I ended up making my own.
Kind of tricky getting the right length and making the ends for it though.

I found the right size cable at a Canadian Tire store here in Canada, but I'm sure there is a hardware store in the US (I'm assuming).

I can take a picture at the throttle body if you like to see what I've done.

These guys may have one _ I didn't check.

I know mine was frayed and I did find one for my 99, but it was quite expensive and now I can't find it.
Ron would probably know if the 94 and 99 are interchangeable, I think both would have the aluminum upper intake, so maybe the same.
