Quick Jake brake question

Recommended Posts

Long story short, my truck didn't have a jake brake and I'm adding one. Turned the Jake on in the computer and added the switch to the dash and apparently there is more than one switch and I got the wrong one because I had to move some wires in the plug to different pins on the switch. Everything is working now. One head on low both heads on high. My question is, on low should it be the back head or the front head or does it even matter. Wasn't sure if you're only going to put pressure on three throws of the crank if it needed to be the ones closest to the clutch or if it even matters. Which way are they from the factory with a brake?

Didn't think about it like that! But you're right, who needs low! LOL but just in case it gets turned on low I didn't want to mess anything up having it Twist on the wrong end of the crankshaft
