4. I found this at bottom of engine room. No idea what it is. It looks like cap of a bolt. Where was it originally? Is it needed?

Thank you!~

is it clean? hmmm... well... it's kind of trick of camera.. I think...

Could that top pix be a vacuum line to the cruise control vacuum motor?

Does your 100 have air conditioning? That connector in the two next-to-last pix could be the connector to the A/C clutch????

No idea what the bracket or cap are.

Well, I don't have cruise control. When see a picture carefully, there is a "balloon" left side. I think it should go there.. but there is no connection on the "balloon".

Second one .. ye, I think so. it maybe air conditioning something. but as you can see, there are only 'male' connectors. I couldn't find any female connectors which should meet the male connectors.

complecated. isn't it?

If you have A/C, there should be a wire coming off the front of the A/C assembly (the clutch) that would have a connector that would mate up with the one in your pix.

The bracket that is sitting above the distributor belongs on the other side of the valve cover. I believe it is called an after run sensor?

White vac. line for the heater valve?
