Troubleshooting 2000 Toyota Tundra AC 4.7 V8 4WD With Electric Braking Issue


About a year ago I had a local shop wire up an electric brake system to my 2000 Tundra and although it appears to be working, regardless of whether the 7 pin plug is connected to the vehicle or not, any time I hit the brakes, I get a dim glowing effect from both ofthe turn signal indicators at the top of the dash. Not sure why there would be feedbackinch flowing to the turn signal dash lights unelss something they wired up was wrong. Bad ground? I do have LED lights without resistors installed yet, but no surewhy that wold make a difference. The early Tundras had Europeaninch rear tail lights with the amber color and some say thats a wiring nightmare for some installers unfamiliar with Toyota. any help would be appreciated. On another related subject, I notice that when the trailer plug is connected to the receiver in the bumper, that I dont get the hyper flashing from the turn signals like I do when its not plugged in. I attribute that to the fact that my trailelr still has incandescent bulbs and provides enough resistance to satisfy the flasher system. Rather than solder in 4 expensive resistorss iin the system, why couldnt I rig up a dummyinch 7 pin plug to go in the receiving plug where I had a wire going to each turn signal and to ground wit hone resistor in there and leave it in permanently to rid the truck of the hyper flashing? When I would be towing, Id have the plug removed of course, but Im lazy and was lookiing for a work around on this issue. Any thoughts on if this would work? Thanks


Expert Reply:

For your issue, I recommend just using the Brake and Tail Light Trailer Hitch Receiver Cover for 2" Trailer Hitches # CR-007A when not towing a trailer. It sounds like you just need an incandescent bulb to draw power, so I recommend using this cover which has the bulb. If you pull a trailer with LED lights in the future, the adapter # C35FR and # 20142 have the resistors integrated so there is not need to adapt wiring.

The draw on your brake controller shows there may be corrosion because there is a draw on the 5 o'clock pin for your brake controller to see trailer connection. I recommend using some sand paper on the pins and if that doesn't solve it, checking each ground connection.
