Hey I couldn't find diagram of the ECU wire harness. Do any of you have one? Here's my problem. I bought this 98 Prelude like 7 months ago & the guy had the 'Fields VTEC controller' on there so I took it off. Well anyways point is the car's been sitting in my garage for about 6 months & I just realize I have LOOSE/UNCONNECTED wires. SO yeah, I'm selling the car now & I need the diagram to be able to reconncet the wires. If any of you could help me I'd appreciate it. Thanks.

Check a service manual or go to http://www.apexi.com

 

Yeah but I'm not trying to connect the VTEC contoller. I'm trying to see what all the wires coming from the harness & going to the ECU do so I know what's disconnected. I tried un-doing the steps on the Apexi & feild thing, but that didn't help. I have some extra wires still not connected.

I will find another on later (at work now)

Do you still have the fields?

 

Can any of you guys help me. Do you have a detailed pic of the ECU & wire harness??? I know someone has to.

I can't find it right now but you should be able to just match up factory colors. your going back to stock right?

 

Yeah back to stock. The thing is it's idling funny & I'm pretty sure it's just something that was disconnected from the ECU. I'm getting a CEC of 3 & 72. So I'm HOPING it's cause of the wires.

Check your map sensor wire in the ecu harness, a loose connection can bring up this code and make the car run like s**t. Also on the apexi site it show a diagram of the wires used to install a vtec controller so you can see the cables that they used to install the fields and check them out.

 

You know what... your right. I guess that's my best bet. Thanks man.

That's to a OBD I. I have a 98 Prelude, it's a OBD II if I'm correct. THANKS though. That's an awesome diagram for real. Let me search the site where that came from, maybe they'll have the same thing but for an OBD II ECU.
