87 XJ CPS Wiring

While diagnosing a no start situation I started with CPS. When I located the cps wires, there were no wires to the connector the cps plugs into. I have searched wiring harnesses for loose wires and found none. I assume that it hooks to ECM somehow? What are color of wires cps plugs into? Any thoughts?

No it is not unplugged - no wires from harness side of connector. - I believe I've found the wires - violet/white and black/white that go to ECM - checking this out - Thanx
