    I removed the passenger seat and the back seats to do a travel/camper conversion out of my Prius. I noticed the SRS light is on. Can anybody point me to a "how to" as to turn that light off and to do a bypass in the SRS system for the passenger seat?

    Can I, should I remove the passenger airbags too? Anybody know how to turn off the light that says "airbag off" in the passenger seat?

    I did a research on Google and I searched on the forum for the SRS light. All that I found online was that with 2 ohm resistors, the SRS system can be tricked but nothing conclusive.

    I don't get it Pluggo ....?

    Anybody has a how to with pics for the airbag sensor and the seat sensor? I'm a bit lost at what that guy did for the seat sensor.

    Why bother bypassing the passenger side SRS at all? With no passenger detected in the (missing) seat, the bag won't fire regardless. That is all the light is telling you. And with no passenger there, you don't need it to fire anyway.

    Oh I see Bisco. For sure - tape, shrink wrap, whatever it takes.

    Fuzzy, it's just that the light is bothering me a little bit. If I can deal with it, why not; keeping visual pollution out.

    I kept reading and re-reading and I think it's simple enough: it only takes a resistor (2ohm for Toyota from what I read). I saw this 370Z tutorial, the guy is using the chair's plug (with soldering) and sticks the resistor onto it. I've seen another guy buy some waterproof 2 pin auto connectors (male + female kit) and replacing the airbag connectors entirely (ie replacing the yellow connectors with some third party waterproof black connector) and the dude says they're better quality too so no issues later (you know when the car gets old and that connection might get weak and whatnot and the SRS light comes on randomly).

    So, when I'm done with the resistor, I'll let you guys know how it went.

    Duct or electrical tape over the display is faster, cheaper, and more reliable with vastly lower risk of complications or adverse consequences. Plus it is very easily reversible if such is ever needed.

    The resistor path is the hard way.

    Come back with the MPG difference. I'm about to do that but just the rear seats remove, I commute 100 mi a day and for no reason I'm trying to exceed 63 mpg average. The red wine is kicking in with weird ideas.

    I'll have to do a 250km trip soon with the empty car. Not the best point of reference as it will be in the Canadian harsh winter; so far my mpgs been crazy low (short trips+very cold weather, under 15F/-10C). After that, I'm going to install a wooden platform with walls, bolts, locks, latex foam pad, a canister/jug of water, gear - so I'll add quite a bit of weight.

    I'd be interested in seeing your build. I do some car camping trips and might be interested in some of your ideas. Ran across a guy that made a camper out of a little Geo and removed the front seat to install a full length bed.

    Hey kc5dlo, I'll make a short film/montage and you'll see it for sure. I'll post some footage at least, pics and whatnot, when I'm done with the main construction.

    @Grit, my trip was 150km, not 250. The computer said 4.9L/100km, and I saw it rise by 0.2-0.3 approximately while in traffic in Montreal and at the border QC-NY. Officially, at the pump, I calculate 5.6L / 100km. The road was dry, 0 C, strong gust of wind from the side to the point where it was pushing my car off the lane; I think I have a bad bearing too - hearing some noise - so all these might affect mpg. Also Heat working all the time. On average, the computer would give me at lesat 6 l/ 100km on highway under similar conditions - as far as I can remember. If u want to know more just ask.

    Andrei

    Thanks for the info. 2 days ago, I finally got the chance to figure out and pulled the back bench, the tray on top of spare tire, cover tray on top of that and rear seat headrests to see if I can gain anymore MPGs. Today on the way back on, after driving through 3 inches of water of roughly 50 yards (road flooded w/water) and pulling off to the shoulder for police car to pass by, I was able to yield 67.4 mpgs. I may remove the rear seats entirely if I feel adventurous, good thing I have no kids and not married or else that will never happen haha.
