I'm chipping away at 55 years of wiring butchery on this '69 Shelby and found this resistor mounted inside the engine bay. Someone hacked into the dash harness and ran a couple of pink wires to it. I'm guessing this wasn't original equipment? I'm hoping someone can confirm.
By the way, one of the pink wires is spiced into a red/green wire leading to the ignition switch, the other is spliced into a brown wire that shares the same plug terminal with the factory resistor wire. This car has a tach and it looks like the factory pink resistor wire leads to it.

No that is not factory
+1 not factory. In the uncommon event of the resistor wire failing you can ether replace with replacement resistor wire you got from ford or the after market equivalent . That ballast resistor was the fastest way to fix the problem which no doubt was part of the decision process for some.
Here is one that is designed to patch into the harness. https://www.ebay.com/itm/386769016050?
Thanks a lot guys, that helps explain quite a bit, cheers!
If you replace that wire be sure to respect the length otherwise you would modify the resistance.
