what are these for? with pics

After going through previous trhreads i think the brown one may be off the rockercover. Im not to sure on the other one that is yellow and from the same part of the loom any help appreciated thanks. Mike

Oil pressure switch?
Mine has 16v loom thats the only yellow one there

Thinking about it ive never had a oil light does it go straight onto the switch? thanks Mike

Just looked at my old 8v loom

I have labelled the yellow wire as:

Oil pressure switch on side of head

Should just push onto the sender

The Brown/White one labelled as rocker cover bolt

Thanks guys thats a great help  :y:
