Airflowmeter question URGENT HELP REQUIRED.

[tydon]

hi just bought a purple airflow meter and it doesnt fit my loom plug is 3pin instead of 4 can i simply swap the plug from my old blue airflow meter with the purple one so the loom matches ???????????

[tydon]

well i opened up my purple airflow meter and are now confused LOL there are 3pins inside that under the copper shielding as compared to the green or blue airflow meter which is 4pins.

In need of desperate help....

there is no problem, you simply have the wrong airflow meter. the colour and part number dictates the version/type. they are not interchangeable. replace like with like

hi im having trouble with my plug to the AFM ive bought a purple AFM for which i was told was what i have to use. i cannot find a reasonabably priced 5plug purple AFM and decided to go yellow injectors and orange AFM. have just got the orange AFM and its also a 3pin plug im pulling my hair out tryna figure a way to wire one of these damn AFM in.

I currently have a Orange AFM

a purple

a green

and a blue

My uncle has a GTB BG5A legacy wagon same shape and loom etc. hes running yellows and orange AFM and i have noticed his is also 3pin plug..... need help and dont really want to spend more money on yet another AFM... can anyone please tell me if there is a way to splice it in (uncles GTB looks like its been spliced).

Find a cefiro afm plug and rewire it to your cable.

As cefiros use the 3-plug for the coloured afms, you'll notice a lot of suby afms aren't coloured as stock.

gonna try wiring mine again on fri before work, will let ya know what goes where if mines all good, found a pic or 2 of what it should be

but map sensor plug fits the afm itself ^^

if i can resplice my 5pin plug to a 3pin plug il be able to run my current purple airflowmeter/tdo4l/2S(ECU) combination till i get 1S(ECU) and vf22 to run orange 3pin airflow and yellow injectors. thanks jimbob and 94 leone.

both topics merged as they are the same story.

from memory..

5pins are +12 / Ground / Shield / Signal / unused

3pins are +12 / Ground / Signal

have a look through the main single turbo conversion thread for the the wiring diagrams, page one

v3/v4 3plug ecu has 3pin AFM

v1/v2 4plug ecu has 5pin AFM

wait.. if your loom is 5pin AFM.. then surely the 1S or 2S ecu won't plug into the loom anyway, you need to repin everything.. mate, just find the correct AFM

[tydon]

i am repining the 4 plug ecu to a 3 plug tomorrow have everything mechanically done just need to sort resplicing the AFM plug to run both purple and orange. i have the correct coloured AFM just not the right PIN.

[kamineko]

cool, ok

try to explain the whole situation when asking urgent questions. from our end, imagining what your trying to do gets difficult

if your re-pinning the ecu plugs, you'll have all the wiring diagrams and everything else worked out - the afm plug will be a piece of cake, don't stress

your also going to have to change the TPS / ignition system / MAP plugs but again i'm guessing exactly what setup you've started with

[tydon]

yup i have printed off all the conversion and wiring pinouts. forgot to mention in good description off the complete job im doing sorry about that. and yup was just abit worried seeing as ive bought 3 AFMs and all have been 3pin plugs was just really confused lol.

thankyou much appreciated.

Im working with a an EJ20H 4 plug ecu BG5a i replaced the intake with a v3 intake/grey injectors/purple AFM/TDO4L and 3plug 2S ecu for a start i just want it running.

I have yellow injectors and orange AFM just waiting to get more koin together to get matching turbo and ECU.

I reused my TT loom and IAVC and TPS sensor plugs all matched and plugged up have got all the wires and pipes in engine bay all conected up in the correct places.Just need to sort the wiring for 3pin plug and repin the ECU which will be doing tomorrow so with any luck would like to be on the road tomorrow.
