QLStar Posted February 15, 2015 Report Share Posted February 15, 2015 I have been on the HDT resource site and am still a little confused. I have a 2007 VNL670, I have reviewed the photos for the MAX brake controller plumbing and am a little confused. I have a gray 3/8 line in the cab near the steering wheel release. I looked to me that is the line that Bill B connected to. Will this line give me the use of the Johnson Bar as well? I would really like to have that feature if possible. Just want to make sure I am putting this in the right line. Thanks for the help. Quentin 2007 Volvo VNL 670, Cummins ISX 450. Auto, APU.

QLStar Posted February 15, 2015 Author Report Share Posted February 15, 2015 Sorry QL - I just saw the post. And the PM - yes it will give you both which is why I went there. I had the MaxBrake, but that place actually gets both the normal front, rear, trailer. It comes into the stop lamp switch, so any of the 3 Thank you Bill. I really appreciate the info. Moving forward on the project. Hope to finish the bed this week. Excited about giving PoTater her maiden voyage. 2007 Volvo VNL 670, Cummins ISX 450. Auto, APU.

Alie&Jim's Carrilite Posted February 15, 2015 Report Share Posted February 15, 2015 Here is a previous conversation I had about this. I Tee'd into the line at the stoplight switch behind the dash cluster and it works great. http://www.rvnetwork.com/index.php?showtopic=114988&hl= Alie & Jim + 8 paws 2017 DRV Memphis BART- 1998 Volvo 610 Lil'ole 6cyl Cummins Link to comment Share on other sites More sharing options...
QLStar Posted February 16, 2015 Author Report Share Posted February 16, 2015 Where are you connecting the red wire from the Hayes Brake Controller.? That is the wire for the brake lights when manually activating the controller. 2007 Volvo VNL 670, Cummins ISX 450. Auto, APU.

Alie&Jim's Carrilite Posted February 16, 2015 Report Share Posted February 16, 2015 The red wire taps into the stop light switch wiring. If you Tee the airline into the stop light switch for the air side, find the wires on the switch and tap into the wire that carries the signal to the brake lights.

Excited about giving PoTater her maiden voyage. Well Bill the gray line only is for the Johnson Bar on my truck. It looks like I am going to have to try another line just not sure which one. We both have the same year of truck only mine is a 670. Not sure where to go from here. I have a red line an orange line, yellow line, and a green line that go to the manifold inside the cab. That are my choices. 2007 Volvo VNL 670, Cummins ISX 450. Auto, APU. "PoTater" 2013 Landmark San Antonio, 41' idahopotater@gmail.com Link to comment Share on other sites More sharing options...
QLStar Posted February 18, 2015 Author Report Share Posted February 18, 2015 Thanks for all the input. All hooked up and every functions as expected. Finished wiring the Jackalopee and connected it to the trailer and everything is working correctly. Installing the deck floor this weekend and the hitch. Almost ready to give it the first run with 5er in tow. Can hardly wait. 2007 Volvo VNL 670, Cummins ISX 450. Auto, APU.

PEIFamily Posted May 6, 2015 Report Share Posted May 6, 2015 What air line did you end up tapping into to make it work if the gray one didn't work for you? I have a 2006 670 Thanks 2006 Volvo 670 singled long 2011 Heartland Sundance 3300CK 2006 Smart passion 2001 F350 DRW CREWCAB Link to comment Share on other sites More sharing options...
