Nathanwhit1 Posted 17 hours ago Share Posted 17 hours ago Afternoon all. Can I wire the Mack engine brake to a push switch on the dash. I guess it’s just a feed to the spade connector on top of the rocker cover ? Then do it threw a relay etc ? It’s the 350 E6 engine.

Geoff Weeks Posted 17 hours ago Share Posted 17 hours ago Real old Jakes had a foot switch to apply, I suppose you could. I would want a throttle and clutch switch, don't want it to come on if the throttle is above idle/no fuel position, and clutch keeps you from stalling out the engine when you step on the clutch for any reason. I have had both switches go bad on the road and bypassed them until I got replacements. Yes it will work, but I wouldn't design the system without them.

Nathanwhit1 Posted 16 hours ago Author Share Posted 16 hours ago Do you have a pic of the switches for the throttle and the clutch pedals by any chance ? Is it just that spade connector on top on rocker cover what powers them ?

Joey Mack Posted 15 hours ago Share Posted 15 hours ago you could put a fuse switch on the shifter for easy access. There would be a lot of switching on and off, but it would work. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76056-engine-brake-wiring/#findComment-584524 Share on other sites More sharing options...

Joey Mack Posted 13 hours ago Share Posted 13 hours ago You can come off the fuse panel with a 15 amp fuse, attached to a 30 amp relay, and connect to the heads. You can even go fancy with a head light switch so you can select one or both engine brake heads...
