hello! i see a lot of people on here have done the upgrade of the OEM speedo to one that hits 320km. is this a straightforward swap, like 1:1, or is there something else that needs to be done to ensure that it works properly. i have the speedo, and the 3-din that match (nismo white face) but wanted to get some input before i actually start this.
some questions:
can i remove the current equipment and just plug in the upgrades and be done with is?
is there a way to bench-test the speedo and 3-din module?
the speedo seems to have a 2-pin plug on the back of the driver's side
the 3-din has IGN and GRN marked
can i just hook those up to a 12v power supply? my fear is frying these things.
Is there a way to set the mileage on the odometer to match my current count? the current one is at about 148k and the new one is at about 28k
thanks in advance!
