hi. uhh i have this type-s s motor and i am swapping it into my 1992 honda prelude. we are almost done with all the prep work to the motor and will be readdy to drop it in soon... the thing is ive been looking at the wiring harness and it lookt like there will be things that don't hook up because the relays are different... like for example the mastaer cylinder... which is pretty important. the ecu came with three plug ins that were cut and the motor came with 2 from the wiring harness that will plug in in place of two of them ... but the third one i am not sure... i am thinking that that is for my dash and all the accessories and i will need to have all those wires rewired into that third pluggin for the ecu. am i right? now the last two things i am wondering about is if there is some type of wiring conversion kit i can buy from somewhere that will plug into the motor and then into all the stock relays and it will already be ready to run inot the ecu...? it would really make things simpler if there was something like that. my final ? is that the ecu came with a fuse bot but no lid so i dont know which fuses are for what and also the box didnt come with any of the relays that plug into it and only 2 of the relays from my old fuse box matched up...but that was on the old wiring harness.... does anyone know what to do about that situation?.... yea i would definatelly appreciate the help since my time is limited to get this swap done and i have basically a month to do it...should not take that long at all though maybe another week. only working on it a couple hours of the day. but yea everythings going good with it i just am not a wiring person and i dont really know **** about the ecu's. mine is p13 by the way. thanks for the help

 

bump because this guy need sum help

 

your psot makes no sense at all. i think you need help with writing in english first.

as far as wiring the Type-s swap, you use your stock harness and mod it to fit.
You can ignore all teh sensors on teh ATTS unit (big 90lb pile of **** on the back of the block going into the tranny).

 

uh yea sorry i had no clue what i was talking about..i was real lost. i am on the right track now. uhh the motor does not have atts. its lsd. then i have to use my h23 harness with fuel injectors possibly. then i have to use my obd1 distributor and then wire for vtec and pressure switch. and then it will plug into an obd1 ecu. the only other thing is a few of the connectors might have to be swiched from the new harness to the old one. example speed sensor connector... ohh and yea it was the abs relays not master cylinder... i am an idiot and didnt realize what i was looking at.

 

the ecu plugs into the chassis harness. the reason you re-use the h23a1 harness is that it also will plug into the chassis harness.
if it doesnt have atts its not a type-s engine, with lsd it could be an sir s-spec, or optional lsd engine.
if its an obd2 engine you will either need to find obd1 injectors or remove the resistor pack and use the obd2 injectors with swapped over plugs.
