Help identifying mystery part 2nd gen

Speedo or maybe a throttle cable, 100% not from your Taco though.

 

Here are two mechanical speedometer/tachometer drive cables from my 1962 Triumph TR3 -- one damaged and the other an intact replacement.

I'm guessing there's a generation or two of completely mechanically competent Tacoma owners who have never seen one of these...

 

I'll refer you to my signature ;P

 

Old speedometer cable. Looks like one I pulled off a bicycle once.

 

I used to remove, clean and lubricate Toyota speedo cables.

My own corolla GTS used to HOOOOOOOOOOOOWL in the morning over 30kph if it was winter.

x50 it's a speedo cable.

 

Just put it in the bed of your truck. Drive around for a few weeks. If nothing bad happens , then just toss it.

 

Motorcycle tachometer cable, ends make it appear to be Yamaha. Too short for even a motorcycle speedometer. That's my opinion & it ought to be yours.
