Maybe it's nothing but here's what happening. Towing the 07 Wrangler with our 05 Dolphin on a Workhorse w24. Blinkers work fine with or without toad. Brake lights work fine with or with out toad but,,,,if we are towing and use the turn signals while coming to a stop, the signals work for about 3-4 seconds after applying the brakes and then go straight on, no blink. Let the brake off and the blinkers return to normal operation. Both left and right signals behave the same way. We are using a CoolTechLLC harness on the jeep, factory wiring on the coach. Both work fine independently, both work fine together until you apply brakes, then the blinkers light stays on. Let go of the brake, blinker back to normal. I bought a new blinker module and will see what happens on the way home. Any thoughts or suggestions?

Throw this question to "billarf". He has lots of knowledge about towing Jeep JK's. Here's a current link he follows billarf jeep

Does one of the two vehicles have separate turn signal lights on the rear while the other uses the same bulb for both brake & turn signal? If so, depending on how it is wired, the brake light will "override" the turn signal. Blue Ox sells a kit to prevent that from happening.

If you mean that the turn signal indicator on the dash of the MH goes solid, I would recommend having someone who understands toad wiring look at it as it sounds to me like the MH is getting current feedback that diodes normally prevent from happening. Such feedback to the MH system from the toad can cause electrical damage in some cases.

Yes, it sounds like brakes on the toad are overriding the turn signals, I'm assuming that you have a braking system on the toad. As AFChap said if its stopping the coach signals too, then it is a defective diode or one was not installed at all. If it's just the toad you can also disconnect the battery or pull the fuse per manufactures requirements. Or install the kit that AFChap was writing about.

Let me know what you find out Rick. I haven't towed the 08' Jeep yet with the new harness. Does your Dolphin have seperate brake and turn signal lights? My Itasca does, so I may be in the same boat if that is the case.

There are so many Cool tech harnesses out there right now on 07' - 08' Jeeps, I'm surprised that we haven't heard of this issue before this.....

No, the Dolphin uses 2005 Ford Econoline tailight units. One bulb for both turn and stop. I think the problem has been solved with the replacement of the blinker. I'll know in a few hours when we get under way.

Using a CooltechLLC harness just like almost everyone else towing a JK. I also have the "Big White Fuse" unplugged for towing. Still thinking blinker.
