EP3 Pinout (S2k Cluster)

[MadLorEP3]

I did my ap2 cluster wiring last summer so I completely forgotwhat I did...LOL...I had no prior experience with wiring at all. I am as nooby as you can get. So if I can do this then anyone can. It took me about a week. I've been getting alot of pm's about this. I posted this on crsx awhile back and came across it again today. hopefully it will be of use to someone. GoodLuck.

Very helpful thread on crsx...Read this first before you start

The ECT module will require +5V power and a ground. Tap the 4 lines out to the following:

White (Signal Input from ECT Sensor) – B8(Red/White) in the ECU wiring harness (connector B middle of 3 plugs)
Green (Signal Output to Temp Gauge) – B5 on the S2000 cluster
Yellow (+5V) – E5 terminal 5 yel/blue 5v vcc3 (sensor voltage) Connector E on ECU
Black (Ground) – bolt holding ecu in place



Next converter you need to connect is the speedohealer. This will convert the analog signal from the RSX into a digital signal for the S2000 cluster. Like the ECT module, the speedohealer will require a +5V to +12V power source and ground. Tap the 4 lines out of the harness to the following:


White (Signal Input) – B5 blu/wht (green) (Vehicle Speed Signal Input) (there is no need to tap directly into the tranny)
Green (Signal Output) – B7 on the S2000 cluster
Red (+5V to +12V) – A10 on the S2000 cluster
Black (Ground) – A17/18 on the S2000 cluster

When your done, you HAVE to first input a calibration value in order for your speedometer to start showing your speed
Start with this calibration value if you like
I went with +4096.5 on my ep3
At freeway speeds above 60mph my speed is right on the money
but at lower speeds around 35mph my speed is lower by 1mph

the next step for me is to actually write down which ep3 wires go to which ap2 wires...

Pix of the old setup

Still not done with wiring-havent had time to work on this...
And this is just a temporary fix
I will eventually use a thin sheet of cf or maybe even have a custom enclosure made of fiber glass






most recent pic (May 2010) still not done with the housing...

Pretty cool man. Your interior is hot.

I didn't know the S2000s had EPS like the EP3.

Can you list the parts needed and where to get them, like those converters. You have convinced me to get trying at this. I can get a cluster for ass cheap
