Hi All,

My question is regarding silicon insulated wires. They are rated to 200 Deg. C. where TXL is 125 Deg. C. Is there any reason not to use it?

If you can give a link, it would help, but off-hand silicone tends to tear and abraid more, and I suspect the conductor for that application may be solid, or use larger strands, which will be more susceptible to vibration work hardening and fatigue failure?

Ah, thanks. You can try it and see how it works out, but I do have concerns about the possible damage to the silicone, and the quality of the copper can vary a lot with 'cheap' wiring from China - some is right up there with the world's best, but a lot of it is just a mix of different copper alloys and other impurities.

Gord has already essentially said the same, but to reiterate it, when you order from Temu or similar, keep in mind you don't really know what you're getting. It might be acceptable, it might not. They can call it copper, but that doesn't mean it's actually copper. It could be some copper mixed with trash metal from old soda cans. Quality control standards vary from acceptable to almost non existent, so you might get something usable mixed with something unusable.

Given the labor investment in wiring, I really suggest sticking with quality wiring, pins, connectors. A harness fault can cause damage to other components, take a vehicle out of service, and then you have to re-do the work again.
