I know a couple of you guys installed one of these nifty little buttons in your Fs - I am in the midst of putting one in my MX-3, but I need a little help. I know it's not BA related at all, but I'm guessing that most of the electrical stuff is the same!

Anyway, I put the button where my cig lighter once was, got some power connected to it so that the two wires going TO the relay will carry 12V once the button is pressed, but the two wires going FROM the relay and to the ignition barrel apparently carry no power at all. I even replaced the relay provided with a brand new one. There's a click inside both of them whenever the button is pushed. So, they both seem to be working!

Well, the switch going out of the ignition consists of four wires: Black/white, black/blue, red/black and blue. Taking this switch out prevents the car from starting so I obviously need to connect the button to two of those wires!

However, even when turning the key to make the car start, I can't seem to measure any kind of current in any of the four wires, so I made a noobish guess and figured that the button might be alright anyway!

I've heard that the black/white and black/blue wires are the ones I need to connect my button to, but..... no luck thus far.

I need a little help. Where did I f... up?

I'm not sure if the wiring colours are the same on the MX-3 as the 323F BA, but you need to find IG1 and START. The relay needs to bridge those together.

Sounds like you've wired the relay wrong!

You need to go from a 12v feed (i'd run one directly from the battery, fused), into the start button switch, then into pin 86 on the relay. 85 then goes to ground.

You then need to connect pin 87 to either IG1 or START, then pin 30 to the other one of those two.

EDIT:
According to http://www.modifiedlife.com/1992-mazda- ... schematic/

You need the black/blue wire, and the blue wire, the same as the 323F BA I think
