I know it's kinda silly, and pointless... but I'm doing one of those push button starts I bought from ebay...just because! Lol.... Anyway, I found a good schematic for 97 and before, but can't seem to find one for 98 and up...Would the ignition wiring colors be the same? I understand that they may have changed some of the wiring in 98...Can someone help me with this info.

Thanks!
Scott.

I'm very confused about this website...don't see anything at all about wiring diagrams...or am I missing something?

Once you get thru the steps listed in the post, you should see a list of "Topics" for your vehicle. The third one down is titled "Diagrams" and is the wiring diagrams. Where are you getting hung up??

I got it...I was just a little confused witch harness was the right one...the above wiring chart is correct.
After the install, the only issue I have, is the rear wiper motor isn't working... I placed the start button in the radio bezel, where the cig lighter was. I removed the bezel to mod it, so the button would fit right. I had to remove the switch harness for the rear washer/wiper...The washer part works as far as pumping the fluid, but no wiper...I located the 15a fuse for it, and it was ok. I was trying to find a relay for it...any ideas where it is, or even if there is one?
 






I added a remote crank capability for compression testing. The same method could be used for a start button. The button would work whether the ignition is on or off. See this link: Remote crank control

I like that...I would add one of those too...If mine wasn't a stick. :(
