I have a 5ek 3406e that i want to put in my 08 389, ive read that 40 pin ecms wont communicate with the cab multiplex wiring but ive also seen glider kits with 40 pin ecms that work perfect, how do they do this.
Can i just slap a 2ws ecm and engine wiring harness on a 5EK so I can have a 70 pin ecm that will work with 2008 peterbilt cab?
5EK to 2WS

Call kustom truck they can tell you what can or can’t be done.
Roberts450 Thanks this. -
The truck has an SDP cat so I have the right oem cab harness. i was planning on plugging into a 2ws ecm with the factory harness since its a 70 pin plug on both 2ws and SDP ecms
