Make It Yourself Using Bicycle Parts
The cable comes into the engine compartment a little close to the intake and exhaust manifolds, so I slipped a length of rubber hosing over it and used a zip tie to hold it away from the heat.
The cable retainer has a large opening on one side that the cable sleeve sits in and a smaller opening on the other side to allow just the cable to come through. I drilled a small hole in the throttle cable bracket (Off the Jeep, of course) and fit the retainer in place. You'll see how it lines up with the connector on the throttle body next.
