2010 mazda 3 and omega excalibur al 1830

Using the tech tips for normally closed door triggers I will include the trunk as one of the alarm sensors. On the DEI information it identified the trunk pin. That increases the protection in my car since I carry a lot of test equipment.

Howie you came through. That's all that matters. Thank you again.

That's OK, I just read the alarm instructions from Mazda, they mention IDC connectors (Scotch locks). Never ever use them, solder and slave or solder and scotch 33+ tape. Sorry if this is suck egg time and you're probably well aware of potential disasters, shaking apart, moisture and corrosion, poor continuity etc. but I had to mention it.

And I agree. I solder and heat shrink every wire, then tape it for a harness.

I can't believe a car manufacturer trains its techs to work like that although I've seen that on a dealer fit Fiat alarm (which we of course binned) but I'd expect that from Fiat/Alfa/Lancia oops Chrysler. Here in the UK the Mazda dealerships are in the front corners of Ford Dealerships but at least the UK Mazda techs I've come across seem to know what they're doing.

Ok I've verified the injectors. The colors match what the file said they should. Not only that but I got continuity to each injector so I'm confident that I have the correct "tach" input. On the 4 injectors they were listed to be in Powertrain Control Module towards the front, pin BB, BC, BD, or AZ. Using that information should make it easy to find the Neutral safety. It should be purple(M/T)in color. Not sure what the M/T stands for. Anyway the 2 Powertrain Control Module connectors are the same so if the BC pin is one of the injectors and the rear plug has the neutral safety on pin BC or S that should be easy to find right? I checked the signal and it should be low active(zero) when in neutral or park. The color of the wire in BC is blue not purple. And it does not change when the car is taken out of park. Any suggestions?

M/T = manual transmission. You only need NSS if your vehicle is a manual. You mentioned park, can I assume an auto? If so connect the neutral safety wire to your reverse light feed (goes to 12V+ when you engage reverse with the ignition on). Otherwise if manual find the wire that goes to ground in neutral and loses it's ground when you engage a gear.

Man what would I do without you Howwie You're the best.

Below is a cut from the installation manual. I guess with this vehicle I will tie this to chassis ground. I mean if the car not in park then the normal key is in the ignition. If I tie it to the parking brake then I have to pull the parking brake before exiting the car or I will not be able to remote start. BLACK/ White Wire - Neutral Safety (-) Input REQUIRED. This input is a critical safety circuit which allows remote start operation whenever the gear selector is in park or neutral (automatic transmission), or when the parking brake is applied (manual transmission). Remote start will not operate unless this wire sees chassis ground. CONNECTION (Automatic Transmission): Connect this to the neutral safety switch wire that shows (-) ground when the gear selector is in the park and neutral positions.

The NSS must see a NEG. By connecting it to either parking brake or reverse wire it will see a NEG if vehicle is in park or neutral or the brake is up. Brake down or as soon as the shifter moves to reverse it will see 12V+ and disable the R/S.
