Hello. I have recently become the owner of a 1987 Mazda rx7 and I have come across a few....issues that have me a bit perplexed. There are a few, what look to be sensors, scattered across the engine bay and are unplugged to anything. I was hoping one of you kind folks could help identify these. I believe there are 8 in total but I will be unable to take pics of the rest until Monday.






Thank you
