[dbug454]

hi i'm new here, and i im needing help i got a unfinished Honda accord 92 with a jdm h22a obd1 from a friend he got just about ever thing done other than wiring and he gave up and sold it to me.

Now im not to bad at wiring stuff. And as far as cars go i can mostly get around them to fix stuff what ever needs fixing on my cars i do, and i catch on purity good but im getting stuck. and i need help!

i'm not fixing this up to race or any thing at less not now i just need a car my diesel trucks crank went out!!! so this is all i have to drive so thats not good so i'm in this till i get this ruining!! im low on cash and not much work right now, any-who any help will be awesome, i have the h22 ultimate swap guide with wireing but i need more info then it has i will post pics of what i have. thanks every one i look forward to being on here! i may ask dum stuff. but hang in there that's how we learn

[dbug454]

ok so i was going to take pics of each sensor and plug and wire colors and info and post it and maybe u can look at it and let me know if its right. maybe this info may help others i will try and keep it good looking if i can lol heres a over look on the motor kinda messy i know but i think i have most of it right

plz look back from time to time as i add stuff i have to do a job today so i will be back later to post more, and if u have any ideas on how i can lay this out so as to help others let me know. and if u need more info let me know



to start off whats is this? and do i need it? its on the fire wall

That is an absolute mess. There are wires there that I don't even recognize.

looks like he "attempted" to do the obd2 to obd1 conv. and gave up. the valve on the firewalla is actually a solinoid for the rear engine mount was this car a auto?

Easiest thing to do, go buy a JY stock harness for your exact stock motor/tranny. Install it and run 4 wires. 3 to the Vtec solenoid and one to the knock sensor. Run the knock sensor wire and two from the Vtec back to your ECU and hook them up to the right pinout on the ECU(Look it up cause i am lazy) then the 3rd wire from the Vtec, run it to a solid ground. Then connect the wires to the VTEC/Knock Sensor.

This is WAY easier than trying to figure out your rats nest of wires.

Also because you have an external coil on your stock accord, you will need to change a few wires on your dizzy (there is a right up somewhere for it) or get a stock USDM H22a4 dizzy for direct plug and play.

[deevergote]

That really would be your best option. Rather than trying to figure out the rat's nest your buddy began, just yank it all and put it back to stock as much as you can. Then the threads on this site will be much more helpful to you.

Also, some important things have to be done to properly mount the H22, especially if you're using the matching transmission, and if the car was converted to manual from automatic. If that's the case, you'll want to be sure it's all done properly before you try to drive it, or you'll be breaking axles like crazy.

Yea, holy hell thats insane.

All wires should be routed together and the length of each should fit in the least ammount of harnes(s) required.

Someone had probably NEVER wired anything in their life. I used to build electrical panels for a mining company, and even the REALLY overloaded wired boxes didnt even look close to that slop-fest.

Honestly man, either buy a harness or get to work :/ I'd hate to have that job. Theres really not that many wires in an engine bay though. Hell i could do all the wiring in 1 day without problems.- soldered and marked- but it would be nice to have all the correct wiring color schemes. Its no good for resale if all the wiring is harbour freight orange colored

Out of curiousity, could the engine harness from the h22a work as well? Will the plugs connect to the accord body harness?

[deevergote]

No. It would probably take more custom wiring to use the H22 harness on the Accord than it would to modify the Accord harness for the H22.

Good to know

[dbug454]

haha ya its a mess, i think i will get a JY stock harness all tho i wud have cleaned it up lol and yes is a auto transs he says he thinks its a jdm 96 prelude and in US 96 was obd2 but japan 96 is obd1

i have the autozone wiring diagrams i dont have any books tho lol

i wont have time to or a way to get the JY stock harness till next weak.
do i need to get any plugs ends from the JY? or other stuff from the junk yard?
and is there any good oneline wiring diagrams?

thanks dudes

[deevergote]

I can barely understand what you're saying. Please type like a big boy.

Take the entire wiring harness from a junkyard CB. Try to get the same year as your car. It'll make life easier for the minor things that differ from year to year.

[dbug454]

lol sry about the typing, and your right thats what im going to get from the junk yard, do i need any extra plug ends for rewiring any thing? like the egr seems to have the wrong plug on it? or am i wrong?

[TracieS]

When you get a harness get it for your year a 90-91 has different main plugs than a 92-93. And leave the harness lommend and every plug will be were it will need to be or before you pull the JY harness label it there. And then I would cut off the ecu plugs (off the JY car not your car) with a little extra wire left on it to make your vtec and knock wire to plug into your ecu.

[dbug454]

ok im back, so i got bad news cant find a harness!! they are all cut up really bad, good news is the mess of wires that i do have, don't scare me much. i just need info. also win im done the wires will all have covers on them.

ok so im going to start with the

"intake air bypass solenoid"

i have added the 4 wires to the ecu. but pin a17 already has a pink/blue wire there and on my wiring diagram is says its a IAB solenoid and there's a plug out side that's the same pink/blue

so im guessing i don't need to add the IAB pin a17 wire to the ecu?

is this the IAB?

thanks dudes
