connecting Jaguar to Sidecar

I searched around quite a bit, but couldn’t find the answer, so…
Forgive a noob for a stupid question.
The Jaguar has a slot labeled “servo pwm”. I see pictures of setups with (apparently) the red/black/white wire plugged into this slot and connected to the sidecar at the other end. The red/black/white wires we got in the KoP does not fit into this slot. What am I missing?

Check out this document on the FIRST web site, it should help solve your problem.
