I have a RHD conversion 1994 rx7 fd from japan, I built myself. it's working pretty decently except its misfiring because the ECU isnt grounding the air pump. I grounded it myself with a wire and it runs smooth. I'm not sure why my ECU is acting up it's the correct one for the car I'm pretty sure. N3a7 for a JDM manual car. so everything should work fine. I'm noticing problems like a few wires that have no connection as well. one under the master cylinder. and one circular one near the air intake by the front most fusebox. I could really use some help finding a JDM wiring diagram if you have one or know where i can get information on the JDM wiring diagram. so I can trace what is wrong with my ECU that's causing the grounding problem and hopefully the other stuff.

 

One, if it's under the booster, will likely be the fuel pump resistor....which might have been removed. Only thing I can think directly in the master vicinity is the level sensor.

Might need a pic of the round connector, does it have an O ring at the end?

Doubt there's much difference on earths rh v lhd in the electrical manual. The ring terminal at the ecu end screwed down?

 

What do you mean by "RHD conversion" - you mean it's a US left hand drive car you swapped over to Japanese right hand drive? Or it's a car imported from Japan?

You're going to have a job tracking this down. It sounds like a lot of wiring was messed with. You will have to get the wiring diagrams and step through things.

You can also look at getting a PowerFC and turn off O2 feedback control, that will disable the need for the air pump.

So yes it's a LHD car and i cut the firewall and all and slapped in a RHD stuff because it came crashed and with a front clip RHD for cheap. so why not. but all the wiring is RHD JDM wiring so it should all work but its having small problems. And id like to keep my cat enjoy a stock FD first before doing emission delete.

I will try and get pictures later this week. I'm at School rn and need to go home to work on the car.
