I'm trying to install an Apexi Rev/Speed Meter. I need to tap my vehicle Speed signal wire from the ecu. Does anyone know the wiring diagram for the ecu. My hunch is that the speed signal wire pinout is #45, yellow wire. Any help would be appreciated.
thanks,
Brent

i believe the speed signal wire is yellow with a green stripe.. not certain. If i remember to look, i'll confirm tomorrow.

hey, thanks. Its a 95 ecu right? Is it pin # 45. Not too sure if the ecu wires vary with the years.

Yes, it's a 95 ECU. I forgot to look this morning (just like i forgot the disc with the pics of my new IC, etc) but i'll let you know the color, at least. You can find it that way..

I tapped the yellow wire, pin 45 at the ecu. I thought I traced it perfectly from the speed sensor located in the tranny all the way back to the ecu. I hooked up the Rev/speed meter but there is no speed readings. Oh well, any one ever install one of these things?

If you can find it, the vehicle speed sensor is towards the back of the tranny, sort of under the intake manifold, next to the battery tray. I'm pretty sure it's a yellow wire with a green stripe. (i never go by pinouts, just the colors. All the wires are color coded ;-)

Erm it's cold outside I hope you appreciate me going out to check the wiring and such. I go check my HKS Type one wiring I have a 95 also.
It's Yellow with White stripe dude. ^_^

Does anyone have a list of all the wire colors and what they are?
