I am swapping a universal ignition switch for a Oem fj switch. It is a dash mount 1971 FJ 40. The new switch has 4 blades male connectors in a square configuration and has no markings. Have no idea where the wires on the new switch go. Has anyone had to wire this before or how do I check to find out which one goes where. I have looked at at least 30 diagrams and have searched this sit and google and have not seen what I need. Thank you in advance for any help!!!

It's unclear what you're actually doing. What switch are you trying to install? OE?
No problem, just wanted to help. Let me take a look at mine. Also, @Coolerman is a 71 maestro.
It came with no instructions or markings? Hook a meter to it and test it, hardest part will be figuring the power in poll, once you have that the rest will be easy to figure out which is acc, park light, and lights.
We just went thought this with an OEM switch, and cheap meter that can test connectivity is your best friend, but even a test light will work. hook + to one post and star testing the other posts with key in different positions. Once you have the + on the power in post, you will get power to more then one of the other posts as you turn the key, other wise it will only work with one combination and no others. The universal switch I had did have marking on each post, surprised yours would not. Maybe a good picture of the rear of your universal switch will help us help you.

Thank you @71FFJ40 @mdsims. The problem is not wires and color, it's the new ignition switch. The replacement switch doesn't have the screws in the back. They are blade type. Need to find where the power pole is out of the 4 blades. @cjgoode no instructions and no markings. It is an oe piece but I'm guessing not for my exact vehicle, but this is what they sell now for replacement.

The picture above is the same one you have and the same one I have. See the little markings on the plastic? That will get you going in the right direction along with there wiring schematic
I see markings. Ignition. Start. Accessory.
AM is power in
ST is Starter
16 is IG which is Ignition
ACC is accessories
ST is Starter
16 is IG which is Ignition
ACC is accessories
It's not 16. It's IG, Ignition (blk/yel). ST, starter (blk/wht). Glad you got it worked out.
Or just get some glasses!!!
We put a new EZ wiring harness in mine, still working on it. I have to have my 21 year old son help, even with glasses I cannot see the words on those wires.
