Wiring on the 2008 Acura MDX

Here is the all new MDX dashboard.The panel on the side of the dash must be removed before the dash panel under the steering column can be removed.

In order to separate the steering shroud cover, three screws must be removed.

The ignition harness and can-bus wires can be found in the steering wheel shroud area. Constant is white, start is yellow, ignition is pink, accessory is orange, and second ignition is red.

Here the transponder wires are pictured. Using a module will not only allow the transponder bypass, but should also avoid from having to go into the door for door lock/unlock wires.

The parking light wire can be found in the driver’s kick panel. It is gray (+).

The brake wire can be found in a harness above the fuse box. The wire is light green.

Mike used a wire insertion tool to get a path through the firewall for his tach signal.

Any coil can be used for the tach signal. Any wire that is not common with the other coil wires can be used.
