    How-to: coil on plug / coil near plug with hondarulez coil on plug controller part 1

    I'm going to show you the basic tools materials and how I did everything to do my coil near plug conversion. With the external hondarulez coil on plug controller. I'm not going to tell you the pros and cons or why this setup is best that's what Google's is for.
    Warning this conversion is not for everyone. First and foremost the car must be fuel injected and converted to OBD1. Majority of these pictures are mine but some of them are not and most of the information come from Ferenc Mikula (hondarulez creator) Johnny CK Loo ( filmwear software tester) steven simmons ( Simmons tuning and performance) this is going to be a two-part deal. Part 1 will be the old external discontinued hondarulez coil on plug controller. Part two will be the latest technology coil on plug Mini


    (Tools) basic hand tools, Phillips head screwdriver, wire strippers, Barrel crimper tool, soldering iron, heat gun, scissors, terminal depinning tool,


    (Materials) hondarulez coil on plug controller, boomslang fabrication jumper harness or a Ebay jumper harness repinned. approximately 45 ft of 20 gauge mil-spec wire, used for the coil triggers. approximately 20 ft of 16 gauge mil-spec wire use for power and ground wires. You can probably use regular automotive wire to keep cost down. Braided wire loom, cloth wire loom tape, glue shrink tube or regular shrink tube, 4 LS2 GM truck coils, coil bracket to bolt to the head. or you can make your own or Chris (Cygnus X-1) may still have some for sale. Optional 4-pin Molex connector and bullet connectors.

    -fb_img_1544881803685-jpg


    We'll start off with the controller and controller pigtail. The controller has a total of 15 pins pin 6, 12, and 14 will not be used. If your controller did not come with a pre soldered 15 pin connector you'll have to do a little soldering. It's recommended to use some sort of shielded wire for the 15 pin connector and be sure to keep it under 10 inches Long.

    -psx_20181218_192614-jpg

    Once you get that done. Be sure to label all your wires with your wire marker pad. then It will be time to join your controller pigtail with your jumper harness.

    -received_2024861544194805-jpg


    The above picture is the install of the old controller with very high success. Follow the chart for OBD1 column. Wire splice it into your ECU jumper harness. For the box that says A21/A22, choose A21. On the jumper harness Cut it in half and then proceed to connect one wire pin 11 of the controller pigtail towards the ECU and the other pin 10 going towards engine. In the box that says B2/B16 use B16 and that will be pin 15 of the controller. Pins 2 through 5 I use a Molex 4 pin connector. That will be your 4 coil signals. The rest you splice into existing wire. Pin1=A25 Pin7=B11 Pin8=B15 Pin9=A24 Pin13=B10. Always solder your connections.

    Once that's complete it'll be time to gut our distributor of removing the cap rotor igniter and coil if you're using an internal coil distributor.

    -received_606970532998203-jpg

    Once the igniter is removed you're going to splice / join the blue wire and the yellow with green stripe wire together. I cut the flag terminals off and slid it through the rubber grommet and hook them up like so.

    -received_574529859654627-jpeg

    The wire next to this one will now be your power for your coils. The remaining wires left from your igniter go ahead and cut the flag terminals off and slide them through the rubber grommet. Now it will be time to build our engine coil harness. It's best to have your coil bracket bolted up so you know the distance between coils and how longer your wire needs to be.

    We'll start with our 16-gauge wire and make our grounds and power to the coils. Lay one strip a wire across your coils be sure to solder three wires on as these pictures below. You'll make two of these like this.

    -psx_20181215_092822-jpg

    The next one you make will look like this except it will have about 10 to 12 foot of wire coming off of it. It's going to be your sensor ground and it's going to run all the way back to the jumper harness and hook into B2. That gives us a total of three wires and the LS2 coil take a total of 4 which the last wire your ad will be the signal coil triggers.

    -received_2061423563871936-jpeg

    This is a picture looking into the coil.(A)is your ground that you ground to the Head or distributor Bolt. (B) is your signal ground and will run all the way back to the jumper harness splice into B2. (C) is your coil trigger signal for cylinder 1 through 4. (D) is your power to power to coils it'll be one of the wires that come from the two pin plug from your distributor

    -received_1620866901347091-jpeg

    Now be sure to take your multimeter and test all your wires to be sure your connections are 100% if everything looks good now you can wrap it with wire loom tape. Add braided wire loom and Shrink tube your ends. Crimp and solder your LS2 connectors to your wire along with your 4-pin Molex connector. And repeat your testing with your multimeter to be sure everything's good.
    Then add your Billet distributor cap and fire it

