OBC hook up

[NcTurnL]

Hey guys

I installed my OBC a couple of days ago but I still havent figured out how to hook up the temp sensor for it to show my the temp or the other wire( the one that hooks up to the door gong).

I searched alot but all I find it the color of the connectors?
But how and where (specifically) do I hook up the (Black??) wire to the door gong?

Also, where is the wire for the ambient temp sensor? and what color is it front eh sensor itsself, and what color is the wire to the OBC?

Thanks guys

Also one more question, does the Average MPG go by what the econometer reads or something, beacuse mine says im getting 31.3 mpg?!?! Could it be right, or whats wrong here? lol

you need to make sure you have the correct code plug for your car in the obc( I think your 325i takes a last number 17) and as far as the temp hook up there is a wire plug in block under the drivers side that I believe it hooks to somewhere and the black door gong hooks to the only place available in the door gong in the same area under dash..
