Hi Matvey, which product are you installing so we can take a look at the guide and get corrections made or looked at? EVO-ALL, EVO-ONE, Key-Override-ALL, EVO-RIDE or EVO-KEY?
I will assume this is for either EVO-ALL or EVO-ONE. I agree with points 1 and 4.
1. Main harness white wire incorrectly stated to be connected to parking lights +. Instead this wire needs to go to second accessory, otherwise the heater will not work when remote started.
-- Ya that shouldn't be there. Not because the Mazda 3 has a 2nd accessory but because that install guide is not a vehicle specific installation guide. It's a normal guide that indicates which wires should be needed when doing a remote start install. Some of the other vehicles that share that connection do not have a 2nd accessory to power up (that,s why the note is there to see wirecolor.com)
Lock and unlock wires need to be manually hooked up
-- Lock-Unlock is controlled by 1 wire in the vehicle. If the vehicle also has an alarm, then similarly, Lock/Arm-Unlock/Disarm wire would need to be connected. If the vehicle has a factory alarm and the Green/Red wire of the EVO was connected to the Lock-Unlock and not the arm-disarm wire, then the data we send out on that Green/Red wire would never actually lock or unlock the car.
-- You can actually do whatever you want for door locks on this car. Either using the Green/Red wire as indicated or by using the Purple and Purple/White with a resistor.
Horn needs to be hooked up
-- Horn is only needed if using the alarm feature or wanting horn confirmations from an aftermarket remote. Installation guides are based off remote starting. When a feature like this is needed, this is why we have wirecolor.com and the Quick Install Guide that came in the Box. It's actually very common practice when installing alarms that you would need to research wires.
Hood pin needs to be installed and hooked up
-- The module does not cover Hood Status through Can-Bus therefore a connection is required if you want hood protection. A note should be in the guide for this but take a look at the compatibilty chart (first page) in the guide or even on the website, Hood status is not covered through Can-Bus; technically this points installers in the direction that they would need to connect a hood pin.
A separate RF kit needs to be purchased and an antenna needs to be hooked up to the main unit.
-- Ok, so now I am pretty certain you have an EVO-ONE. It's written on the website that an RF-KIT is a Required Technology for that car under the EVO-ONE compatibilities. Please read the features available here : http://fortin.ca/en/vehicles/mazda/3/2010/ All the features also have a tiny description you can read though if you want. Just click the little paragraph icon down has a down arrow.
I am just wondering what's the point of having vehicle-specific installation manuals if they have so many errors in them?
-- The guides for the Mazda 3 2010 are not vehicle specific. There's over 30 different cars in that guide since it's for all the Mazdas of various years and share similar connections.
-- Here's an example of what a vehicle specific guide would look like: http://fortin.ca/download/57351/evo-one_ig_reg_bi_maz-3_pts_2014-2015_v2_a_57351.pdf
-- Lots of info is available on all new vehicle specific vehicle guides.
Keep in mind the EVO-ONE is new from last year. It's a little hard to make vehicle specific guides for a product that came out a few years later then the car did. We did redo a bunch of guides though (over 1000 of them). The Mazda and Hyundai/Kia install guides are the last ones left to revisit and update so that it's more vehicle specific and installer friendly :D
Thanks for the feedback!
