The dealership read me the TSB on hooking up anything to the reverse lights of our Ridgelines. Honda says that the wiring and fuse is not large enough to power anything else. So what are these people with back up cameras and trailers with surge brakes going to do?

I don't remember seeing a tsb here, take a look here...
It's TSB #05162005 dated May 2005

I haven't seen the full text of the TSB, but I assumed it was the TSB to fix the problem with the factory harness not using the back up lights, not that you couldn't use the backup lights to trigger off of.

I haven't seen the full text either. I was just responding to lowriders comment that he hadn't seen a TSB on concerning the reverse light problem in the tow harness.

Both the Honda Back-up camera, and the factory trailer hitch wiring have separate harnesses, so they would not 'feed' off of the back-up light wiring or fuse. And "surge-brakes" as I understand them to be (my personal experience) are activated by "travel" in a telescoping trailer tongue. Electric trailer brakes would be another story, but again, they would be fed via the factory hitch harness, which I believe all Ridgelines are wired with (am I right on that one?).

Don't try to feed trailer reverse lights from the backup lights and don't install aftermarket high wattage reverse lights unless you use a relay.

As I understand it some people tried to splice into the backup lights and feed it though the trailer connector for reverse lights on trailers which was blowing fuses.

The TSB has no effect on the backup camera. As for surge brakes they are mechanical and electric trailer brakes have thier own circuit and are triggered from the brake lights, thus the TSB doesn't affect trailer brakes.

Drum surge brakes need no electrical connection but disc surge brakes do. Because disc brakes work equally well in either direction and backing up, especially up a slope, activates the brakes, a solenoid is required lock out the brakes in reverse. The reverse wire activates the solenoid. Without the lockout, disc brakes can lock the wheels backing up.

Thanks Webwader - I just learned something.

I know Honda made a running change at the factory to fix this but I have no idea when it was made. I do know it required a change to the main wiring harness that ran from the front to back. To fix this, to get power to the reverse pin, would require that whole harness be replaced which I'm not sure is even possible and don't know of it being done for anyone.

For what it's worth I tapped into the reverse light wire to power my doppler radar backup sensor but I have no idea how many watts it consumes. After 9 months it's still working just fine, no blown fuses yet.

There is a difference between your printout of NTHSA "Service Bullitins" and what we have been referring to as Honda Technical Service Bullitins (TSBs). When Honda issues a TSB, you as a Ridgeline owner can walk into a dealership and get the work done for absolutely free at your convenience. As of now, there has only been one "recall" by Honda, which is for the Cable End Clips on the door handle and this is also considered a TSB by Honda (TSB 06-012) that has an added wording advising the owners to get the work done as soon as possible.

TSBs cover lots of things. There is one that describes pre-delivery inspection. There is one that describes troubleshooting the NAV. They are designed to help service techs perform some task more efficiently.

They are not something you can just walk in and have done, although some/most dealers will honor your request if you're under warranty since they can charge it back to Honda.

Consider the tailgate-opening TSBs. If you weren't having the problem yet
went in to a dealer asking to have the work done, they would be within their rights to refuse.

If you use the reverse light feed to trip a relay utilizing power from say the trailer harness than there is virtually no load on the reverse light circuit. You should be safe.

I can be of some help here.

I just got done wiring a backup camera in my ridgeline.
due to what is covered in this post I did NOT wire them to my reverse lights.
when I wired a backup camera into my TSX, I did wire into my reverse lights,
but not on the ridgeline.

so this is what I did:

I bought an aftermarket camera. from an ebay member named edogpro.
It was like $60 shipped to me, and it fits perfectly. I bought a tailgate
handle from an 09 ridgeline in the same paint color I have. it has a spot
built into it for a backup camera, which this aftermarket one fit perfectly into.
(well, there was a touch of sanding first, but just a touch).
anyway, on to the important part.

the camera came with a very long wire for the video. it ended in a yellow
rca plug. I used the instructions from honda that came with the attachment
kit and ran that video wire to the cab. the power wire that came with the
camera was very short, and I extended it to be as long as the video wire
using common 18g wire. I ran both wires into the cab as per the instructions.
the instructions with the attachment kit are superb by the way.

so for the camera, there were 4 wires. I cut the yellow rca plug off and
separated out the two very thin wires. I also stripped down the two wires
for the power. so from the camera there was:
video, video ground, power, power ground.
the attachment kit comes with a sub harness that plugs into the navi unit
and runs as far as behind the back seat inside the cab. so I plugged that
into the navi unit and ran it to where I was supposed to. then I cut the
six pin connector off of the tip of it (the white one). well there are 6 wires
there. red, brown, blue, black (actually just the shielded outer wire), yellow,
and white. I tied the blue wire to the outer shielded wire (black on the other
end of the harness) together, effectively "jumpering" them. I tied the yellow
to the video power and the white to the video ground. the red to the power
and the brown to the power ground.
I used the ETM to determine which wire was which.

so basically what I just said is that I wired the camera directly into the nav
unit. or rather into the subharness for the nav unit, but same thing.
there is no need to tap into the reverse lights to wire a backup camera.

Originally, the Ridgeline, official Honda, trailer jack(female) did not have a wired center pin. Honda advertised the trailer package as being 7 pin but did not provide any electricity to the center pin. The center pin is for getting voltage & amperage from the backup lights. Newer surge brake systems require connection here so the trailer brakes won't activate when going in reverse. A trailer's typical brake lockout solenoid uses less than one amp of current and the reverse lights use about one amp per bulb so the total draw, including the reverse solenoid is less than 3 amps. The fuse, on the reverse lamp circuit is much larger than 3 amps so there should be no problem.

Honda provided the proper wiring jack and harness, through a TSB at a later date.

I know this is an old post but it got me to thinking if the ckt that powers the reverse lights can in fact handle the additional current draw of installing an aftermarket backup camera system? If not, would installing LED lamps allow it or would a relay still be necessary?

Hey man, just wandering if you're still around this forum and willing to lend some points of advice? I just installed a 3rd party camera, which gets its power from the backup lights and transmits the video signal, as verified with a portable TV. However, I've been unable to get anything displayed on the stock screen, even though I followed the directions and connected the video signal to pins 1 and 2 and jumpered 3 & 4 together. I get nothing. What the heck am I doing wrong you think?

I'm all set. All done. It finally works. The reason why it took me two weeks instead of a few hours is because the OP never mentioned the fact that he was using a 6-pin connector in a 7-pin hole, skipping one pin altogether. The pictures show it, sure enough, but I didn't see that, I only followed text, which didn't mention this. So I did the rest of it two weeks ago, but that piece of the puzzle had me scratching my head for two weeks. Finally done, thanks to schwejo, who pointed this out to me and made me see the light.
