It really should have been there - there would be a 3 pin connector, 
with two cables running out of it, one to the "bolt on the top" WOT 
switch, and one to the "bolt on the bottom and awkward" idle switch.

It's inherent to CIS-E, since the idle switch tells the system to use 
the ISV to maintain a steady idle.  Previous CIS (which a JT/4kq would 
not have had) did not control idle electronically, it was done via the 
auxiliary air valve and idle adjustment screw on the TB.
