That looks all too familiar, mine broke at the pedal a while back and this week it broke at the ip. Both sides are held together with clamps and zip ties but I ordered a rock auto throttle cable this week to replace it, hope I don't run into the same issues, maybe try to find a nos one on eBay?
I hope yours works out fine too. I remember looking them up and the NOS ones were 2-3x what I paid.
I had to replace the factory one because it must have broken at the IP, it was wrapped around the nub like 4-5 times and by the time I got it off only ONE STRAND was left. Talk about lucky, I drove it home from Texas like that
