Accurate wiring diagrams

I just bought a 99 base model with an H23A and am wanting an accurate full wiring diagram. Not like the ones in Hayes and Chilton that are generics that are over 50% inaccurate because they try to cover every model in one diagram. I'm willing to buy one even. Thanks

P.S. I searched and only found fragments, mostly interior body. I'm needing to do work around CAN bus and sensors mostly and don't want the overhead of tracing dozens of wires through the main harness.

They and Chilton are half-accurate at best.. I've had dozens of those manuals over the years, even for motorcycles, and the wiring diagrams are always like -if it doesn't work for yours just guess- and that's usually how it plays out. Especially around PCM and TCM and BCM wiring where it is actually needed.. I had one for a '75 Honda motorcycle once that only had a timing controller, and they didn't even get that one right..

I know there is one online company where dealerships and shops source them from and they actually bother to separate the model diagrams.. I forget the company though..

Re: Accurate wiring diagrams

Have you tried the helms electric trouble shoot manual.

I've found in my case the book is pretty acurate for my type SH, minus the color of a wire here or there between connection points...like the fella who assembled for example C344 to C134 had run outta solid black and used black/gray...

Yeah the company is called Helm Inc.

They produce the Factory Service Manuals used by dealerships across the US.

Below is a link to a listing on ebay. I know they are cheaper than 100, i bought mine for 60-70 direct from Helm.

1997 1999 2001 Honda Prelude Shop Service Repair Manual Engine Drivetrain Wiring | eBay


I know there are PDF copies online somewhere available for download, I don't remember where, but I have it on my computer. I can upload a copy some how.

Re: Accurate wiring diagrams

If you can find the ISDN for it you can probably get it at 1/11 the cost on Amazon or ebay, else it's $35.00 on ebay with the electrical troubleshooter
