so i already know there is a **** load of write ups on this swap but i want to know if instead of making my own wiring harness if i could just get a stock wiring harness from a 94-95 honda accord ex and make it work on the prelude motor since all the plugs are the same.... will it work?

I've never did the whole harness swapping thing before - but from what I read, yes, it'll work fine. Though you'll still have to wire up the ITB's (and VTEC if your civic didn't have it) from the strut tower to the ECU.

 

not good wit some abbreviations....ITBs?and how do u wire them in bcuz my chassis is an ex so it comes with all the options.... and also if i buy the swap mounts for an h22a into a 5th gen chassis what rear motor mount bracket do i use stock d16 or stock h22a?

You can't plug a prelude engine harness into a civic body harness, you'll need to put your stock engine harness onto the H, add/extend wires as necessary.

 

i know i cant use a prelude harness which is why im asking if i can use the ACCORD harness... in the 94-95 ex accords all the body harness plugs are the same as mine so the wiring harness would plug right in.... and my h22a1 has an external coil can i just order an msd cap and coil and run it as if it didnt come wit the external coil from factory?

I'm sorry, didn't mean ITB's - you don't have ITB's - meant IAB's.

Fuckkkkkkk harness swapping, not worth it at all.

Just take your stock harness and change the ends on the dizzy and injectors, IF it's a different OBD...then you gotta wire up the resistor pack...which is pretty damn straight forward. If you have an EX you have the wiring for VTEC, if not, you have to wire it (all 2 wires), and the IAB's need to be wired in.

It's gonna be more of a headache harness swapping than it is just rewiring the existing harness you have on there.

I got told on here quite a few times to swap harnesses...I can't justify spending ~100 bux extra instead of 7.99 on a box of crimp connectors for like 3 plug-ends.

 

its all in the write up!
extend o2 sensor
extend alternator
iab's
and add vtec if you didint have it before.
took me about an hour to do all of it~
and i did the egr too.

 

ok so i should use my d16z6 harness but splice in the h22a1 injectors and the plugs for the dizzy... then how do i wire in the IAB's and the resistor pack?

 

bump- need to wire the engine what do i do to make my z6 harness work need details on how and what to wire in

 

if im reading the thing on the internet corectly it says the idle air bypass is the same as an idle air control valve which i have on my stock d16z6 why would i have to wire it in

 

ok this is what you doo!
dump the resistor pack
get 97 and up prelude injectors.
they will work with obd1 and no resistor
the iabs are a bitch.
after getting it to work i ended up scrapping it after breaking 3 different sensor valves. cause i had nowhre to mount that ****
just ran a vacumm line straight.
no big difference you loose like maybe 7 torque under 4500

 

ran a vacuum line straight to where?

 

straigt from the manifold to the little round ufo looking thing.
on the right side of the mani
understand?

if you post a pic ill tell you the number

have you ever heard ITB's on an H22? it will make a grown man cry

 

ok so i just need to wire in the appropriot idle air control valve plug and wire my z6 harness then the rest is plug and play right... i really dont wanna expletive this up all the head is very appreciasted


bump

 

idle air?
if you look at my post above.
that is all i had to change,
everything else went right in.
plug and play!

and if it didnt i used the sensor that cas originally on the d and swapped it over

lol.

i thought you said iab;s for a second.
i was going to say "ninja please" lol

 

ok now my next question if i make a block off plate for the egr valve and dont wire it in the motor will still run correctly.... right?

 

yes you could do that.. check to our forum (prelude forum), most people are going to help you. I hope u guys dont mind reading on your section.

no.

it will thorw a code and retard your timing. making your car slow.

UNLESS YOU have a CHIPPED ecu, to turn off the egr

 

my friend has a jdm h22a in his 94 accord and it doesnt have an egr valve or external coil and we plugged my ecu into it and it didnt shoot any codes- no CEL came on and it didnt run any different than it did with the jdm p13 ecu
