i need help finding the bcm on my 03 bonneville i beilve that is the part anyway. its for my gps system i got installed. he needs to hook up a speed wire to it tells me how fast im going and the time till i get to the places i need to go.
anyway any idea guys?

BCM could be one of two things..

Body Control Module or Blower Control Moodule, to my knowledge on your car..speed isn't brought into either. Maybe have him look to the transmission for the 4000 ppm?

I would think the GPS would tell you how fast you are going....

x2

what GPS are you getting that doesn't already tell you your speed :?

exactly, the gps does not need any input from the car. It calculates by timing signals from different satelites.

If it is the body control module that your were asking about, your car does not have a BCM as such. It is made up of 3 modules; the dash integration module, the instrument panel integration module, and the rear integration module.

I agree with the others that the GPS should be able to detect vehicle speed without any input from the car.

that is it. it cant show my speed cause the wire is not hooked to were it needs to be. and yes he was looking for a body contorl modul.. but if it doesnt have one what should he be looking for? the system is ran off of a gps cd. in a seprate drive its not live

Who (what shop) is doing the install?

Again I say the GPS should give you your speed....

You guys are all wrong.....

The wire off of the headunit the OP is talking about is Speed Pulse.

Correct that the GPS will get aprx speed from the satellite It will not give exact.

The speed pulse give detailed info to the unit and in part help determine eta.

Now the question for OP should be What Head Unit are you installing.

that SPeed Pulse wire should go to VSS.
