^Definetly correct
The ground that the ECU supplies to the second relay isn't anywhere near the ECU. It is in fact way up front on the engine! There are several wires originating from the ECU that are grounded on the engine block (probably so there won't be problems with bad engine to bodywork ground straps). On the CRX these wires are attached near the thermostat housing. Other models may differ. If the connection of these wires to ground is loose or corroded, you can get symptoms similar to a bad main relay.
