1 more wire on a remote start, white tach wire?

[JOSH P]

Ive run into one small hitch installing the Mazda brand remote start unit on my 2006 Mazda 3, four door, with 2.3L engine.

Looking at the Addendum to the instructions concerning the white Tach
wire from the remote start control unit.
The instructions say to tap a white wire on PIN 2BE (for model year
2006) on the front PCM connector next to the car's battery.
My car is a 2006 model year, but on PIN 2BE my car has a black wire
with a red stripe. I dont know which wire to tap.

There is a white wire in PIN 2BA directly back towards the cars cabin,
but the instructions say to use that position for 2007+ model years. I
do not know how to confirm if my white wire in 2BA is in fact the Tach
wire I need to tap.

Please help me.

if you listen really closely you can here 'noisy crow' looking through his electrical schematics right now..

It was me.
two wires(without high voltage wire) ignition coil
2BE 1st ignition coil White

2007 year
three wires ignition coil with igniter
2BE rear O2 heater Black-Red
2BA 1st igniter gate White

More like you need 2BA.

Looks like, 2006 is transitional year.
Here are wirings for 2005 and 2007

Try to determine what you have. You need “Engine Controls*# ??.pdf” files.
Every version represented by 4 files from *?1.pdf to *?4.pdf .
Your pins in every *4 .pdf
I think the PCM version depends from coil type.

i would test it to be sure. wrong tach wire can fry your rs module. get a voltmeter and set it to read AC voltage, you then rev the car, if the reading goes up and down as you rev then its the right tach wire.

its always good to test 100000x and tap once. hope this helps.
