Hey guys! Just looked for an hour trying to find a clear pic of where the cas plug connects to. I just installed the motor and can't find where it is in the harness. Any info would be great and pictures appreciated !!! Car is 90 talon tsi awd Thanks
 
On the firewall, underneath the injector resistor pack. There are two 4-pin square connectors here. One for the CAS, one for the TPS/Idle switch combination. Fortunately, the CAS mating connector on the control harness is a female plug and the TPS/Idle control harness connector is a male plug so they really can't get swapped around.

in case you didn't know you need a 90 Cas to go with a 90 harness. if you have a 91 up Cas on this new motor you won't find its plug as it doesn't exist
 
Perfect thanks eclipse90 and pauleyman. I didn't see the third connector on the firewall. It is a 90 cas and the original 90 harness. Thanks !!
