2010 mazda 3 and omega excalibur al 1830

I have begun installation of the Excalibur system and have run into some questions. I have all the wiring diagrams (at least the ones that I feel match the system) but I am at a loss as to being able to identify the plugs on the BCM. There are multiple 24 pin plugs and the pins are difficult to identify. I am testing everything with a DVM but I need some help with the BCM. I have found and verified several wiring errors on the diagrams I have. Any help would greatly be appreciated. Thank you

I have found 3 connectors on the BCM that have 24 Pins. Each is a different color and that makes it easy to identify. On my wiring list I have the plugs labeled as E, F, and so on as well as the color of each. My only issue is that the wire colors do not match up with the list. Trying to find them with a DVM makes it difficult when you have 24 wires to test for each signal. Does anyone have a drawing of the pin lables? (a, b, c, and so on) If I had the pins and how they are arranged in the plug, that would make this a little simpler. Thanks for your time.

Help us, what vehicle???

I've loaded the 2010 Mazda 3 onto the Downloads/Manuals section, also try looking for "ready remote" and "Bulldog Alarms" on the web as cross references.

Thank you Howie II. That was what I was looking for. My bust that I had too tight of search and did not see your manual. Funny thing that Bulldog Alarms and DEI do not match. I will be researching today to see which is correct.

I am taking pictures of the installation and will be putting all together in a manual. I have some drawings I have already completed to be included.

I found a copy of the Mazda OEM installation of the remote start. There is some fantastic information on there including the pin identifications of the PCM module. The copy was poor at best and almost illegible but the document number was in the lower right hand corner. Took a chance and googled 4280159 Rev A and up came the orignal document. That should help some of us with the questions like where is the tach (in place of using the injector wires). Just something else I am including in my manual.

Ready remote and DEI didn't match either and they are the same company! Glad you found a solution.

To the 12Volt and tale gunner, apologies for reading the post and not the title. Senile dementia!
