### ⭐⭐⭐⭐⭐ Bogus wiring diagram, but decent product with no major flaws
*by A***E on September 2, 2025*

It's long enough. It's wire is copper (it will not curl in a flame) and it's 18 AWG, which is a bit flimsy IMO but it matches the stated specs, so no fibbing. I find no fault with it, and the price is good. If you trim the leads, you'll want to be prepared to ~3/8" heat-shrink, or tape the loom raw end, as the stuff will quickly unravel if the loom end is not restrained; it's a property of this kind of jacketing. I do find the copper to be . . . brittle? During installation, I broke off two of four wires I'd crimped, at the crimp. It does not seem quite as resilient to bending, but as it stood up to a flame test, it's not CCA. I've chalked it up to my rough handling, but it's not an issue I've encountered doing this sort of thing in the past. The included printed wiring diagram is incorrect, but the wire colors are correct/standard: Green: right stop/turn Yellow: left stop/turn Brown(s): tail/all running lights White: ground The top half of their diagram shows the right side taillight being Yellow, when it should be Brown. That mistake is repeated in one of the pictures in the ad.
