AJRTDDI Posted November 8, 2014 Share Posted November 8, 2014 I'm currently fitting a st170 engine and complete loom into my mk4 escort. Then gonna slowly remove extras like lighting ect. I have the ecu,key,transponder and fuel module unit. I found out some focus have pcm units that pair to the cluster/dials. Will I need this also before the engine will run or is this just unproven facts? Quote Link to comment Share on other sites More sharing options...
JW1982 Posted November 8, 2014 Share Posted November 8, 2014 On the Focus MK1 the instrument cluster is not a part of the PATS system. On the MK1 the PATS system is fully integrated into the PCM. So basically the ST170 engine should run without the instrument cluster connected. On the Focus MK2 Ford changed the PATS system to a more advanced system. On the MK2 the PATS system is integrated into both the instrument cluster and the PCM. Quote Link to comment Share on other sites More sharing options...

AJRTDDI Posted January 6, 2015 Author Share Posted January 6, 2015 Anyone know where 4 wire connect on key transponder pickup. I know pinout of ecu rx/tx. Are other 2 pins live and ground ? Quote Link to comment Share on other sites More sharing options...
JW1982 Posted January 6, 2015 Share Posted January 6, 2015 Pin 1 = Ignition live. Pin 2 = Ground. Pin 3 = PATS signal to PCM pin 19 Pin 4 = PATS signal to PCM pin 53 If you want to also connect the PATS status LED the positive side of the LED should be connected to Pin 42 of the PCM.
