as the title. im trying to work out if the high power interior loom will fit into a low power and vice versus?
im retro fitting the sat nav as done in the diy section. ive got both cars ready
high power has the sat and and everything is going into the low power.

 

Are you talking about installing a oem nav system out of a 6port into a 4port? And swapping the wiring harness?
I got a 2004 Mazda wiring diagram book I can post up if you think it will help (US version ).

Or are you asking something about electricity?

 

youve got it sorry. yes i am wanting to change the 6 port interior harness and put it into my 4 port.
my 6 port exterior is beaten up and will become a track day car so instead of just selling the sat nav i want to put it into my nice 4 port.
and vice versus will the 4 port harness go into the 6 port.
