So i just received my harness from Rywire and i must say it is beautiful! ver very nice, except for one thing... there is no Vtec pressure sensor clip! so i called peter up and he said that its not a big deal and it can be quote "bypassed" first off my question is, this will throw a CEL right? and no vtec? secondly does anybody have any idea of what he meens?

 

You can just solder the wires together a clip isnt necessary, the connector just makes it easy to remove the harness later. Find one from a junkyard and solder it on.....

 

what i ment is there is no wire at all... check it out yourself...

ef i just got mines as well wanted to know did you ever get an answer as to why they didnt put that plug in because mines is the same way?

 

i have rywire and same thing for me... but i have jdm ecu and jdm motor and i dont have the sensor at all....vtec kick.....and no cel

 

i have the exact same problem with my harness from rywire but when i called peter he seemed to be getting frustrated with me when i wasnt understanding how it can be bypassed id rather not bypass it personally i would like to have all clips and sensors how does one go about wiring it in?

 

That's why I do all of my own wiring, I also find it funny that he calls it "mil spec" I would not doubt he has no idea what specifications the military calls for when it comes to wiring.

 

I think the "mil-spec" is referring to the military style quick disconnects only. Don't get me wrong Ryan is a good person and I have no doubt the company is good as well. But I prefer my Rex be built by me and no-one else.

 

without the oil switch its cleaner and since they go bad its better to bypass them anyways...its hondas way of making vtec idiot proof..so you dont run the engine in vtec with low oil....all you have to do is bridge pins d6 an a4 on the ecu and that bypasses vtec oil pressure switch....xenocron website has it in more detail...you want a wire tuck but want to keep all the wiring...something has to be lost...

 

I see. Yea I have nothing against Ryan either, I just don't agree with it being called "mil spec"

I've got to disagree there bud. It's nice to have idiot proof things. I enjoy the fact that my new VW has **** tons of idiot lights, from there you pull out vagcom and go to town diagnosing. But when it comes to wiring, I am very ****, and I wouldn't leave out a connection to bypass it just for the hell of it.

 

i agree with clipsed i would NOT like to leave anything bypassed or disconnected i want everything hooked up and working properly

 

you already paid the $300+ for the harness why not send it back and have them fix or add in the missing plug. this way, if something does go wrong with it, they will be the ones to have to fix it. you wouldn't want them saying "you altered the harness so we can not be help liable for any it being wrong or not working."

contact ryan and see if he can add in the missing plug

 

Holy crap it's not complicated.

First of all the VTEC pressure switch is actually not necessary for VTEC to function properly, and most JDM engines lack the VTEC pressure switch altogether AND their ECUs do not even read for one.

Secondly the "bypass" is extremely simple, and is done at the ECU. You simply scotch lock/piggyback/solder the VTEC signal wire and the VTEC pressure wire at the ECU at the plugs that go into the ECU.



You can piggy back D6 (VTEC pressure switch) to A4 (VTEC signal/solenoid) and this fools the ECU into seeing the VTEC oil pressure signal from the signal from the VTEC solenoid itself.

Rywire didn't screw up. They simply allow for a that much cleaner harness that is visible, and you make a slight modification at the hidden ECU plugs.

I don't work for Rywire, nor do I have a vested interest in them. They fixed a botched dual point to MPFI harness (on a previously owned EF) for me and even stayed on the phone with me long distance for a solid 15 minutes while I sorted out a screw up at my ECU plugs from a previous owner.

 

or why not just run the fvcking wires to their correct spot? this is not hard. you are just being lazy. if you noticed what was missing and where it goes then run the dam wires. if you don't know then search for it.

 

BTW:

You guys would undoubtedly never attempt trying to run a JDM B series engine in an OBD2-equipped car as it requires *GASP!* bypassing a CKF sensor that is built into an expensive-*** oil pump. You can buy a brand new oil pump, bolt the CKF sensor on, or simply scotch lock/piggyback/solder two pairs of wires and be done with it.



This is by no means a ghettofication by eliminating the VTPS - it's quite literally "cleaning up" the under hood wiring a touch more.

 

That defeats the very purpose of buying an expensive, clean engine harness though. You'd have these nice, slim wires running to mil-spec clean connectors, and then this lone, ugly *** wire running to the VTEC pressure switch when it is NOT NECESSARY AT ALL!!!

This is stuff that has been done since the late 90's/early 00's guys! Guys running JDM B swaps on rechipped P28 ECUs have had to do this since day one!!! I cannot believe such a huge deal is being made about piggybacking a single freaking wire at the ECU.

 

vtec switch is useless..it cause more harm than good...i had problems with my vtec going on and off when it felt like it...after i bypassed the switch never had a problem...i have an obd2 car i did the bypass on the obd1 conversion...so my wiring is untouch...just remeneber to disconect or eliminate the plug...on my next build im using a jdm vtec solenoid from a type r head with no switch...

 

thanks for the input guys i know what i gotta do now hopefully the OP figures out his issue as well ill make sure to post pics of my build

 

is the rywire harness made just for doing wire tucks?

 

the one the OP purchased looks to be made for tucking purposes. but rywire does make stock looking replacement harnesses as well.

 

so i can just tell them to make me one for wire tuck and the wires will be long enuff?

 

no, look at their site. it shows that they make the harness with the gray sleeving to allow it to blend in with the motor and transmission color when they are clean of course. you can ask, but i wouldnt be surprised if they charge extra for elongated harnesses. i know i charge a lil more for custom mods to the harnesses i sell.

 

Pretty sure it is just look on their site lol

 

it really doesn't say good things about Rywire's customer support if this thread exists in my book.

 

It really doesn't say good things about your reading and comprehension skills (or lack thereof) if you think this is an actual customer service issue when in fact it is not.

Did you actually READ the topic, or just skim and make a snap judgment, and jump on the bandwagon that says you have to do all of your own wiring? You are the exact type of person that makes businesses cringe. Rywire didn't make a mistake here.

The problem isn't with the harness.

THERE IS ACTUALLY NO PROBLEM HERE AT ALL

If a person cannot piggyback one single wire to another at the ECU plugs then he/she doesn't even need to be working in his/her car. I spelled it out and even showed the pin locations, etc. It takes less time than a freaking oil change, yet ignorant people are making a big deal out of it.
