I am building an EF9 Sir, and need the wiring diagram for the entire car, I have searched for it but can't seem to find it anywhere...

I have the under the dash wiring and possibly the rear harness as well but some of the wires have been cut so I am having a hard time figuring out what goes to what???

I am also trying to convert the ECU plugs to OBD1 status, because I am going to be running a USDM Del Sol B16A3 engine with a USDM P30 ECU, so I need to figure out what the the wiring diagram is, so I can switch the plugs to the OBD1 harness for the ECU...

If anyone can lead me in the right direction, or where I can get this info it would be greatly appreciated...

Thanks

 

If going OBDI, here's what you need:

- obd jumper harness, it's plug n play, plus you hook up 3 wires
- obdI dizzy
- 4 wire heated o2 sensor

and of coarse the ecu which you already mentioned

Thanks for the RYWIRE tip I had been on that site before and didn't notice they actually had a jumper harness for the JDM ef9 sir OBD0 - OBD1. That should help alot...

If I can't find the real JDM EF9 vtec car wiring diagram I can at least try to use the jumper harness as an example of how to hard wire the new OBD1 plugs onto the OBD0 harness on the EF9 I have... I am trying to splice and solder the new plugs to pass smog in CALIF, I've heard the REF's won't approve a jumper harness for the ECU.


If any one has a tip where I can find a English version of the JDM EF9 Sir wiring diagram,???? for the car... need help

Thanks

 

i am not sure if people have run across a factory service manual from japan i remember someone was looking for one but i dont think he found it. What i have seen floating around is a European manual on the Internet. The European manual might have what you are looking for if not call rywire and ask him if he can make you a harness for you and your application. Another possibility might be working with a usdm si harness (cabin and enging harness ) and extending the wires to were they need to go.

 

Have you gotten the car already registered??

 

No haven't got the car registered yet I am still trying to find the best way to register it, been doing a lot of research, they seem pretty hard to register.... I have talked to DMV in Sacramento and they told me what i need to do to get it started so just trying to get the paper work ready>>>

Any ideas or helpful tips??
