OBDII Splitter

OBDII Splitter

Part #:

My wife decided that we just needed to have the Allstate drivewise thingy in our vehicles to save me about 7% every 6 months. Note: She only gets 3%.... lol. So, how was I going to make this work with the OBDII reader that I already had installed in the vehicle. Time to find and buy a splitter. So a quick shopping trip on Amazon I picked up this. OLLGEN 60CM Ultra Slim 2 in 1 OBDII OBD2 Cable 16 Pin Female to Male/Female Extension Connector Cable Splitter. The description is a little wordy. Here is the link.

OLLGEN OBDII splitter
iCar Pro OBDII reader

Description:
1. This OBD2 cable is 2 in 1 female to male/female. It can makes you use more convenient and can reduce the wear and tear on your scan tool's OBD connector
2. High-quality materials give the cable superior flexibility and durability
3. Multiple cables can be daisy-chained together to achieve longer length
4. Compatible diagnostic tools with a 16 pin socket
5. length: 60cm/24inch/2feet
6. Weight: 75g / 2.6oz

I'm pretty certain other splitters will work. I just looked for one with low profile design since this would stick out by my leg. I haven't hit it or even brushed it with the adapter installed, so I'm not as concerned as I was when I first installed it.

Additional Parts:
Zip Tie(s)

Tools Needed:
Diagonal cutter
Ratchet
10mm Socket

 

The cable came coiled inside of a plastic bag with some basic instructions. It has a male/female connector for attachment to the vehicles OBDII port and a single male port on the end of the long flat ribbon cable. With a 2 foot length I can pretty much put this anywhere underneath the dash.
 
Some size comparisons:
My Allstate Drivewise connector alongside me ELM 327 OBDII reader. As you can see the Allstate connector is pretty huge, but I believe it has a wifi adapter built into it.
The adapter is about the same size as the Drivewise connector. The whole assembly stuck out almost 5" from the OBDII port. While the the ELM 327 adapter only stuck out about 3", just a little more than just the Drivewise connector plugged in. I felt comfortable that I wouldn't inadvertently hit it with my leg.
Update: I haven't bumped this at all after a few months and all the connectors are talking to their respected devices.
Update: My ELM 327 worked fine with the older Torque App, but did not work with JSCAN app, so I decided to upgrade/update to iCar Pro code reader. These come in both wireless and bluetooth versions for Android and Apple.
 
Installation:
1. I decided to run the cable up behind the knee panel below the steering wheel. The panel is held in by 4 clips. Pull on the top two sides near the steering column and work you way down. The bottom is hinged in place, so once the 4 clips are release, it just tilts down and pulls off.
2. Remove the two bolts holding the metal panel in place using a 10mm socket. The panel is hooked in place, so you will need to lift it up a little to get it off of the brackets.
3. Plug the cable into the OBDII port and run it up under the dash. Plug your connector, in my case my Drivewise, into the end and zip tie it to something out of the way.
4. Reinstall the panels and plug in your second connector to the OBDII splitter at the base of the dash.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work. While I have spent many years working on mechanical systems, I am not an expert, nor do I pretend to be one. I hope these write ups have been useful to you.
