75 Dodge Dart Ignition Switch

[JElder]

The ignition switch on my 75 Dodge Dart 360 sport has gone bad. I ordered a new one but the wires on the back of the switch are not in the same places as the one I took off. However, the wires are in the same places as the old switch in the harness. Can anyone tell me if this new switch should work regardless of wire position? Thanks in advance!!

I would "ohm" it out and repin the connector as necessary.

Post the switch photo with a clear shot of the connector/ wire colors and we'll go from there

I have a 75 paper shop manual "somewhere" I'll have to dig it out..........EDIT.........turns out I scanned them, I'll look around here a bit

This should get you started, this is the switch in the 75 shop manual. The diagrams starting in 73 are layed out completely differently than the 72/ earlier ones. I havent found a scan of the connector yet

The big no12 RED (J1-12R) coming in at top is BATTERY power TO the switch. Be CAREFUL!~!! This is UNfused and comes from the ammeter circuit. If you do any smoking/ sparking/ arcing with that you are liable to pop the fuse link, and could even damage the ammeter

The big no12 BLACK (Q2-12BK) is ACCESSORY power going to the fuse panel. It is connected to the RED in "run" and in "ACC"

S2-14Y (No 12 YELLOW) is the start power going to the start relay, and is connected to RED only in "start"

The no 12 DARK BLUE (left off number) 12 DBL is "run" voltage and is connected to RED ONLY in "run" position

The no 14 BROWN (J3-14BR) is the ignition resistor bypass and is connected to RED only in "start"

Other smaller wires would be for "stuff" like the "key light" and the "key in buzzer."

On an aside, it would be nice if guys like you would buy shop manuals for your 75 car, and send a few of us (and me) copies of the data so we can post it.

MyMopar does not have anything later than '73. Here are the aftermarket MyMopar wiring diagrams for '75

Here is the switch connector showing wire colors "in order". this SHOULD match your old switch, and the harness to the panel

From top to bottom the functions are

YELLOW........start
BLACK..........ACCESSORY
DARK BLU.....IGNITION RUN
BROWN.........BALLAST RESISTOR BYPASS
RED...............BATTERY POWER TO SWITCH
ORANGE.........LIGHTING (dash lighting) might be for shifter quadrant
RED................IGNITION BUZZER
(Bottom) RED...ambiguous may be key in light delay circuit

Thanks for taking the time to write up in so much detail. This will help greatly. I've never had a need for wiring diagrams of the car until now. So I have never looked into buying them. I'm surprised they are available. Thanks again for your help.
