K-Series Swap Wiring Explained!

[@krx_kid9104]

I've been running the Hybrid Racing Kswap Adapter Harness/Sub-Harness in my CRX for over 10 years. Never had an issue with it. Only electronical issues I've had, have always been in the factory CRX wiring (old, crusty wires).

[@FrancisD]

Very good information here.. Please make more videos with how this should route/look in the car. Awesome info appreciate it.

[@destrkn]

I'm planning on k swapping my new beetle at some point and this video will help me out a lot. Thank you in advance lol

[@GooseWurkz]

Excellent explanation, new to k-swap world and just wanted I needed, look forward to purchasing this conversion harness and many other hybrid-racing goodies!

[@mrs_radrod]

Thank you. I needed this video for a long time. I’m brand new and over my head with an engine swap and this is such a good explanation for all the harnesses and why/how they work.

Finally someone puts it into English thank you

[@kleanstreetchannel]

I’ve done at least 6 swaps wiring , I always recommend this . Simple and reliable. 96-98 only needs charge light, coolant temp and fan switch. 99-00 is a little more work but still simple .

[@joelperkins8656]

i have a 96 and looking at the installation guide on the hr website it says to find the a connecter from the chasis harness on the passenger side and i cant find it. does that means i dont have to splice in all the other wires. only the ones you mentioned for the 96-98?

[@bobbydelamar606]

Is there another video of hooking it up? Where do those other wires (green and yellow) go? I'm down to wiring in my K24A2 CRX. I have the Rywire and CRX conversion harness.

I also need this info

[@ShiftyReaperGaming]

Can you please make a video on how to do the immobilizer bypass you sell just get into high details

[@alomechanthasinh4079]

Step number 14 in the conversion harness install guide: "Route the C101 blue connector on the Hybrid Racing harness to the driver side of your chassis. You can use the sup- plied zip ties to secure it nicely under the dash. NOTE: 2000- 2001 INTEGRA. Remove pin 7 Blue wire and connect it to pin 14 Blue wire. Pin 14 has 3in of wire that runs into the harness that you can pull out. This controls your TACH." Thanks in advance. Can you guys illustrate this in a video? *2000 Integra GS Auto to manual with 07 K20Z3 swap.*

[@HyperCut_Films]

Great video Hybrid Racing! I’ve bought your conversion harness for my EJ9 Civic here in the UK and cannot wait to get started on my build! Most of the Hybrid Racing parts catalogue is being bought soon haha. Cannot wait! Great information and I’ll be using it to follow! What’s happened to the EK9 build also? Love that series! Thanks!!

[@hybridracing]

Awesome! The EK9 is on a dolly, covered up sitting in the corner of the shop for now haha. We will have more videos coming in the next few weeks.

Slight bit of advice, possible update. MAKE SURE TO GROUND ENGINE HARNESS TO A STUD AND NOT A BOLT. Bolts wont ground out due to rubber valve cover gasket.

Sold! I just bought it, but would still love to see how you install the harness in the car. You said "we will show you in a minute" but never saw it. Is there more coming on this?

[@hybridracing]

Yes, I had planned to film it all, but since it's for an EG it was sort of specific. We have guides on our site that show the inner section of the harness. If you need more direct help, shoot us an email. [e-mail]

[@thisislargemouth5566]

I'm trying to swap a k into my old Datsun pickup. I don't think i need the conversation harness. Would I be able to run the K24 with a manual ecu and immobilizer bypass and just the engine harness? It do i need a conversation harness to hook up the o2 sensors?

[@jonnyfortin]

Are you going to post the second part of the video? Meaning the wiring under the dash.

[@hybridracing]

We have a guide on our website that shows how to connect the wiring under the dash of an EG/DC. Check that out, or email us if you have specific questions. [e-mail]

[@michaelhevezi7273]

Where would the pigtail connector plug in if you were to use it?

[@andrewsmith6064]

Which sensors do you have to change if your running a k24a2

[@dsmfury]

Better explanation than rywire

[@dangappa]

Do you make a conversion harness for a cross platform engine swap? Honda k24 to Volkswagen chassis, longitudinal mount engine.

[@hybridracing]

We offer a universal conversion harness which can connect the K24 to the 02-04 Hondata KPRO. You'll likely need a special RWD style K20A2 engine harness, but it should work. Check Rywire or WireWorx for custom engine harnesses.

[@thonmoybhattacharjee3041]

How come ya don't make 05-06 harness conversion

[@KarsenHardi]

Need help. My car is all gutted no more dash. Looking for a setup like engine harness to ecu with a monitor. What can you recommend on a stock k24a engine on a eg hatch gutted

[@Otjmore]

Do I need the 02 sensor installed before to get it started??

[@hybridracing]

The car will crank and run without o2 sensors, however it will run pretty poorly until you have the primary wideband installed and functioning.

[@syloluon4969]

One thing i hate about being in Cali is the state ref laws. We were able to use jumper harnesses like these and pass ref and now we have to use a donor vehicle to get the original harness etc. Be great if these jumper harnesses were c.a.r.b legal .

[@briandalucatero696]

I have a tsx k24z3 what harness should I uses on my Honda Civic 2000 ek

[@AcuraLvR82]

I bought your conversion harness and had a voltage fluctuation issue with the main o2 plugged in. Made the engine run really bad and caused lights to dim up and down. I have 4 massive grounds all are pure copper to shiny bare frame. Ended up having to run o2 power straight to the battery and relay trigger from 12v switched under the dash. Any idea what may have caused the issue? Everything else on it seems okay and the car is a 97 integra ls with a k24a2 on kpro4 pnd ecu and base rsx harness.

