2006 Mazda 3, remote start

Nice car to work on.

Here's a general outline:

Panel under steering comes off by removing screw behind hood lever. Start by pulling the top first.....careful bottom right has a hinge like hook, don't break it.

Three screws to remove shroud around steering to access ignition wires and immobilizer.

Clutch bypass in drivers kick - one of three gray/black - requires ground during crank. Stay away from clutch switch because firstly it isn't easy access and secondly it is very fragile - can break easily.

Door pins are rest-at-ground type for 4 and 5 door models. They are found at BCM/fusebox under glovebox in a brown plug. Need to create a pull-up circuit using 8 diodes and four resistors.

E-brake is easy access.

The toughest part is trying to get a tach wire under the hood. One method is going through the large grommett behind the glovebox. Maybe others have insight as to better way for tach.

Big Dog is right very easy car for a R/S.

I put one in mine in about an hour. The car comes apart very easy and goes back togther nice without anything out of place.

For the tach wire, there is a small white plate just to the left of the break pedal in an auto, (where the clutch goes for a stick)

that should be easy to get through, and for a stick I would use the large grommett Big Dog noted behind the glovebox.

Have fun.
