaced my ground straps, and the new one is attached to the original factory bolt. I'm older now, and if I was to need to do it again, I might be tempted to attach to the bolt you indicated and not look back. You'll loose a couple of thread turns of engagement, but I doubt it would be a problem - but convince yourself of that. Or just re-attach to the original factory bolt.
Another avenue for a motor grounding strap is to get a 3' grounding battery wire and connect it from the A/C compressor bolt (front of motor) and connect it to the negative jumper post.
I found the other connection picture. I used the stud for the lifting bracket. I removed the lifting bracket, slid the ground strap on, and re-installed the lifting bracket and bolt.
Thanks to both of you. As usual you all provide clear answers. I found the bolt hole that the factory used after reading Peva's post. The original strap was intact until I tugged on it a little. Then it tore apart. O'Reilly Auto didn't have the right one in stock so I pick up a Dorman universal strap. Turns out it was about 1.5" too short to use the correct hole so I just attached it to the resonator bracket hole. By any chance does anyone have a pic of how the cam position sensor is attached? Since this car has been in pieces for months, I lost track of some things. Normally I keep everything separate and identified but this stuff got away from me. I know a double end stud was used to hold the sensor and the wiring harness but I cannot get the sensor to seat properly. It keeps hitting the sprocket. I'm wondering if there were washers involved that I can't find.
Peva, you are the best! Thank you! What do you mean "mixing up the crank and cam sensor?"? Meaning putting the crank sensor where the cam sensor should be and vice versa? If so, no because I just purchased the cam sensor. I just cannot find the hardware that was used to attach it so I found an old double end stud that probably came off the throttle body. Chances are the proper stud is a different length or something. Thanks for braving the cold to help me out.

That was just a stab in the dark - couldn't think of anything else. I didn't realize that you were missing the stud, but I now see that that was what you were saying earlier.

Sounds like the sensor is going in to the right depth and not hitting the tone wheel. It bottoms out on the top of the hole and the stud needs to have just the right height to "agree" with that so as either not to allow it to go in far enough, or, in the other direction, bend the tab from trying to push it too far. But I think you've figured that out from the photo.
In your pic is the 2nd nut (the one that is against the sensor mount) a part of the stud or can both nuts showing come off the stud? Is there another nut behind the sensor mount hole that is a part of the stud? That's where I'm getting messed up attaching the sensor. I know I should have gone OEM on the sensor but I didn't. The aftermarket was half the cost (probably half the life too). The only Chrysler dealer is 45 miles from me. Also they said they could not find that stud (06505198AA) anywhere in their system. Maybe I can somehow rig one up.
You know - looking at that, I have to think the stud length is not critical (I actually replaced that sensor a year ago, but I don't recall details of it). It looks like the cylinder head has a boss for the stud, the sensor tab seats flush against the boss - at the same height as the larger part of the sensor. Then the nut that is part of the stud clamps the tab to that boss. Then a wire loom tab goes onto the stud and a nut goes on to clamp the loom tab.
Study it closely and I think you'll find that to be the case.
Got it. Thanks again for all your help. I just checked and got codes 0356 and 1391. I'm guessing these have to do with that sensor. I'm going to do a search on here to see what other people ended up doing.
Im putting a motor in a 99 Chrysler concorde 2.7 I have ground straps left over and cant find where they go I forgot where I took them off from can anyone help please I cant find diagram or any info anywhere
On passenger side is a pair. Both attach just below where the negative jump post is. The other end of one goes to the head. The other one drops down and attaches to the engine cradle near the control arm. On the driver's side, they attach at similar points. If you can't find the attachment points, someone may have to post photos.
There may only be one ground strap on the driver's side. If so, it goes to the head. If there are two straps, then the second one attaches to the engine cradle.
Read post no. 5 on page 1 of this thread for details on where the ground strap bolt on the passenger-side head is located - it's kind of hidden.
I ran with 1 grounding strap (replaced and new) for months without issues.
only added the second one back after I sought peace of mind due to an unrelated electrical issue. since the whole engine is aluminum it should conduct electricity extremely well.