[@hybridracing]

I have encountered it before, but it is nothing as severe as what you describe. I'd send our support team a message so we can get more info. [e-mail] Otherwise, isolating the relay and running power directly to the heater is the right thing to do. Just make sure it has the proper size fuse.

[@grant6985]

I had to do the same thing. My tuner had me cut the wire and reroute it to another power source. Was kind of disappointed after the amount I spent to be honest. Granted, this was 2 years ago, so it doesn't much matter anymore haha. I also had my card info stolen and had $1000 spent in Baton Rouge after buying from Hybrid Racing. I reported it to them and got told it "definitely wasn't them..." Even though they're out of Baton Rouge, it happened a few days later, and I've never been there before in my life.

[@hybridracing]

@@grant6985 I'm sorry to hear about those issues. Our customers and service to them has always been paramount throughout the course of our near 20 year history.

[@cameronvogel9796]

Awesome stuff! So is the secondary o2 “heater” plug a lot of time just tucked away and not used? Or am I missing something

[@hybridracing]

Yes and no. If you are running KPRO, you typically do not use it and can turn off the sensor's function inside your calibration. That is what happens 95% of the time. If you are using a stock ECU (say a PRC Type-R ECU), you'd have to have it connected and plugged in since the ECU will be looking for the secondary sensor. But to your question, yes, you'd usually just tie the wire up and stick it out of the way.

[@derrick2949]

Can i run stock ecu will i have trouble with key to start it

[@anthonycr2976]

I bought the hybrid racing conversion harness and the hybrid racing temp sensor. I installed the temp sensor on the hybrid racing radiator and the temp gauge doesn’t work… any feedback ?

[@hybridracing]

Make sure the radiator is grounded.

[@MrZeroLag]

Do I need to have a 02 sensor if my car doesn't have a cat (crx) Can I just use a wideband only?

[@hybridracing]

If you are going to use KPRO or an aftermarket ECU you can run just the wideband and you will not need the O2.

If I’m going with a Haltech Elite ECU do I still need a conversion harness if I’m running their digital dash also?

[@hybridracing]

If you are going to use a Haltech ECU and digital dash, you still need the engine harness. I would check out the new Rywire K-series engine harness that is compatible with the Haltech ECU. It's what Eric Kutil uses in his race car, and the same setup we will use in our Drive-By-Wire EK9 with the Haltech 1500.

[@btibbs626]

My issue is I have a k24a2 out of a tsx will this tucked harness still work? I wouldn't want to pay 500 if it isn't plug and play. I don't have any idea about wiring. I just bought a battery tuck kit with charge harness but it doesn't have a connecter on it it goes to fuse box, battery, alternator, and starter. Wiring is just so confusing to me. If someone can point me in the right direction it would he greatly much appreciated!

[@gvainola]

alot of things are for RSX. Do they work on EP3?

[@justinjolly9177]

What if we are using a k20z1 full swap? Which engine harness and conversion harness should I use?

[@hybridracing]

If you plan to use our conversion harness, you'll need to use the 02-04 RSX engine wiring and ECU etc. Basically, all of the parts that are in this video.

There is a way to have K-swapped cars CARB legal. You will need to contact your local ref service and ask for advice and the rules to follow.

[@gregorytoussaint509]

CAN I JUST USE THE OEM 02-04 RSX TYPE S ENGINE HARNESS INSTEAD OF USING THAT RYE WIRE?

[@hybridracing]

Yes you can, however it will not be correctly lengthened to fit inside of the EG/EK/DC2. The OEM harness also has connectors you won't use, and it may not route the way you want. If you are ok with that, then yes, the OEM K20A2 engine harness will absolutely work.

[@marvinreyes6270]

Hi sir how about k20a9 manual can use the complete wiring

[@Zeno_Citium]

would this setup work on a FIRST GEN (86-89) integra?

[@hybridracing]

Yes, if you use our universal conversion harness.

[@kseries20-24only]

@Hybrid Racing What engine management would you suggest for a 2009 FG2? I'm leaning toward a 06 RSX-S swap with supercharge for a track focus build. Until I get the blower installed, but start adding bolt on's, what would allow me to manage those and someone to tune the blower when it arrives?

[@hybridracing]

If you have a 09 Civic Si FG2, I'd suggest Hondata Flashpro. There are tons of maps available for that car off the shelf, or you can have a custom tune created for any specific setup. Check out our website, we keep them in stock.

[@mizike55]

Does this Rywire and EK conversion harness combo support your AC kit?

[@hybridracing]

Yes, although the AC system is chassis-based and has nothing to do with the engine or conversion harness wiring. The AC compressor is controlled by the engine bay connector, so nothing on the engine harness will connect to it. Your AC pressure switch is also part of the engine bay wiring, so again, the engine harness won't have any effect.

Yes

[@hybridracing]

@ray claudio, send us an email so we can get more info. [e-mail]

[@Fyxxterzc]

Where's the charge harness? Built into the rywire?

[@hybridracing]

The charge harness is a separate piece that is included with the Rywire harness. Your alternator and starter wires are built into the harness, the only part that is not is the actual direct power link between the battery. Obviously, there are a ton of ways you can run your battery, but that is really the only thing that's sort of custom to your specific chassis situation.
