Hey guys, got a new mod:

Essentially, it's a Heads Up Display of your Tach or Speedo readings projected on your windshield.

The Tachometer feature works fairly accurate, but is off by about 200rpm at idle.

Wired it up, didn't come with a specific wiring diagram for ECU, but got a wiring guide's from Apexi-usa.com. I followed diagram H2-A specifically from RSM GP Diagram. Great guides there, but I guess telling us what color the wires are is too much to ask?

Wasn't sure which ECU I had specifically according to their charts, but I have a PR3. Wired it up, the power, ground, and tach work fine, it's the speedometer that isn't reading... Anyone have a wiring diagram or know which wire is the one I need to tap into?

I checked the misc guides and manuals looking for the speed signal, but didn't work.

ALSO, I have to set the # of speedometer pulses, what is the correct number for my application?

Any help would be appreciated, thanks!
--- UPDATE ---
I have some daytime pics and video...

Sorry for the shaky hands First time letting someone else drive my car.

 

On my 2000 EX, it's a blue/white wire going into the gauge cluster.

 

woah what is that 127??

 

That might be in KM...

Anyone know which wires?

 

Anyone know any sites that have ECU wiring diagrams?

 

Did you check to see if there's a blue/white wire? It's a speed signal wire for 99-00 Civics. It could be the same for other cars as well.

 

I didn't have a chance to look at my ECU yet, but if I remember correctly, should have been a white wire with a blue stripe... unless I clipped on the wrong pin, I'll have to double check tonight. Thanks

 

This is gonna sound nuts, but check the Haynes manual. It has a GREAT wiring diagram for 5th gens. I can look it up tonight if you don't have one. Just hit me up on AIM. Bakeoff2

 

I have the Haynes, they have a bunch of wiring diagrams in the back, got a headache from trying to figure it all out, that and having a swap might make things different, thanks! I'll hit you on AIM!

 

UPDATE:
I had the right wire, it's the snap connector splice that didn't contact... works great!


Records top speed.
