So to update this problem i was having: it was definitely the key switch

I was going to try and sand the contacts on my old one but i dropped it and springs flew everywhere. I ran to the junkyard and pulled two off a civic and delsol both are the same

I installed it and checked the resistance and read 0 just like it should across the supply voltage wire and acc wire ( blk wht and blk yllw)

Now i just gotta redo my engine harness and i should be good to go

Just to warn you, the official pinouts that were posted (post 1, C101 and post 23, C131) are completely unhelpful and downright wrong. Here are the correct pinouts as I have physically verified by dissecting the engine and dash harnesses by hand:



This in no way reflects on the person who was helpfully sharing the official (albeit inaccurate) documentation

Former User

I never heard this before, so I'm skeptical.

See my edited post.

Physically verified every wire:

Former User

No offense, but I'm still skeptical.

So what exactly was incorrect in the pin outs?

What year and transmission HX did your wire harnesses come from?

tech8

I am trying to understand what are the errors. Different years and whether it is A/T or M/T affects the wiring color and whether there is a wire at the cavity.

Former User

^This (also OBD2a versus OBD2b; 99-00 HX CVT [OBD2b] versus 99-00 HX 5-speed [OBD2a])

You need to read the pin out diagrams very carefully.

tech8, do you have access to AllDATA?

tech8

I have access to some Honda info.

Former User

I envy you.

Can I get that link?

tech8

It's secured info.

I haven't looked at all the diagrams you posted in this thread; but, I do not see any inaccuracies in what I briefly looked at. Yes, Honda info. can contain errors (like anything); but, I don't find anything materially inaccurate here.

None taken, none given.

Mine applies specifically to the 96-00 HX MT. The difference between the Y5 and Y7/Y8 that is the rear O2 sensor comes out of C131 instead of over by the front O2. 99-00 and other variations aren't different in any way that matters to us.

I posted the pic to show that I tore the harnesses down and physically followed each wire to its conclusion. I put a D16Y5 into a CRX, fully converted to OBD2 with an OBD2 scan port and SCS port. It passes safety and emissions (twice now) and has been daily driven by the owner for over a year. No CEL. It throws a code for fuel tank pressure sensor which the CRX does not have, but it doesn't go into limp mode for that. Trouble code but no CEL.

Compare my tables to the official documentation. 13 out of 22 pins on the C131 say "PGM-FI". That sounds fun. How shall I connect a wire to Programmed Multi Port Fuel Injection? Might as well say "car".

Examples of unhelpful info on the C101:
"Fuse 15"
"(G101)"
"(PGM-FI)"
"Charging system"
"Gauges"
"Ignition system"
"Starting system"

Mine which tells you what the wire is coming from or where it needs to go. Try doing a conversion with the official pinouts - I did.

The tables I posted aren't completely finished yet, but the info there is 100% accurate.

You are not posting any specific errors in the connector diagrams. Do a side-by-side comparison listing specific pins that differ between your connectors and the connectors in the diagrams.

Ok ron i got another one for you

Do you know or does the book show anywhere how much current some of the sensors draw?

Based off the stock sizing of the wiring i would think not much. Im going to be adding in some deutsch connectors and need to know if i can get away with the smaller pins which is rated for 7.5a or if i need to get the regular sized pins and connectors

Former User

I don't have that information, but maybe you should say specifically what connector pins you plan to swap.

Im going to be using 2 12 pin dt connectors to split the harness in half

So all my wiring will be going through those except for the starter signal wire. I might put a small relay in the engine bay and trigger the signal wire with another smaller gauge wore just to keep them all in the same connectors iono yet

What harness and what specific connectors are downstream of the splitter connectors you plan to install? I fear giving you an answer without knowing precise details. Otherwise, you might burn up the new harness or start a car fire.

The engine harness.

All the wiring that goes to the engine?

I dont know what youre trying to say.

I tried makin sense of that diagram the other member posted for the green connector but it doesnt really make any sense. I wrote down all the locations before but i lost it

Heres a pic

I found my notes


ron can you confirm these pins?

Former User

Do you know what connector or its location? It seems to be a 22P connector. Okay C131.

Yes, you identified all the pins correctly.

yea c131


I jus went back to the last pageand seen tech8 posted a pic, I was looking at the pther guys pic it looks like I got it all in the right spots

Former User

Yep, all are matched correctly.

baller status

You can clearly see all the problems in the comparison pic you posted. How should I make it any more obvious? Virtually all of them are listed as "PGMFI" which I take to mean the ECU. It is not helpful to know that these wires are coming from unspecified pin on the ECU. You need to know where they go. From the ECU to what? How would you like to wire up the pins, to the specific devices I name or to "PGMFI"?

Disregard my info if it offends you.
