First of all on teh stock crx engine there is a fast idle sensor on
the back side of the intake manifold on the drivers side of the engine, teh
zc does not have this sensor and there is no where to put it so what do you
do with the plug from the harness. Also I noticed that the throttle has
another cable coming from the right side of the engine wht is that for do
you just leave it disconnected. Any help would be grealtly appreciated...thanks a ton if you can help....i need this as soon as possible...

 

I left the plug disconnected and covered in tape to avoid corrosion. That was about 4 years ago, and I'm trouble free.

I'm not sure what you mean by the other cable, but it sounds like it was a car with Crusie Control to me. Remove it if you can, or leave it. I may have misunderstood you though.

 

The zc you have orginally had an auto tranny on it that why it has the extra cable, The extra cable is no good to u so just trow it out.
