Hello,
I am doing a S5 swap into a S4 rx7 and I need the S5 dash harness. I have been looking all over for a complete S5 dash harness and can`t find one. And I have looked on here. Does any body have one or know were I can get one.

Thanks

 

I don't think the harness is different so just use the s4, I just swapped a s5 dash into an s4 and everything worked fine.

 

The S5 harness is indeed very different. But I believe you are referring to the emissions harness. You would be far better off retro fitting the S4 harness to work on the motor.

 

The EM or emissions harness has the fuel injector plugs etc and fits on the engine. It comes into the cabin and attaches to the Front harness and ECU.

The Front harness(red) runs from the passengers side to the drivers side........enters the engine bay and runs fwd to the radiator area and over to the right side of the engine bay. It also connects to the Instrument harness (yellow)and the engine harness (blue) on the left side of the engine bay.

Engine harness runs on the left side of the engine bay and connects to the Front harness.

Look at the jpg and select a harness that your interested in. The harness are color coded as shown in the first jpg.

 

I thought he was referring to swapping an s5 DASH into an s4. In which case I don't have A/C, emissions, or original ecu. Sorry about the miss information

 

Yeah, there's no simple "dash harness" to swap in. The front harness goes all over the place, and should be tons of fun to remove/replace.

 

I've done them you do not want to get involved in this project if you don't absolutely HAVE to.

 

Why with just a little electrical tape, shrink tubing and spit, that harness will look like new .......in about ten years.
