Peterbilt 387 Cat C15 Engine Jake Brake Problem only one solenoid is working

Hi, I have a Peterbilt 387 with a C15 500HP single turbo.. and the jake brake worked but it was very weak.. then it stopped working period. I took off the valve covers, checked the wiring and put a new tune up kit into the brake. When the engine is started and I press down on the solenoid button, only the middle solenoid works. So I bought two new solenoids but still only the middle works.. I have searched thru connectors, wiring, and just can't find an issue.. When I rev it up and let go, sometimes the brake works, sometime it don't.. its just got a mind of its own although the outer ones still don't work.. Please help guys..

UPDATE: I installed new wiring and it still doesn't change anything.. I traced the wiring and found that the wiring running from the brakes to the ECM is fine, now there is three wires that run from the brakes (reddish-orange, brown, black) and go into the ECM.. when i check the wiring running out of the ECM and go into the plug that goes into the cab wall..its as if the three wires multiplied into ten or more wires..in other words the three wires give off power to wires that don't even belong to jake brake.. and also when the ECM is all connected, and I put a tester that beeps to the end of the jake wire and one end on a ground point, it beeps positive.. in other words my ECM is mixing positive or hot wires with ground..is that possible for the ECM to go bad like that?

 

No, when I press down not the button, it 'does' work.. it doesn't work from the wiring itself.. Although I installed new wiring and it still doesn't change anything.. I traced the wiring and found that the wiring running from the brakes to the ECM is fine, now there is three wires that run from the brakes (reddish-orange, brown, black) and go into the ECM.. when i check the wiring running out of the ECM and go into the plug that goes into the cab wall..its as if the three wires multiplied into ten or more wires.. in other words the three wires get the same current on wires that don't even belong to jake brake.. and also when the ECM is all connected, and I put a tester that beeps to the end of the jake wire and one end on a ground point, it beeps positive.. in other words my ECM is mixing positive or hot wires with ground..is that possible for the ECM to go bad like that?

 

Changed the wiring today and the clutch pedal works as I am getting power to the middle solenoid and also if I throw a wire from the middle to the other solenoids..
