wiring up oil and temp sensors.

as some of you prolly already know, iv put a polo gt engine into my mk1 1.1c and now im trying to wire up the oil and temp sensors.the wires are as follows.. yellow, yellow + red,  black+ blue and a black which went to the old carb.  thr are also two sensors in the head on the rear of engine….any idea which one goes to which?

Just be careful with the black as VW used that for live +ve 12v!!! Yes the rest of the electrical world uses black as -ve or earth just to confuse you.

thanks for the tip!!
