Ok so ive bought a standard ecu (just to get 4age running) for my 4age conversion in the starlet and also a loom from two different people of trade me. my problem is i went to make sure the plugs plug into the ecu the centre one does but the two outer ones dont. Ive been to NZEFI to see if they could do it they said they could but dont want to which is a great F#@King help (i know where i WONT be taking my car to get tuned once its done :roll:

)

Anyway just wanting to know if there are any other tuning shops in Chch that may beable to do this for me or maybe an auto sparky? Cheers

Want or wont?

Also, you could try looking up the ECU pin out diagrams online and find the one that matches the loom plugs you and and the ecu you have then chop and change the loom wires to suit.

what kind of ecu + looms are you using? 16v or 20v? fwd or rwd?

by **DXROLLA** » Mon Feb 09, 2009 6:29 pm

Wont sorry.

I was told when i bought the ecu and loom that they were both for a blue top 16v out of an fxgt. So unsure if that is correct or not

by **l1ttle_d3vil** » Mon Feb 09, 2009 7:53 pm

can you chuck up some pics of the ecu + loom plugs?

ae82 and ae86 run different plugs on the comps maybe thats the issue or red top blut top incapatiability

ecu plugs should still be the same. its just the ecu pin-outs which differ.
bluetop vs redtop sensor plugs are different, but all the 16v ecu plugs ive seen have been the same shape.

but its easy to forget some of the plugs, so if some pics are posted we'll know exactly what he's talking about.

Got some pics of me phone for you

can't count the pins on the ecu but those loom plugs are for a bluetop.
the loom should plug into the 1st and 2nd slots on the ecu, and i'm guessing you're missing the plug for the far right?

if they don't fit the ecu, you must have the wrong ecu (maybe 20v or something??)

by **DXROLLA** » Tue Feb 10, 2009 2:26 pm

Yeah they plug into the 1st and second slots but not the last one. So you think it mite be a 20v ecu?

by **xsspeed** » Tue Feb 10, 2009 3:22 pm

doesnt look like a 20v ecu, doesnt the third plug from the engine loom plug into the connection with the body loom, then the body loom also plugs into the ecu or something like that?

Could be mistaken from another car though

by **fangsport** » Tue Feb 10, 2009 5:06 pm

third plug looks like it could plug to main relay box or to body loom

by **DXROLLA** » Tue Feb 10, 2009 5:32 pm

Just checked the plugs its the 2nd and third that fit but not the first as you can tell from the shape

by **l1ttle_d3vil** » Tue Feb 10, 2009 6:24 pm

ok was a bit confused as originally you said the centre plug would fit and the other two wouldnt.

from the looks of it you've got the correct loom + ecu, but you're missing the 3rd plug for the ECU. this is attached to the wiring under the dash which is why it gets missed - its not part of the engine wiring, but is required to run the engine.

i haven't done a fwd loom before, but I've wired up a few rwd looms which aren't too hard so they should be near enough the same.
flick me a PM if you need a hand to get it all sorted.

cheers

Oh ok so what would the 1st plug be for in the picture? can i still use this loom or will i need to get the extra wire and plug you are talking about?

by **crispy'86** » Tue Feb 10, 2009 7:28 pm

That first plug that's square is for a front wheel drive fxgt. That goes into the passenger footwell fuse box. Disregard that one. maybe you might want the dash side plug (from the ecu to instrument cluster, gauges etc)
The AE82 fxgt's have that yellow square looking plug

by **l1ttle_d3vil** » Tue Feb 10, 2009 7:35 pm

yeah you've got the correct loom, that first plug in your pic which doesn't fit just provides power to a few things, among other things. you need wires off it for the engine to run properly.

but on top of that, you will still need the 3rd plug for the ecu. i just sold my spare one last week to a guy who has your exact problem.

by **DXROLLA** » Tue Feb 10, 2009 8:43 pm

Oh ok so what would the name of the wires i would need and do they plug into that 1st spot on the ecu? Where could i take the loom and ecu to get all this sorted for me as i have no idea what im doing?

by **repowered** » Wed Feb 11, 2009 11:38 am

could try go back to the people you got the loom off on trademe see if they still have that plug or the car the loom came out of to get that 3rd plug.

When i got my 4age with loom i had to go back and ask them for the 3rd plug lucky they had the car they were wrecking still
