NAS D90 Warning Light/Check Circuit

Wondering if anyone can help me troubleshoot an issue. I am trying to sort the last of some problems with the warning lights on my truck. Is anyone familiar with the relay WL1 in this circuit diagram attached and can you confirm whether or not the picture of the yellow relay is the correct one for this application? If not, what is the correct relay for this location behind the dash? This one has a built in resistor and seem is stepping down the voltage to the parking brake and brake fluid switch to 5V. I am not sure that if that is correct as this relay was missing when I bought my truck. Also with the relay installed my check engine light comes on with the brake warning light (i.e. putting on the parking brake). The truck is a 94. Thanks in advance and sorry for the photo rotation.
