That's true, but there is also a cold start valve, controlled by a "thermo time switch" that measures coolant temp and controls how long the valve squirts by supplying ground. They are both at the front of the engine.
According to the wiring list you don't have a cold start relay per se. It's a combination "relay, fuel pump/warm up control". Should be under the dash on the passenger side. Look for the relay with a large violet lead.
