I did look behind the ECU and found the modular wire harness where the relay should attach (4 pin) and instead there was matching modular plugin that had a factory jumper wire from position 2 to 4. The metal bracket "lip" on the kick panel sheet metal that the relay should attach to was notably empty. I did test the wires and there was continuity when the wipers were running, with a brief break in continuity when the wipers were at "rest"... so I am pretty sure that I have the right wires. Unfortunately the relay is not a simple "30/85,86,87" relay, but rather controls the intermittent function of the wipers, so the suggestion of using a circuit breaker unfortunately would not work.
