Re: Blue Ox Baseplate for Trailhawk

FYI....Just picked up my TH at the Jeep dealership with newly installed Roadmaster base plates installed. Took nearly 5 hours to install them (tech had never done them before) and not exactly a pleasant job according to him. Very nice finished job and the mounts actually stick out a little less compared to the tow hooks. It looks like they are close to two inches lower compared to my Liberty so I can drop back to a two inch riser from the 4 inch. $445 in labor!

Ouch! ~$90/hr is par for car dealer, right? I've paid $120 for RV tech work.

Re: Blue Ox Baseplate for Trailhawk

MartinC, After doing some checking, I think that you are right that the supplemental brake will override the RV blinker. I think that a brake light relay kit will do the trick. Roadmaster has one that when the tail lights from the RV are on then it deactivates the signal from the brake switch thereby preventing the toad supplemental brakes from overriding the blinker. I went ahead and ordered the relay kit but hope to test it before it makes it in.

The Blue Ox Patriot has internal battery so having a independent 12v supply from the Rv would not keep it from working if it came loose from the RV. The other option would be to hook up the 12v power to a toad charger to keep the toad battery from running down. I may hook up a toad charger at some time. I have not decided.

My rig has a Jake brake too. How is that involved with the turn/brake light issue? Isn't the only issue when the toad's supplemental brake system is actuated?

My guess is that most everyone that uses the toad's lights runs with the diode solution.

I have the BrakeBuddy sensitivity set real low. It only triggers on a panic stop. I just want to reduce the stopping distance in an emergency. However, my rig is ~40K lbs with tags (with disc brakes) so it doesn't need much help from the CR-V's brakes during routine stops.

Re: Blue Ox Baseplate for Trailhawk

Duh! I'm sorry, I was thinking back to my last set up with the Invisibrake. That used the brake light signal to start braking and was forever coming on. Of course, with a system using an inertia switch, suitably set, that should not be a problem.

That's very interesting - it might do the job. Please let us know what you think of the kit. I wonder, though, if that could be improved by using a constant 12v from the coach to operate the cut-out relay rather than using the tail light wire. That way, it would work day and night.

I'm not familiar with the Blue Ox Patriot you have and will do some more research. Also, someone on another forum (iRV2.com) has recommended using a toad charger so I will look into that now.

Re: Blue Ox Baseplate for Trailhawk

After having two Liberty's that over time had corrosion light problems for toad pulling I decided to go wireless lights on the new TH. So far the product is working exactly as advertised. I place the two magnatized lights on the roof of the TH (used two 5" circle DiamondShield material to prevent any scratching), plug the four blade transmitter into the coachs 7 lug plug (use adapter to go to four lug) and the strong (90 lb rated) magnetized transmiter sticks to the hitch nicely and sends a signal up to 60' back. Such set up runs from $129 to over $600 and the wrecker industry has been using such units for years. time will tell but so far I like the concept. 4 double A's in each light will last up to 16 hour of constant use and there is a low battery warning light. Just my two cents to not have to cut into the complicated electronics of the Cherokee.

Re: Blue Ox Baseplate for Trailhawk

ragoodsp - What wireless light product did you choose that you are satisfied with and where did you get it? Interested people reading this thread might want to know. ldsoles1066 is testing a brake light relay kit and he's shown us where to locate the diodes and which wires to cut. There's been mention of a toad battery charger. I presume it uses a 12V feed from the towing vehicle and provides a managed charge to the toad's battery. If you find stuff that works, let us know what it is. Thanks!

Re: Blue Ox Baseplate for Trailhawk

With respect to the references to Jake Brakes - do you have a true Jake Brake or are you referring to an Exhaust Brake?

Re: Blue Ox Baseplate for Trailhawk

I selected Blazer Manafacturing and purchased the lights off the web for $129.00. Northern Tool, Tractor Supply, AWDirect and many other outlets carry such lights. Just put in wireless lights in your search box. again, wreckers use these set up all the time to not have to deal with the wires, scractching, etc. I think i would buy the wireless light bar next time to totally eliminate any wires whats so ever. ths.

Blue Ox Baseplate for Trailhawk

I've just read the installation sheet for the Roadmaster brake light relay and found it rather scary. For one thing, it calls for the brake light fuse to be pulled before starting work. There does not seem to be such a fuse on my KL. Then it talks about cutting into a wire at the brake pedal. I can't seem to locate any switch or wires there.
It occurs to me that a simple solution to the problem of the toad brake lights overriding the turn signal would be to instal a normally closed relay ( maybe one for each side ) in the BL circuit near where the diodes are and use a constant 12v feed from the coach to open the relay(s) thereby interrupting the toad's BL feed whilst hooked to the RV. Any thoughts?

Edit: on further thought, if there is an open relay interrupting the toad feed to the BL whilst towing, then there would be no requirement for a diode in that circuit. There would be no circuit to back feed into.

Hey grandriver125! I used the term Jake like one might use the term Kleenex. Are you asking if mine is Jacobs branded because Jacobs makes exhaust brakes too, as well as compression release and bleeder brakes. Here's Freightliner's description for mine:

"Many large diesel trucks are equipped with a compression release engine brake system, commonly referred to as a 'jake brake'– so named for Jacobs Vehicle Systems™, the originator of this type of braking system. The engine brake is a device mounted on top of the diesel engine that temporarily changes the timing of the exhaust valves, momentarily shutting down either three cylinders or all six cylinders, depending on Low or High setting. This turns the power-producing diesel engine into a power-absorbing compressor, which provides effective deceleration of the vehicle."

In my rig, the 400 HP Cummins turbo-charged ISL 8.9L engine is teamed with an Allison 3000 MH 6-speed electronic transmission and engine compression brake. Between the engine brake, the Allison and the cruise control, it's set the cruise and let it roll. Won't allow it to go over 5 above the cruise setting even on the steepest grades. Sweet! Mostly the air brakes are used to stop the rig from a roll at a light or stop sign. The engine brake cuts out at about 5 mph. I'd like to have adaptive cruise