    Re: How to coil on plug / coil near plug with hondarulez coil on plug controller part

    I'm only allowed eight pictures per post. This is how your wire should be spliced and soldered into the jumper harness

    -received_2024861674194792-jpg -received_2024861687528124-jpg

    and this is how your harness should end up looking like

    -fb_img_1545205598122-jpg -fb_img_1545205616227-jpg

    And this controller will also work for the B swap guys you'll just build your harness little different and most likely be using K20 coils.
    And if you're using a modified distributor that changes the firing order you will need to redrill the key

    -psx_20181219_144132-jpg

    or swap plug wires around or build your harness a little different. That'll be it for now I'll be sure to keep this updated clean it up as best as possible. Part 2 will be next

    -screenshot_20181218-024314-jpg

    To be continued

    Re: How to coil on plug / coil near plug with hondarulez coil on plug controller part

    All right we're going to go ahead and start part 2. coil on plug mini. it's the latest technology that is available on the market today. The wiring is going to be just a little bit different. We're going to need all the same basic tools and approximately the same amount of wire as above. Except you'll need a female 6 pin micro Molex connector. It will plug into the coil on plug mini for the RPM and 1 through 4 coil signals. First thing you're going to want to do is gut your distributor like above except this time we're (not) going to jump the blue and yellow with green stripe wire. Once you remove the igniter you're going to want to remove all the wires that hooked up to the igniter we're going to need that 2 pin plug connector to build our harness. Start off by making your power and Main ground wire for coils like recently.

    -psx_20181215_092747-jpg -psx_20181215_092822-jpg

    Now we're going to add an extra wire To Rundown next to our power of the coils. The white wire in the picture

    -psx_20181215_092949-jpg

    this white wire will run with the 1 through 4 coil signals all the way back to the ECU. Now with the two pin connector we removed from our distributor that will now go on our white and yellow wire.

    -psx_20181219_150942-jpg

    and add your coil signal wires 1 through 4. Go ahead and add your ring terminal to your main ground that will go to the head or the distributor Bolt. And also add your last ground wire that will run all the way back to the ECU and ground at B2.

    -psx_20181219_151234-jpg

    like before check your connections with your multimeter make sure everything's legit. If everything's good you can go ahead and wrap your wires with wire loom tape.

    -psx_20181219_151025-jpg

    And prepare to crimp and solder your connectors. The white RPM wire and coils signal 1 through 4 will go to the micro Molex 6 pin connector.

    -psx_20181219_174921-jpg

    after you get that right go ahead and add your wire loom and that'll be it for the harness.

    -psx_20181219_151052-jpg

    That means you'll have a total of 5 wires running to your 6 pin micro Molex connector and one wire that runs and get splice into B2 at your jumper harness.

    Excellent work. I did some light editing for readability and...

    Stickied.



    So are you going to mount a trigger wheel or are you using the existing crank sensor within the old distributor? Can't wait to see everything mounted up and working!

    Re: How to coil on plug / coil near plug with hondarulez coil on plug controller part

    Alright our next step will be soldering inn are 12 pin header plate to the board. It's best to remove the ECU board completely from the ECU casing. Desolder the 12 holes and solder in the 12 pin header.

    -psx_20181219_190247-jpg

    we will lay are ecu board in the casing to see where we have to cut our Notch and drill our hole.

    -psx_20181219_183907-jpg

    once we get our Notch cut and hole drilled install are nylon spacer and screws to hold the coil on plug board secure to the casing. Our last step will be soldering the purple wire to A21 are old igniter signal. and the yellow wire to A25 for power.

    -psx_20181219_183833-jpg

    that's about it here's a video from Burton Racing to give a better visual on it. https://youtu.be/fbdDru5nhn0

    That will complete our how to coil on plug coil near plug conversion

    yeah that was my question What distributor? although its obvious to me.

    Any reason you can use the stock one I assume the signals are the same.

    Great write up!

    ill expect the k20 sawp one by New year I would assume.

    Sorry for the late reply. that is a good question. I believe the pre obdo vacuum advance distributor is missing a sensor. if we were able to add a crank Trigger or a cam trigger we could possibly make it work with the stock distributor. If we were able to replace the three sensors that the OBD1 distributor has we could possibly get rid of the distributor completely

    The stock dizzie has a cam sensor integrated into it.

    Then it may be possible to use the stock distributor. If anybody would like to donate a stock fuel injected distributor I'll be more than happy to test with it.
