I would'nt mind if anyone can contribute to identify the plug from number 5 to17
and 22 to 25.
This harness is for FI. The end of this wire are connected to all sensors such as:
coolant sensor, two camshaft sensor, crankshaft sensor, starter, alternator, sparkplug & coil, injectors, AIT....etc, etc, etc.
I want to know where are those plugs going (numbered).

I also would like to know (below the big picture with arrow) the big black wire.
Is this wire positive bat. +??. This wire is bundled along with the fuel injection wiring shown. I think the end should go to the + of fuse box (big black wire).

Appreciate any help.

 

Your big black one looks like a coil wire.

 

Since we don't have a single coil, does that line split to each of the individual coil packs?

 

There are actually 4 coils for the s2000, each of them are built into the ICM's on each plug. Coil over plug.

 

Right! That's why I'm curious what a single big wire would lead to. All I can think of based on 3ngin33r1's post is that there is some sort of split to each of the 4 coil packs. I don't have my car here now so I can't just check it.

 

I believed that black wire is connected to the fuse box +

 

Mick---if you don't mind, can u please take a look at that black wire and where that wire is connected. I believed that black wire should go inside the big fuse box + (bolted). I think this is the wire that power the FI harness...its bundled with the FI harness.

I appreciate your help.

 

I would be happy to, but can't for another 3.5 hours when I go visit my S at the body shop. I'll be happy to snap a few photos of anything you direct me and send them over if you can wait 4-5 hours total.

Just let me know!

 

Thanks...I can wait.
Also, Anything you can see from your car ( those plugs I numbered---where each plug are going). will help a lot.

 

I will do my best to get them all and post back this evening in this thread. Someone MUST have an exploded diagram of the engine bay and wiring you can use as a guide in addition.

Anyone have or work at a dealer and can retrieve one to assist? We're not talking service manual stuff, more like parts diagrams that will show and label all wiring and components for purchase.
