I am helping my father in law with his new project (2003 Mazda B2300) and need help with the ignition switch wiring. I assume it is the same switch as the Ranger. 50 amp fuse under the hood is OK, lights, chimes, blower motor etc. work. Starter will not work with key. There is no power to Fuse #24 which if I read correct should be hot when the key is turned to start. If I jump 12 volts to the red and blue wire coming out of the switch I do get power to fuse #24. With this jumper in place I can jump across the solenoid and the starter will spin.
I have replace both the ignition switch and the key cylinder. I have 4 hot wires coming into the switch, but do not know if that is the right number. Anybody have the wiring diagram or suggestions.

Thanks.

Welcome to TRS :)

Yes, one yellow wire comes from the 50amp fuse(#11) and splits into 4 yellow wires at the ignition switch

Yes, with ignition switched in START position, its sends 12v out to fuse #24 on a red/blue wire
The key cylinder uses a gear and pulls and pushes the Actuator rod inside the steering column to slide the ignition switch into its 4 positions, ACC, OFF, RUN, START

Can you test the ignition switch manually?
You could have a problem with Actuator Rod not moving ignition switch all the way to START position

That same red/blue wire also sends power to fuse #28 which should MUTE the radio for startup

Tha is for the diagrams. By testing manually are you saying to remove the switch and move the slide rod by hand?

Disconnect battery

Yes, you can use an OHM meter to see if red/blue wire and Yellow wire connection have 0 OHMs, direct connection, when switch is in START

After switch is out, you can hook battery back up and test all 4 Yellow wires for 12v, they are live all the time
And also test if fuse 24 gets 12v in START if possible

Unhook battery to put switch back in

Thanks, I did take the switch back out and manually operate it, at that point I got 12 volts to fuse 24 and to the White/pink at the clutch switch. Had volts on all 4 yellow wires also. Still nothing at battery. Guess next step is to bypass the clutch switch. Any idea on which wire to hook to the white/pink for the bypass. Too darn hot in Virginia to keep messing with it today.

Assuming I get the switch bypassed, I am then back to the key not operating the switch completely, and both are new???
Thanks again for the quick responses.

Diagram here: https://ww2-secure.justanswer.com/uploads/xsvectOR/2011-01-26_193046_1a.gif

Pins/wires, at 5 and 6 are connected together when clutch pedal is down all the way

So in 2003 the white/pink and Pink wires are connected to by-pass clutch switch, pink wire "can be" tan/red wire at the clutch switch in 2003

The Pink wire turns to tan/red wire at the firewall and then runs to starter relay in engine fuse box


You know 2003 Ranger has PATS(passive anti-theft system), which disables starter relay in engine fuse box if wrong key is used to try and start engine
You would get rapid flashing "lock light" in the instrument cluster if this happens
