im going to try and install my apexi neo. i really dont know where to start though. first off, i have a 2000 civic si. what is that considered? an EK4? i need to know this so i will know which terminal table to look at. and on these wires, do i just hook all of the colors to the SAME colors in the ecu?

 

Chassis Code list, EM1

and for the Neo install, could maybe simplify it with THIS?

 

well the instructions suck. i dont know what to do with half of these wires. i know i have to tap into my ecu and connect them but are they color coordinated? and flip, i really dont know what you showed me is for....

 

the first link is for a list of Chassis Codes, and it says this: EM1 - USDM 99-00 Si coupe B16A2

and the second link is a link to a Plug-n-play harness for the Apexi Neo, then you just pick your ECU, which would completely eliminate splicing wires, and removing it would be a breeze

 

pick my ecu? get a new one? and about those chassis codes, i know my car is an em1 but in the apexi book that IS NOT listed. it has a few different ones with b16a2 engines listed and those are....ek3, eg6, ef9, ej1....

 

no, it means pick the ECU you already have, and i beleive 96-98 is OBD2A and 99-00 is OBD2B, so pick the B

and with that website you dont have to worry about your chassis code, just pick the ECU and yu're all set, which would eliminate any splicing of the wires

 

hi i dont know about the apexi but it should tell u the body type under the bonnet on the plate on the fire wall at the back of the engine bay

 

so does this just hook in to my ecu? as far as i know there arent any open spots to connect that.

 

i understand the confusion, but it doenst go in any open spot, it goes in between the ECU and the harness that plugs into the ECU, then the harness that plugs into the Neo is already spliced off of that with the correct wires going to the correct pins on the Neo's harness.

I was confused at first with my turbo timer harness becasue i couldnt find any open spot, but then i understood

 

I have an Apexi Neo for my 04 Si and when i bought it, it came with a wiring diagram. I know that you MUST run it off the Pressure sensor, with 6 in and 6 out. As for the wiring, there are 8 or so wires out of the harness that you actually use. some you splice in to the factory harness and some you run into the Neo and out of the Neo.
