Not sure what you mean. The ignition switch on these ions is an electronic plastic switch. There is no wiring harness just two wires.

I read somewhere that the switch grease inside becomes hard and causes a non-start issue over time. This one is fairly new, (six months). But I went ahead and dissected it. Found it to be a little dirty with lots of what looks like some clear grease. I cleaned it up and will install it back in tomorrow.

I've got three, two of which are new I bought over a few years. Nothing old except the one that was on it from the recall.

 

Good idea. Need to find that relay if one exist. But locating that diagram will not be easy...

 

Ask the dudes over at Saturnfans.com -- there are some diehards over there with fsms to cars they don't even own.

Clearly you know by know I have never seen an Ion. On the road, yes. The mechanicals? Nyet

I did read something about an internal relay that can get fubar'd.

Let me see if I can dig it out of my browser history....
