any wheel sensor guru's?

Are you sure you need all 4 wss circuits ... it may just need 1 vehicle speed input from any speed sensor ... some of the newer vehicles i worked on ... typically ecm gets it from canbus ... buffered from abs module ... which TYPICALLY "1" front wss generates signal .
OR from trans module which gets it from internal sensor ... You need to get an original Chyrsler schematic and locate SPEED SENSOR cir operation and then see if you can adapt to existing modification you are performing .
