Gday, Was hoping to get some feedback into the way I wired up the dual battery system & tekonsha brake controller etc into my Prado 150 & Jayco Hawk camer trailer. I did it all a few months back & all seems to work ok, however something seems to be not right with the electric brakes to the camper trailer. When I had a similar setup in my previous vechile (Kluger) the camper trailer brakes would lockup with ease, with the Prado setup I cant get them to lock even though I've replaced brake magnets / machined drums & installed heavier gauged wire. The current seems good & I'm pretty sure it's on the prado side of the wiring.
I've just put together this diagram as to how I've wired it up & would apreciate if anyone can see anything that may attribute to this or have a suggestion ?
