elec brake controller pigtail?
From : homebrewer
Q: well the output shaft sensor seems to be working according to the scanner. funny thing is that the speedometer jumps around alot under 25 or so mph. on the lift with the truck in gear the speedo doesnt move until after 20-25 mph even though the output shaft sensor reading varies directly with observed shaft movement. im thinking rear wheel sensor. there is only one and it is mounted on top of the rear end pumpkin. iirc the manual for my ram said that you need to use a breakout box and jumper a few pins to communicate with the antilock brake controller. i know that was the case with the 94-97s... i dont know if it carried over to the newer abs systems. in fact now that i think about it a buddys 98 1500 with 4w abs had a problem... he took it to several places and they all told him the same thing dealer only - nothing we can do. we did what we could troubleshooting the wheel sensors all checked out good the brake switch bled out what we could etc. never could determine the problem - so he sold it .

2004 ram 1500; installing an electric brake controller. i got a wiring adapter at u-haul and i found the pigtail under the dash behind the e-brake. my problem is the blue wire is only putting out 2 volts at the pigtail. it show 0 volts at the brake controller and at the 7 pin connecter at the bumber. is 2 volts normal or should it be 12v...any suggestions on a fix depends on what its hooked to. hook up the trailer and them try it. dont forget the trailer has to be grounded to the truck. al .
