What might be a good alternative to the 3M zip tie squares?
All of my positive (always hot) wires follow a fairly standard path. What path are you suggesting?
I’m always open to suggestions. I can add/delete/update/modify my DIY at any time if needed.
The "P" clips you show would be one. They would take more effort to mount, screw and nut, threaded plate, etc., but would never come undone. Pre-planning with weld in wire clips would be another. But that really requires planning your wire run pre-paint. Or more hole drilling for the plastic clamp type. Pic attached. Or the slide on metal clip type which can grab a frame edge, body pinch edge, etc. Second pic.
Modern cars have gotten away from mounting battery to starter wire on top of the frame. For reasons I mentioned previously. Mounting to the side of the frame or even inside a protected plastic or metal run would be a better solution. On some of my projects, I have run them inside of the frame tubing, even though it is more labor intensive to attach. A lot of OEM runs are inside the C channel of the frame where it is protected.
I'm the last guy who would tell anyone how to do anything. All I'm offering are suggestions for a better or alternative way. In my career, I my oldest fleet equipment I maintain was built in 1939 and also the newest that 2023 has to offer. After doing this stuff day in and day out, you see why the OEM's changed things the way they did. I'm not saying they always get it right, but they do eventually settle in to a safe standard. You just got to keep in mind they do it all, while trying to maximize profits. I always feel we can do better since we have the time and typically, aren't worried about profits.
There's a reason gas tanks aren't mounted in your lap anymore, ala Model A's.
