Oil Temp And Pressure Issue On Dash Gauges

[Malc 45]

Looking for help on 205 gti6 conversion, been running all year after converting last winter, however off the road now for some winter modifications (mainly rotrex conversion) but two gauges have never worked, I really want to get these working.

 

Both oil temp and pressure gauges on my dash are at the max when engine is running, when I take the wires off the sensors both gauges drop, unsure if faulty sensors , wired as follows

 

Oil temp gti6 red 411 to 205 white 30a

 

Oil pressure gti6 yellow 414 to 205 grey 30b

 

I have the tee piece fitted with 205 pressure sensor, and the 306 sensor, the oil warning light works fine so I know wired okay,

 

Any advice?
