    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    Headlights on buzzer... I don't have one. At least if I do it is not working. Is there supposed to be one on these trucks? (2007 338) If so, I'll be fixing it. If not, I'll be installing one. I run with my headlights on during the day and sometimes forget to shut them off.

    Houston we now have an accurate pressure reading in both systems !!! I have been trying to get n owners manual since I got the truck with no luck so some questions I have are probably addressed in it but... As soon as I can actually get one I'll read it cover to cover! So tell me... how does...

    You should be greeted with the most annoying sound in the world. ---- You obviously have never heard my x-wife whine about.... well almost anything.. However... Your 100% correct. I found a wire going to the buzzer that was loose in the connector. Fixed that and now we have the second most...

    You mean this thing? Assuming it is this and the thing with the 2 wires is the pressure sensor switch does that activate both the light and buzzer or just the buzzer? (Note: remember, the light works, buzzer does not) The wires have been painted over but one looks white and the other is dark...

    TV Off air TV antenna

    Thanks for the response! I saw that one but I really don't like that it goes into the window. That would really get in the way of my dog, she loves to stick her head out the window when we are in town at slow speeds. I'm hoping there is another answer...

    TV Off air TV antenna

    I installed a TV in the sleeper and got and antenna from the truck stop. The antenna I got has 2 elements that are about 18" long and mount in a "V". The "V" rods look like short fiberglass CB antennas. It cost about $30.00 at the truck stop. I mounted it on the passenger side mirror as far out...

    I thought when you said the switch was on the parking brake valve you meant the yellow dash button/valve. I didn't think there was anything behind the dash valve for the low pressure switch to attach to but after I read what you said about the parking brake valve I figured I would look. So...

    Do you have access to the diagrams at home or will that have to wait until next week? I'll pull the dash off tomorrow and look at the back of the parking brake valve and see whats back there. Thanks!

    Hey.. New question: I was just out working on some stuff on the truck and found that my low air pressure light comes on but the buzzer has quit working. I have checked all dash and battery panel fuses and they are good. I found a small buzzer mounted next to the steering column on the left...

    I'm in Florida. As long as your not down in Miami the rest of Florida is still considered part of the US.... LOL. It used to be a Fed X expediter truck, (that is why I came here looking for help/answers). We took the box off, cut off about 6' of rear frame overhang, put on a full size sliding...

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    So (with different size tanks combined in the system) I should not have to worry about any tank to tank overflowing while driving? (Assuming no user installed pump is being used to screw things up). As for a controller, that could be done manually. I could just wait until the main tanks showed...

    Engine RPM - Allison Trans -Rear end gears.. HELP

    Well I do have air brakes. An exhaust brake would be nice to have. I wonder, can I get one from an 08-10 and install it in my system? Would I need any new ECU or TCU programming as a result of adding that? And of course I do not have or want DPF... LOL. So, will a 08-10 TCU work for me...

    Engine RPM - Allison Trans -Rear end gears.. HELP

    I may be able to get my hands on some larger tires for a test run if nothing else. In fact I have been discussing that with a friend locally. He is concerned that if I put only larger tires on the back and leave the small ones on the front (For the duration of a 25 mile or so test run) that the...

    Big Truck I work on Hino trucks. I'll answer any questions I know the answers to.

    I was thinking about putting a ball valve (on/off) in the lines to the new tank. When I'm running low I could shut off the "Aux" tank to prevent that. Was also thinking that if I wanted to really get stupid with it I could install a SMALL fuel pump in the feed line of the aux tank and route a...

    Engine RPM - Allison Trans -Rear end gears.. HELP

    Yeah, the power is already marginal. Yeah the 4.11 "LOOKS" great but... I think if gearing is the only and last resort then something in the high 4's would actually be the right choice but, of course nothing in that range seems to be available! Not to mention that a trans reprogram (with the...

    Engine RPM - Allison Trans -Rear end gears.. HELP

    Yeah....Already thought of that. No 6 speed in 2007 and if I go to a 2008 the engine was equipped with different emissions stuff and that might mess with the trans programming? Is the TCM plug the same? I think I would have to come up with a VIN in order to get the 08 TCM? Would the VIN need to...

    THANK YOU.. (I'll look at the other thread in a moment). Since the factory tanks are simply tee'd together I assume I can simply tee the new tank into the system as well and all 3 tanks will equalize (Eventually) and I only need the single currently installed gauge to read the total...

    Greetings Mr. GreasyTshirt..! (Great name for a wrench turner!) 2 issues for you... 2007 338, auto trans. Issue #1: I want to install another fuel tank. I will locate it on left side behind the factory tank. I am most likely going to get a used tank from a salvage yard. Probably from a KW or...
