Any OBD power switch options? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

1Cor10:23 · 10-05-2014, 04:32 PM

Wondering if anyone has found some elegant way of incorporating an on/off to OBD ports. Specifically, trying to figure something out for my OFT. I know there's the new low power draw option, which is great but there are times where I won't drive the 86 monday through friday. Just want to be extra sure

You could put switch into wirefor pin 16 before it gets to obd conector and mount it in dash

Buy a obd extension cable and put in an inline switch

some crowd makes a obd connector with built in switch buy one and make your own cable

buying a cheap obd extension and inorporating switch probably cheapest non intrusive way

Did some searching - this looks promising : http://www.fes-auto.com/products_det...p?productid=28

Can anyone confirm if the male connector to OFT is indeed a molex 8? Visual inspection looks close...

As noted in OP, will be common for me to not drive my twin for 5+ days at a time, low draw might be too risky in case of unforeseen absences.

ah gotcha. i missed that part haha.

I thought you were looking for an OBD command to turn off power to the OBD connector.

I thought "Oh that will work, send OBD command to turn off power to the OBD port. Then when you want it back on just send an OBD command to....... wait.."

Why an on/off switched? why you need a "elegant" way for something that is not visible? Just unplugged it. If you can forget to unplugged then you can easily forget to turn off a "on/off switch". Unless you are thinking of an auto-power off obd cable. What if this elegant solution malfuction during ECU writing process.

OFT may offer this in future firmware anyway.

It's not a matter of forgetting. The male/female heads basically have a limited number of uses - lots of people with bent pins, would be particularly bad if you busted the female port on attached to the car. I can only assume same goes for the molex connector on the OFT side.

People are buying $8 extension or "y" splitters to prevent such particularity. In addition you have more options to mount your device.

Not criticizing. Just exploring your idea: cost/pros/cons/alterantives.

*In for results

Update - purchased this from Amazon - going to take ages to ship, likely coming from China.

Nice find! I just ordered one too. If it works as expected, we will buy a load of them and keep them in stock
