Bluetooth not powered from ECM?

[KW78]

Hi,

I am slowly but surely moving our enduro cars (miatas) and some customer cars to MS products.

I have a MS1 extra 9495 PNP that I use the bluetooth module to tune, often in pit lane, and/or to run shadowdash. Works great.

I put another bluetooth setup on a MS2 PNP for 99-00 miata, and I find I have to use an external power source, making the pit lane tuning or Shadowdash use not too convenient.

I can wire the car with a 12-5v converter, but I would rather it work like the MS1.

Is this correct? Is there a software output solution or a hardware solution? I don't know what pin on the serial connector the module would need for 5v internal power if I need to alter the hardware.

Thanks in advance for any help!

If it's a DIYpnp there's a jumper you can solder in next to the serial port. If you want (and I recommend it due to blowing one of my serial ports on a serial card) you can put in a pin header and use a jumper to be able to remove power from the serial port when you are using something other than a BT adapter.

Yes, there is a jumper in it to put 5v on Pin9... I'm not sure this is your PNP, but think it is:

Thanks!

I will get it back out of the car and check it out.

Much appreciated,
