Intermittent wiper switch conversion?

[codykrr]

I have the two speed wiper switch right now and you push it for washer fluid.  I am wanting to convert it to the intermittent switch but in the factory place.  Can I just order one or do I need a harness?  Also, will it fit in the current dash bezel?

Thanks

You have to replace the switch and the module. The module plugs in-line with the original harness.
