I need your help, i've searched everywhere and can't find a link on what to do if using a vx engine harness on a b18c. what mods do i have to do? everything i find is people using the gsr harness. also i'm going to be using hondata s300. all wiring is 94 vx.

 

anyone care to shed some light.....

 

plug and play mostly.

If you have OEM intake mani you need to run wiring for the butterflies.

If you use GSR ecu then you will need to re-wire O2 sensor from 5 wire to 4.

Check sticky at the top, many detailed pictures on this whole process.I'm pretty sure its stickied.

its plug and play there is one sensor which will have to be extended and thats the .... cant remember the name but its the one that goes on top of the manifold. what year motor? i did this exact same swap but i had a 92 eg with a 99 gsr

 

its plug and play but you would still have to do the 7 wire to 4 wire o2 sensor modification.

It's actually a Jdm b16 head with a Jdm b18c bottom end also it's a type-r intake manifold. are you talking about the white sensor that sits right behind the fuel rail with 2 philips screws?

yes

 

If your using the VX engine harness, the o2 sensor plug is a seven wire I believe. Been a while since I've worked on one. You'd have to use a 4 wire o2 sensor with your B series thats why you'd have to do the 7 to 4 wire conversion. I could be wrong but thats what I remember...

Here's the link to do the modification..

Ok so just the 02 has to be modified, thanks for the link. anybody know if somehow cause i'm using hondatas300 maybe the 02 doesn't have to be modified? how about the egr the big ugly box on the firewall?

 

the ugly box is not used. you can remove that. and technically you dont have to run the o2. you could run a base map that doesnt look for it. oh and there will be 2 wires that arent used on your harness its the ones that are connected to the white sensor that i told you about.

 

Nice, Thank you Now we know
