Rewiring the 4banger switch to an OEM alike

Hello
I have bought the Morimoto 4babger pod lights. I would like to replace the Morimoto button with an aftermarket OEM look alike button that I have bought. I'm not an electrician and would like to get your help with understanding which wires goes where.
The Morimoto button have 4 wires: 1xblack, 1xred, 2xblue.
The Aftermarket button have 4 wires as well: 1xred, 1xblack, 1xred&orange , 1xgreen&yellow.
Can someone please help ?

 

When it comes to wiring you need to know what each wire does, just telling people the wire color doesn't really help.

On the OEM style switch usually:
- Black is Ground
- Red1 is 12V out to Relay or light with low current draw
- Red2 is SW illumination 12V in
- Grean is 12V in from a switched source.

You need to found out what each wires on the 4banger switch do and make the connection.

 

I got the info about the after market switch. Here it is.


Im trying to get the info about the morimotos.

 

I dont if it's my bad English or my lack of understanding electricity, but I don't understand the explanation I got from morimoto. Here it is :


Red = Battery +
Black = Ground
2x blue wires = power switch

The blue wires have two ways you can set it up as you can see in the picture below.

If you want to use the Morimoto Switch, it has 2 blue wires already connected inside of it and you don't need to do any additional wiring. Just plug the Morimoto switch into the harness and you're good to go. (One wire is to power on, one wire is to power off)

If you want to use a switch that's already installed in your vehicle, you will connect the bare blue wire in the picture below and wire it to the switch you'd like
to use.


I do have a different wire extension with a blue wire. Where in the OEM switch do I connect it to?

 

The Morimoto diagram did not have any information on the switch wiring itself, the pigtail is what they offer for direct wiring.
They didn't explain the wiring in a useful way...

The Morimoto switch goes to the relay, the black rectanglar thing on the top of your posted diagram.
As this point you are better off using a multimeter to check wire connecting on the relay from the switch.

You can just look up any automotive relay diagram on google.
On the Relay:
Post 87 is the output 12 V to the light pods
Post 30 is the Battery + 12v
Post 85 should be one of the blue wire from the "M" switch, only guesing here you need to confirm that.
Post 86 should the the ground "-"
The other blue wire I think is illuminate when switch is off, may be connection to post 30

All the switch does is close the connection for 86 and 85, when this happen 12v will flow from 30 to 87 and turn on the light.

 

I understand that I need to connect the black in the harnes to the black of the OEM switch because both are ground.
What should I do with the 2 blues and red of the harnes and the 3 reds and the green of the switch?

 

dude, you are looking for simple color-to-color connection, unforunately I can't spoon feed you this time...
You will need to cut the insulation on the round switch and find out what each wire does using a multi-meter or cheap low voltage test pen

- Black: to Black both are ground.
- Red1: need to connect to the "Blue"wire that goes to the relay post 85, you will need to find out which blue wire connects to post 85
This "Blue" wire activate the Morimoto harness relay which then turn on the 4banger pods.
- Green: need to connect the 12V, maybe "Red" on the Morimoto SW, the wire has 12V, most likely the battery 12v + terminal
- Red2: can be connect to 2nd "Blue" wire, this wire is the SW illumination, mostly likely from relay post 30. You may not want to connect this as it could light up the switch at all time and run down the battery.

 

Thanks for explaining what I need to do

 

There isn't much on internet about Morimoto SW to Toyota OEM Switch....
I have Diode Dynamic SS3, there is ton of video and write-up on the wiring.

Keep in mind that Morimoto's harness is self contained and for simplicity they make 12V+ at battery terminal which allow 4bangers to be on even if your truck is not running, you can run the battery down to a point that you can't start the truck.

Red2 is optional on the OEM style switch, this is the backlit for the switch, it may drain the battery if connected to 12v battery terminal direct.
Once you understand what each wire does in the Round switch, you should be able to make the connect and also help any future troubleshooting.

Good luck.

 

Any updates I’m about to attempt the same thing?

 

I ended up installing the original morimoto button

 

10-4 I’m having a local shop do
Mine Wednesday I’ll let you know how it goes.

 

Any update? Im looking to do the same thing.

Thanks!

 

They did a good job they had to change a few things on the harness but it turned out great

 

do you have any pictures or wiring layout you can post?

My wire colors are different (I'm sure they aren't concerned about the colors they just use what they have.)

Thank you for the help!

 

Has anyone done this successfully? (connected a Toyota OEM-like switch to the Morimoto harness). Still haven't been able to find the wiring diagram explain each of the 4 cables that run to the switch. Mine is different from the original post, with 2 blue wires, 1 red, and 1 gray. Any additional help or pictures of your switch wiring would be appreciated.

 

Could you understand the diagram on post #5? If not, stop here and ask a local garage to do this.

The Morimoto push button controls the relay which turn on/off the lights, the switch usually cannot handle the Amp drawn.
On the Relay:
Post 87 is the output 12 V to the light pods
Post 30 is the Battery + 12v
Post 85 should be one of the blue or red wire from the "M" switch.
Post 86 should the the ground "-"
The other blue wire I think is illuminate when switch is off, may be connection to post 30

If you are looking for simple wire color to wire color connection there isn't one that I can found.
Blindly connect wire to another wire without knowing where each wire goes is good way to short thing out and cause damage to your light pods and your truck.

You will need to use a mulitple meter to ohm out each wire from the push button to relay post number, if you can do this then I can help with next step.

 

I do not understand the diagram in post #5. I reached out to Morimoto with the above picture and questions, but still waiting to hear back from them. If they send me a wiring diagram or explanation of each of their wires in the harness, I'll post it here.

Thanks for the tips though and heads up about the potential damage if not wired properly.

If I don't get a clear answer and instructions from Morimoto I guess I'll just have to take to a local electrician or shop.

 

If you can't understand that, really should stop now. No reason to look for another diagram that you cannot comprehend.
You can do a lot of electrical damage to your truck, not covered by warranty.
Morimoto is not going give a rat's a$$ about that diagram I drawn, they are under no obigation to help you wire an aftermark switch, liability and stuff...

The round switch has 4 wires, one goes to post 85 and one goes to post 30, we don't know which is which at this point.
when push the button, 85 and 30 energize the relay, and close post 87 and post 30, so the 12v+ flow to the light pods.
The other 2 wires from the switch are for illumnation, one for head lights on or car ignition on, one for switch is on it probably change color on the switch.
