06 jake brake install

[TowPro]

I am going to start the install tonight and finish tomorrow, but I have 3 questions.



First I am doing this on a 2wd truck which has a different front end then a 4wd truck.



1: Did you pull the inner wheel well liner and do the install through there or did you do it from under the hood?



2: Did you need another person to align the exhaust pipe to get the turbo to line up? (directions show putting brake into exhaust pipe loose, then attach to turbo with someone helping move the exhaust system)



3: Did you pull the DS inner fender well to get to the ECM plug?



Keep in mine I have lots of experence working on cars/trucks, just want to know if I can try to do this from up top (my choice) or should I not waist my time and just pull the wheels and wheel liners. If my Centramatics are here when I get home, might as well pull the liners. (watch them show up Friday afternoon after I am done :-laf )

do not know about the rest of it but you can get to the ecm plug no problem on 4x4 do not know about 2x4 but should not be a problem

On your # 1 question, most people are removing the RF fender liner for easier excess and ease of installation.

Removing the fender well is cake and will save you a lot more time than not doing it. I would not remove the tire though. (Unless your Centramatics arrive! :-laf ) This can be a one man job, but it is easier with a buddy to help align the exhaust and shuttle beers.

I didn't removed the wheel or the inner fender and did all the work w/o help. A 2WD might be kind of close to the ground to get under w/o putting it up on ramps or jack stands or something.

I have one in the box in spare bedroom that needs to be put in also.

We install a lot of exhaust brakes... . we always pull the inner fender and leave the wheel in place... .



We always install the brake to the turbo and get that aligned first... . and wrestle the exhaust to the brake... . we want a good tight seal for the brake to turbo fit. . any leaks and it leads to poor performance... .



We ask each customer to either bring the truck back in 300 miles for us to retighten the clamp or have the customer do it themselves... . remember any leaks can cause lack of performance... .



We always pull the plug to the ECM and insert the connections to make sure they are well seated..... a poor connection here can cause lots of problems, we understand that the pigtails on the wiring loom allows for installation without removal of the connector..... but often our customers are passing through after picking up a new truck and we've found its just a better job to pull the plug and do it that way... . and yes it takes longer.....



Hope this helps...

I got an almost complete kit in a trade and I'm missing the stalk switch. (Cummins P/N 3870838) I'm thinking I might use a different switch but I see in the wiring diagram that there are 3 wires from it (green/yellow to ground, yellow to #39, and red to fan connector) but I'm not sure which ones are connected or open when the switch is on or off. If somebody could take a few minutes to check continuity on the leads and help me figure this out, I'd really appreciate it.

Here is your answer Page 24. complete Wire Diagram.



I installed the exhaust part tonight. 1. 5 hours. Only air tool was to remove the tire. The trick to getting the exhaust pipe back on was to put a pair of vice grips on the exhaust hanger that is welded to the pipe, then use channel locks to pull against the vice grips and the exhaust hanger piece that mounts to the trans. then I got my wife to tighten the 7/16" nut on the exhaust clamp! Tomorrow I will do everything else.



Thanks for the help everybody.

Its all done! Works great. PS: I can't hear my vacuum pump unless I open the hood.



I love the way the ECM works the brake
