Hmm, well, not sure how I missed this post, but didn't find it in search until today. (weird.)

I was thinking about adding a circuit to the rear wiper as well... but on my 16 hour long drive down to New orleans last week, the entire time it rained, from moderate to hellaceous downpour... so i had some time to think as i dodged soccer moms driving in the thick rain while still talking on their cellphones...

If the front wiper delay could be tied to the rear wiper, that would work great for me. Don't have a wiring guide, but would it be as simple as running a relay off the front wiper wiring and interrupting a rear wiper wire?

I watched my driving in the rain, and ya know, the rear on my X gets about as nasty as the windshield does at the same time.. so tying the front to back makes sense to me.

Not knowing the wiring on the 02's... what do ya think?

(PS - I'm a technogeek and love the PIC idea too! But if it's this simple I'd have a hard time going with the controller.
