I just got a h22 motor and trans that i am putting in my 92 prelude that had a H23. The wiring that came on the H22 what cut up bad so i was going to use the wiring off the H23 but there are 3 sensors that there are no plugs one is the v-Tec One has something to do with the fuel psi and the other is a map sensor i think. Does anyone know how i need to wire this or do i even need them?? HJeres a pic

 

you can ditch this valve between manifold and fpr. and connect fpr directly.

 

that is what i was thinking. Any info on the map sensor.. One other question the H23 has a external coil and the H22 has a internal coil every thing pluged up i just have the extra coil plug that has no where to go.

hook up the map that is not on your throttle body. atleast thats how mine is hooked up. redline in arlington did my swap

 

Anyone know if that's a map sensor? and do i need it. I am running a jdm ecu so it may need it.. Anyone??

 

I am running a jdm h22a with the usdm p13 i used the map sensor on the firewall, I have ha no problems, but since you are using a jdm p13 I’m not sure what you should do. I would leave the map sensor on the fire wall and see if it throws any codes.

And you can use the internal coil dizzy that came with the swap; you just need to jump the external coil plug with a 20 amp fuse. There are three wires on it, jump the two that are right next to each other. Not the blue wire. You can also cut them and put the together, but i like just taping the fuse in there

 

I will try it then go from there...Thanks

 

run one or the other, both worht the same way, jsut that the stock map is in the box, so its hooked up via a vac line, and the one u have is on the TB so its pulling vac directly from the TB, no biggie,

I think i will use the fuse like you said.. I am just going to use the map that's on the fire wall.

 

why not just use the H23 dizzy? then you don't have to mess with any wiring.

 

yeah i used map on firewall and h23 dizzy plug and play

 

If you use the JDM dizzy it still plugs right up. All you have to do is put a fuse in the coil plug and it looks alot cleaner.

 

so having a dangling coil connector with a fuse hanging out of it looks cleaner than it plugged in to a coil?

 

Yep because the wire with the fuse in it has a cap off a relay and it sits under the dizzy!! cant even see it

 

haha awesome, oh yeah u can get rid of that map sensor on top by swapping to an obd1 TB, one from a 92-95 h22/h23. that way u dont have a map sensor sitting around on top doing nothing.

 

Yeah when I did my swap, I found that the H23 TB was actually a lil bit larger, so I used it for that reason as well, and I used the external coil dist from the H23 as well, and I like that I can easily use a different coil for the setup if I want too.
