Red Face ECU pining KL31 and KL30

Hello ALL,

I have started with the design of a switch mode power supply (SMPS) dc-dc converter for automotive applications. At the output the loads connected to the SMPS IC will be the ECU (kL 30 and KL31 ) pos and neg of the ECU unit. I am having few questions regarding connections from pin KL31 back to the SMPS power supply IC. KL31 pin which is neg or GND, should it be connected back to the power supply somehow for the neg currents .
