1999 2000 etech Jake brake question

Ok here it goes. I have seen a lot of questions on here about adding Jake Brakes to trucks but searching the site I can’t find topics about this question.

 

I have my old 1999 etech sitting on the floor of the shop. Just started parting it out selling some stuff on eBay.

 

My buddy has a farm truck 2000 Mack with no Jakes. He wants to put my name on his motor. I am thinking no problem mechanically everything should fit. I have all the stuff he needs.

 

The question is how about control? I assume that all flows through the ECM. I haven’t looked at his truck at all so the question is would the wiring be there for the clutch switch, jake, on/off, etc then just turn on Jake settings in ECM. Or would it be totally different harness then wheat he has.

 

If she were mechanical motor we would wire up some switches and go for it. Damn computers. Lol.

 

Anybody got some knowledge on this?

Thanks Guys!!

Awesome! Thanks for the quick reply!! I will have to take a ride to his place and see what I can find in there. I noticed that in my dash there are hookups labeled for things I don’t have so I though just maybe this would be that way too. I’d rather help my buddy get set up with a Jake than haggle with buyers on eBay.

Got this done the other day. Just like you said everything was in place as far as plug ins on the switches. The dang wiring was run right to the heads!! Super easy. Already turned on in the ECM as well. Total plug and play. Thanks Mack!!
