bobby121687 Posted March 20, 2007 Report Share Posted March 20, 2007 you do not need to hook up the VSS/speed snse wire for pioneer units Quote Link to post Share on other sites
QQ Posted March 20, 2007 Author Report Share Posted March 20, 2007 bobby121687, but why are others talking about hooking up speed sensor? can you be more specific to why I shouldn't? Quote Link to post Share on other sites
bobby121687 Posted March 20, 2007 Report Share Posted March 20, 2007 from what ive learned you do need speed sensor for other indash units, pioneer doesnt require it. ur speed will still be recognized by gps signal but you mph might be 1mph off... you can hook up yours if you find it easily, it helps for when you lose gps signal, it still knows that you're moving for my car speed sense is by steering wheel, i would need a pulse sensor cuz my car sucks. your car you would need that jus look around... directechs doesnt show your car's VSS.

tillithz Posted March 20, 2007 Report Share Posted March 20, 2007 directechs does show it blue/white Located at the first plug on the ECM, it is a 32 pin gray plug. The ECM plugs can be accessed by pulling up the carpet on the passenger side of the center console. There are 4 plugs total. close also, you dont NEED it to function, but it improves accuracy of the navi about 3 ft. in addition I believe its needed for some vehicle dynamics to work properly. enjoy Quote Link to post Share on other sites
cntrylvr79 Posted March 21, 2007 Report Share Posted March 21, 2007 Yes some of the vehicle dynamics will not work without the vss being connected. Thanks tillithz for beating me to the punch with directechs. Quote Link to post Share on other sites

QQ Posted March 21, 2007 Author Report Share Posted March 21, 2007 thanks all for your input! I found a service manual for my car yesterday. It shows that ECM applies to M/T and for my car, which is a A/T, a PCM unit, which is located underhood, is used instead. The closest location seems to be a blue/white wire between the PCM and the speedometer, which is behind the dash on the driver's side. Anyone has any ideas about this PCM thing? Another thing I am think is that if I can use the cruise control unit, which is close to the gas pedal. do you think some wire there can provide speed pulse? thanks.

cntrylvr79 Posted March 21, 2007 Report Share Posted March 21, 2007 Regardless of the trans, the computer is still in the same place as tillithz listed. As for using a wire at the cc module, try looking for a blue/white wire there. That's common'y honda's speed sense wire at the cc module. Quote Link to post Share on other sites
QQ Posted March 21, 2007 Author Report Share Posted March 21, 2007 tillithz/Batman, are you sure you the info is for V6 model, not a I4 model? Quote Link to post Share on other sites
tillithz Posted March 21, 2007 Report Share Posted March 21, 2007 dont believe its different anyways Quote Link to post Share on other sites
cntrylvr79 Posted March 22, 2007 Report Share Posted March 22, 2007 I4, v6, auto, or stick don't matter it's in the same place. I've done more than a few 7th gen accords. Quote Link to post Share on other sites
