such great and valuable info here! I bought an ap2 cluster too.
I'm still thinking on how to make the harness without touching the oem cluster harness. That cluster plug idea is great, little pricey but great. I was thinking about depining the oem plugs and pass the wires trough the bottom hole, then twist the cable and apply silicone glue instead of solder them so it's easy to go back to stock.

Anybody tried to mess around with the EEPROM 93C66 chip to modify the odometer?

How much does one of those run? What else is needed for the conversion?

 

pm me here, or at one of the links below my sig

 

this question might have been asked but i can't find it. Is there a difference between the 92-95 vss for auto and manual? All the ones on ebay don't specify. I currently have a hydro gsr tranny in my 91 civic, which has a cable vss obviously.

 

That's a nice wiring setup, to bad it was not out when I did my swap. Would of been so much easier with your harness. Big props for making that harness.

 

Thanks. Thought I would give the ef family something Noone else wanted to tackle.

 

Wow, that is awesome!

 

Hey, what were the lexan pieces you were talking about to cover up the gap in the cluster? Is this something you ordered? If so can you tell me the link, or what it's called. Thanks so much

 

Can you please PM me the AP1 Pinouts and what I would need for a 91 ED9 CRX. in South Africa.
