Wiring Afm. Go From 5 Pins To 3 How?

[avalanche]

hi i want to wire in a 5 pin afm green sticker to a 3 point plug that use to have a pink sticker. which wires go where/?

thanks

i assume your new afm is a z32, so unless you have an aftermarket ecu or piggyback ecu, wiring in that afm will make the car run like crap.

Z32's have 4 wires [counting the earth] and orange stickers, well mine does anyway.

[mad082]

well what would have 5 wires? cause i'm pretty sure all 33's (both series 1 and 2) are 3 wires, i think series 2 has a pink sticker, and i'm not sure about the series 1 colour.

[skybarge]

the green sticker ones are RB20de/20det/25de off the R32

don't think you want to wire that onto a 25, unless you have a Rb20e R33?

In that case, two of the wires are for the hotwire/clean function, can't remmeber which ones though :S

that means this guy has sold me something that is no good to me.

None have 5 wires..

R33 S1's have the same wiring as the R32 GTST's; that being 4 wire - 2 earths. The AFMs are the same; both green stickered.

The R33 S2's run with 3wires - a single earth. Pink stickered.

Splice the 2 earths from the AFM together; its as simple as that.

I would assume the S2 and S1 afm's are interchangable providing you splice the earths together or splice it apart depending on which way you are going.

I base that on the R33 PFC's run the same airflow curve and map reference without issues. So their callibration should be identical.

yup

[Cubes]

Not necessarily.

Read my above post mad.

The ONLY difference between the 3 and 4 wire afm's is one runs 2 earths. Simply splice them together and done.

[mad082]

but his has 5 wires, not 4, so i doubt it is a skyline afm, in which case it will more than likely not work with the stock ecu.

if it is that he just can't count and it only has 4 wires, then i agree with you cubes that it will work just fine.

[Cubes]

Looks like you agree with me then.

All R32 RB20 and R33 S1 AFM's have 5 'pins' (not wire). BUT only 4 of them are utilized via the plug (wires).

Go pop the plug off yours now and you will see what i mean.

[mad082]

oh ok. i had a series 1.5, so it had the series 2 afm, and i try not to associate with rb20's, LOL

just kidding.

[Cubes]

lol thats fine.. I no longer associate with them either.

Mind you there's a few making some good usable power these days.

[mad082]

they are too much of a lag-monster for my liking. even in stock form.
