Oil cooler/temp help

[craig]

I'm about to fit an oil cooler ready for Mr Jackson next year and at the same time am fitting my smiths senders for oil temp/pressure.

1. I know where to fit the pressure sender....but will it matter that I will no longer have oil light on for start up??

2. There is what looks to be a blanking plug above the oil filter, can I use this for the temp sender? I presume I can but not sure what this is for?

3. I am not sure where the oil temp sensor is currently located/or if there is one, does anyone know?

Cheers
Craig
