I'm looking for a cheat sheet that has the wire/pin locations, and colors to install a remote starter (Viper 4706V) into a 2018 Mazda 3 Grand Touring (Smart Key).
Thank you in advance to anyone that can assist.

You will need a bypass module and the bypass module manufacturer usually supplies an install diagram.
Here is one from Fortin for use with their EVO-ALL bypass module ( in color, too! ) :

very important warning, diconnect the battery before you unplug ANYTHING. Newer Mazdas are uber sensitive and you could burn the keyless module/starting module up very very easily. Even the bypass module with tell you in very big letter to do the same

33 years as a installer now just a retired old guy. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!
