Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
can i get the harness number please
should start in a06-
Let me know if you have anymore questions
does the outside harness have the high/low and med/wires wired ?
if not we might have to go directly to the ecm,which is ok as well
if you have the outside harness then locatate c716 and c717
find out what slots they are in and then match them up
what is the engine serial number,we will have to wire to the ecm directly,also there is a possibility that the ecm may have to be programmed to accept the jake wiring inputs.we will know when we test it..
Please give the last 6 of the trucks vin with engine brakes
how about the truck without
i want to see something..
Tell me if this helps,
ok,Let me know you do
we may have to rewire this from scatch,,
is there wires at the 3 contacts at the jake housings at the engine ?
wire it per that cat diagram
Its a perfect guide

I was thinking about this one,per the diagram we need and relay for this to work,and this harness that you have is very basic,Look at that cat diagram again and you will see.
how did it go ??
