Ground strap

Yep, same as mine

nice, same location as mine!. So my assembled in Venezuela Charger didn't change on that.

I meant that because my firewall got the interlock reset button provisions ( 74 deal ) on a diff location than USA, between ECU and hood hinge, even locally we didn't got the interlock system

Curious, how do you know these braided straps were installed at the factory and not added at some point later? None of my ‘72s had any sign of them, never saw them factory installed at the dealer until later in the seventies. Chrysler was pretty good at documenting electrical circuits pertinent to various originally installed electrical systems, have never seen any reference to these braided straps in the FSM wiring diagrams for the time in question here. The battery terminal to body circuit is well documented. The braded straps referenced here will not handle significant current loads. What I have seen, is plenty of documentation relating to their use to reduce induced radio noise.

Pretty sure in Venezuela what could happen is really somebody could remove it LOL but never added. To much casuality Bob and me got the same attaching point on firewall ;)

Speaking of ground straps; a few years later, as they added more plastic crap and more electronic components to newer vehicles, you may have noticed ground straps everywhere. Under dash, trunk even in places you never saw them before.

Never considered or thought of that. All I know is my car had a braided ground from the block to the firewall but it was broken so I installed the same/like braided strap.

I don't necessarily know if it was done for radio noise reduction from the ignition system, but I would say, mine is original to the car, still has the Chrysler part number, not that is an indication of installed at dealer or factory, but my car also came with capacitor on the coil, one on the instrument cluster, and I think those would do a better job at cutting radio noise than a piece of exposed braded copper wire, that has no shielding would still be able to carry radio noise. I would say the strap on the rear of the engine to the fire wall was braded to provide flexibility and dampening from vibration due to its short length.
