It is a 2c-2bc-hyl
172c - wiring diagram. I may be onto something though.....these cars have Electrolock Door restrictors on them and there is an ice cube relay (DUL) that is wired in between the door open limit and LA and we are checking to see if that ice cube is pulling in. This is only wired into the 44 door open relay, not the 42 door open relay. trying to find where they have added the coil for this DUL relay on these prints.
