Have Truck Repair Questions? Ask an Expert
Hi im Alex, i have never done a conversion and don't usually work on kenworth but all manufactures use pretty much the same setup. As far as the speedo goes it sounds like you are on the right track, i know you will have to hard wire VSS direct to ECM, and also have to change sensor type in ECM to magnetic. As far as the key starting, there should be a start enable relay that would normally receive a signal form the TCM saying it was in neutral. Ignition power should come in to this relay on pin 30 of the relay, you should be able to just jump that to pin 87 and then it should start with the key where are you getting the codes form the ECM? hope this helps
do you need any help with this?
