Nothing in the harness pieces I have for my Sunl appears to have a relay. that isn't to say it didn't have one though. Some not-too-mechanically inclined hands took it apart before i got it.
The relay with my Carter Talon harness is a common single pole single throw automotive type. terminal configuration matches your plug, and the numeric terminal IDs and functions match the relay below.
Link below has a commonly available version. worth a shot for the price.
With it removed from my harness, I get nothing at all at when i turn the key. Pretty sure it's basically the secondary ignition circuit tied into the safety switch. Previously i stated "kill" switch when i meant the two wires on mine that at one point probably went to a brake pedal safety switch. With the relay connected and the safety switch wires disconnected from one another, the relay clicks.
