check first... mind did come with a sender but suppliers may be different.... the length of wire that came with mine was pitifully short.. other than that it was complete
 
sorry to drag this tread up again"lol"

do you get one of these when you buy a gauge or do i have to buy one?

If you get an autometer oil temperature gauge it will come with the sender, as thats what I fitted in those pictures, and I totally agree with the above, you will need a long length of single core wire to go from the gauge to the sender.
 
i got the wire as i have wired the light for my boost gauge. Cheers guys. Some fun for me on the weekend. lol
 
The autometer sender I got was 1/8npt and it fitted straight into the M10 hole on my car, I put a tiny amount of Loctite 577 thread sealant on before I fitted it and its been fine for 2 years.
 
so am i ok to fit this oil temp gauge at moment then do oil pressure im few month. All i do is contact that company and get the right part with the correct thread to allow for the both to be fitted?
