AFACE

Sorry for the late response holidays suck sometimes. It is the vmac, has a new clutch switch, and not sure how aggressive the wash was. Jake worked for a split second and wont come on now.

Have a truck with the 427 that got pressure washed and the jake quit working. Have signal coming from the vecu but nothing else. Can anyone tell me where the engine brake disable relay is located. I have a good diagram but can't seem to find the component. Any good tips for tracking this one down, I can apply power to jakes and they will work. Has jacobs brake.
