Rb26 Pfc On A Stock Rb20

[pullmeonr32]

That just tells me the differences between the 2 Ecu layouts, I need to know how to wire the different wires of the 2.

Yes, so make your rb20 plug the same as the 26 plug.....

[pullmeonr32]

How is that going to help?

[Ben C34]

Are you serious?

So the connections on the 26 power fc go to the right spots on the 20 loom.

What are you trying to do? What answer do you want?

Ok I'm installing a rb26 PFC on my rb20det.

I know I need to do some wiring swapping and linking in wires I.e like injectors and afm.

But there are wires that's don't match up (in my eyes) that I don't understand what to do with them ( numbers 5,14,15 on the rb20 wiring list) where do these link in with the rb26 wiring?

Thanks

They don't. They are only used to run the RB20 Automatic transmission. In other words, if you car is manual, they won't be part of the loom, the pins will be blank and you won't have to worry about it. If your car is auto, then the computer won't cut ignition on the upshift and you'll quickly destroy your auto trans.

You my man are a saint!!! Thank you!!!

Which is what I said. After you have done the above advice your rb20 plug will look like the rb26 plug.

Cant say I didnt try.

You just needed it simplified to the absolut max, sorry I couldnt make it that simple for you.

Good luck with it all.

Ok about to get my car ready for mapping. Would you guys recommend using a rb26 Ecu plug? Or just keep the rb20 one?
