RB20 Question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Anyone know what pin outs connect to which wire for the RB20DET series 2 motor? My MAF is J60 and I had to make a new pigtail for mine as it was snipped. If anyone has a wiring diagram or anything of that matter to help it would be greatly appreciated.

The R32 service manual will tell you which wire colors on the engine harness perform which functions (MAF +12V, MAF Signal, MAF Ground), and you should be able to match that with a J60 MAF pinout to get it wired up. I'm not sure they read the same, but then again I don't waste my time with RB20s

:lol: Bahh blew out my 3rd KA so I said screw it and got an rb20 for an excellent price. I prefer I6 over I4 any day. Do you know any reliable sources for getting the FSM? I saw a diagram for the pinout of the J60 MAF on either this site or NICO but I'm unable to locare it now.

Hope this helps.

Thank you 100x over! That's the EXACT image I was looking for!

. You saved my ass! Edit: Searched through FSM, I take it that the black wire with dots is ground (second from right pin), black with white stripe is power (right most pin), white wire is signal (left most pin) and the solid black wire (second from left pin)?

Okay got the car running basically 100% but I STILL need the MAF wiring diagram as my car is entering trouble shoot mode.

Any help would be appreciated, thanks!

If rb20 and 25 series 1 use the same maf... then why are the grounds in different spots?
