Harness Problem....

[GSDKinked]

Alright so I have received my PowerFC and realize an instant problem.....3 row gray plug and I have a 2 row gray plug. So now my question is can I use a Rb25DET neo harness on an Rb25DET S1?

[l0nestar]

I'm going out on a limb and saying 'no'.

Wrong sensor / plug combo.

ggggggggrrrrrrrrrreeeeeeeeeeeeeaaaaaaaaaaaaaatttttttttttttttt

various plug changes in the NEO harness besides the ECU plug, such as the CAS, MAF, Injectors, O2 Sensor, TPS, Main harness to coil subharness, etc. Not worth the hassle IMO.

Well what ever you plan on doing we have the parts needed:

R34 NEO engine harnessR34 NEO ECUR33 RB25 ECUR33 RB25 Power FCR33 RB25-S2 Wiring Harness

Let me know if I can help.

Ummm how about a trade lol + $$ on my end if need be. lol

pretty pretty pretty please

return it or sell it and get a proper pfc.else make a jumper harness to go from the neo ecu to the r33 harness.using a neo harness on an r33 engine is a headache, wires are routed differently and injector style is different.

Well here's the kicker....dude I bought it from ALREADY spent the money so I am basically SOL until 1. I decide to do a paypal initiated refund (would screw him over) or 2. "Exchange" it for other parts he has to offer and try and sell those to recoup my money OR try to sell a PFC for an engine no one really has....

This jumper harness is piquing my interest though...

Well Carl H has stepped up to the task of making me an adapter so we will see how this fairs in a week or so.

so around 2 years later, I'm having the same problem...but backwards lol. I have a rb25 neo and I need a harness to fit the rb26dett gtr power fc that I got

[Carl H]

same answer as before, sell or return the 26 fc and get a proper neo one.
