Well after all of the work on this car it PASSED Ca. smog test and the tech told me that the car runs cleaner than 85% of the cars in it's classification. WooHoo the car is now in my name!!!!!

That's a great result. Congratulations!

Does anyone know if I can harvest these connectors from a complete civic 92-95 engine harness? I've seen harnesses on eBay and figured I could just buy one of those to get the 4 needed connectors but I don't know for sure. Thanks!

You can harvest them, but avoid eBay if there is a junkyard in your area. I bought all of the terminals/ connectors I needed for around 5 bucks and spent a couple hours splicing it all together. Finding a legit vx harness is hard. But using the connectors from other crashed hondas( not just civics btw) is doable. Finding the ecu in the junkyard was the only part I couldn't find. Good luck

Thanks! I'll do that then. I guess there is a scrap yard close to my parents and by my house. I should be able to find the 4 connectors out of those 2 places I'd think. I just bought a federal ECU and an 02 sensor so once I can make the cable I'll be good to go!

I just purchased a 94 Civic VX California version. I will be driving it to Colorado where I live.

I was looking to do the Federal conversion and I have read through your thread as well as a few others on the net.

I have two questions about the conversion.

1.) If I find a 5 wire O2 sensor, wire harness and Federal ECU will it all be "plug and play" on my VX without having to make/create a custom wire harness?

2.) I have read about needing a Federal version intake manifold and EGR control box to make this conversion complete. Are those two things necessary?

You'll need the wiring harness, 5wire sensor and the computer, that's it.

I made my own wiring harness, using Honda connectors, and it's all plug and play.

I'm going to sell my red 93 cali VX, since I found a white Federal (with shift light). The white one is going to be my back up daily driver, and I don't need anything fancy. That said, I don't think I'll be adding a lot of value telling someone it's a federal version. I can always keep the new 5 wire sensor as backup.

No need to source a Fed Vx engine harness. Just follow the DIY, it's very easy. And the shift up light. Forget about it, use the MPGuino. Best tool for driving fuel efficiently.
