Default 94 Accord LX ECU wiring diagram, vehicle speed sensor wire.

Does anyone have a 94 Accord LX ECU wiring diagram? I need to identify the vehicle speed sensor wire. Can I pickup the VSS from somewhere inside the engine bay? Also, which wires on the oxygen sensor (4-wire type) are the signal output and common.

Thanks in advance for any help.

I have the diagram btu no way to put it on the net... my suggestion would be to go to your nearest Advance auto and look in the Haynes repair manual they sell there

I have the Haynes manual, but it didn't have the ECU details. Perhaps there is an updated version. I bought mine back in '96. Thanks, I'll check. In the mean time, can you answer the question on the O2 sensor wires? There are two black wires, a white and a green connected to the sensor.

Thanks for the info. Incidentally, the 2 black wires are for the O2 sensor heater.

About $4K because I upgraded the MSD boost timing master that came with it to the amplified version. BTW, if you are planning to get one for the Accord, be prepared to do some bumper modifications. Unless you have an aftermarket front bumper which has more room to fit the intercooler.

I have a Honda Service manual for my 95 Accord LX. They are all the same. I had the same problem installing my HKS SLD, but after studying the book HKS supplied, and my Service manual, I figured out that the orange colored wire going into harness number 1 is the one you are looking for. Don't quote me on this though. If you are still interested, email me and I will make sure that's the one you need.

What shape was your engine in when you put the turbo on, fresh from honda or a tuner? or a slightly used? I would like to stay with the F motor, and this car for a while, and the turbo option is heavy in my mind.

Thanks for the wiring info. I decided that it was easier to pickup thge VSS from where it taps into the transmission. That way I don't have to mess with the ECU. Wish me luck. Click the image to open in full size.

I bought the Accord new. But every 3 years I get tired of it so instead of buying a new car, I figure it would cost less to modify this one slightly. The only thing I had on it before adding the turbo was CAI , DC Sports cc header, strut tower brace, custom exhaust.

I'm still working on the turbo install (it's a weekend-only thing). I hope to start up this week. The finish on the F-MAX turbo kit is awesome... really good work. I only wish that it was a true bolt-on for the '94 Accord. I had to do some modification to the front bumper, power steering cooler and a/c lines, just so that the intercooler would fit (I was hoping to keep the car looking fairly stock). Never-the-less, standing in front of the car, there is now a really mean-looking intercooler staring back at you. I also have to relocate the battery to make room for the K&N filter to the turbo intake. I guess you can't blame F-MAX because the 94 Accord does not have a lot of room to play with. In fact, I originally wanted a supercharger, but there is none available because there is nowhere to put the blower so that it can line up the engine drive pulley.

Sorry for the long post. I give more details when I start up and get a dyno run. Click the image to open in full size.
