Mystery wire ID
 

Hey all, finishing up the install of a fresh clutch in an '89 rx7 and i came across a wire with an eyelet on the end that I just cant remember where it goes. Just hoping it looks familiar to some of you who can let me know what it is and where it attaches. Its included in the harness for the starter and trans wires that comes down from the engine compartment on the driver side past the starter. Thanks in advance.

That is a condensor for the oil pressure gauge.
Its stock location is one of the clutch slave cylinder bolts but any ground point will do.

Thanks clokker! I was assuming it was some sort of condenser by the looks of the numbers on it, just wanted to get advice from someone with more RX7 experience. Im so proud of the fact that I dont have any bolts left over, i wanted to make sure i put this back in the correct spot too. Thanks again.
