JDM 86 ENGINE BAY WIRING LOOM

[JDMJNKY]

I HAVE PLUGED IN ALL THE PLUGS ON MY AE82 4AGE ENGINE AND JDM MANIFOLD. THE ENGINE RUNS ONLY ON AEROSTART HAVENT LOOKED INTO Y THE INJECTORS ARNT WORKING BUT I FOUND 2 SPARE PLUGS THAT REACH TO BEHIND THE PLENUM CHAMBER, LOOKS LIKE THEY MAY GO 2 SUMMIN ON THE FIREWALL, ON THE WIRING LOOM AND WONDERED IF THERE IS SPOSE TO BE AN INJECTOR MODULE OR SUMMIN? GOT A YELLOW CIRCULAR PLUG WITH 3 PINS AND A BROWN RECTANGLE 2 PIN PLUG.?

1 should be the map sensor?

[psychofox]

look on club4AG for the wiring pinouts and trace the wire colours.

or take a picture and I will have a look.

[JDMJNKY]

damn do 4ags have a map sensor? thatd be the yellow plug im guessing

[parrot]

Yes, almost certainly the yellow is the MAP sensor. The brown will be the start injector time switch which is mounted in the sensor block on the very rear of the cylinder head. The one that has the two sensors. The other sensor on this block has a green plug

[rthy]

adm ae82 have 2 brown plugs, 1 is mounted at the rear of the block (as above) and the other is to the rear water housing for fwd

[Gilly]

pictorial answer for you my friend.

yellow plug is for the map sensor as you now know, pic shows where the brown plug goes (like Parrot says)

picture is of my JDM loom so should be the same as what you have.

you can use an AE82 map sensor you will just have to change plugs, as only JDM MAP sensor use the circle plug. if need be i know someone who has a few JDM Map sensors if you want a JDM one drop me a pm and i'll suss it out for you.

[Gilly]

MAP sensor does bolt to the firewall i just put there so it was in the picture http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif

[JDMJNKY]

cools cheers lads got the yellow 1 figured now but what does the brown 1 go 2 exaclty cos the rear water housing already has the green and brown plugs on it. ive got a 4ag and a a 4agze and both running am computers this is the first sotck comp 4ag ive dun.

[rthy]

if ur running the jdm water pump setup then u wouldnt have the adm fwd rear water housing?
try running it with out

[Gilly]

thats the only brown plug i have on mine, and there are no other "spare" plugs to speak of.

any chance you can get a pic up?

EDIT: just realised its an AE82 engine. do what rthy said

[JDMJNKY]

cheers heres a brain teaser. does the ae82 map sensor have 3 wires aswell as the jdm86

[rthy]

yea i have a ae82 loom and running with out the rear water housing (plug not in use)

all bigport map sensors should be the same?

[hilux08]

the maps are the same plug,picked one up from recker off a twinky and it plugged in

[parrot]

Bigport map sensors are identical, other than the bracket that bolts them to the body. If you use an AE82 sensor you simply need to make a right angle bracket to bolt it where it is meant to go on an AE86. Plug is identical

[Gilly]

hmm my engine apparantly had an ae82 map sensor as it was running a ae82 loom in a Ke70. i have a JDM loom and had to get a JDM map sensor as the plugs were different

[hilux08]

wait...sorry i ended up using a ae82 loom so thats why it plugged up easy for me. I am an idiot http://www.ae86drivingclub.com.au/forums/emoticons/blink.gif , heard it here first http://www.ae86drivingclub.com.au/forums/emoticons/biggrin.gif

[hilux08]

but my plug looks exactly the same as gilly's one.
ziptie ftw

[JDMJNKY]

just rang wreckers Ae82 same as 86 cheers for all help lads found theres spose to be a injector main power wire so maybe that aswel be the problem

[parrot]

AE86 on the left, AE82 on the right.

The brown plug at the bottom right is for the cold start injector time switch. If it doesn't look like that, you will have to put a pic up. Yes there is an injector main power wire but that doesn't have a plug in it.

[riceburner]

What colour is the cold start injector plug meant to be???

Is it possible you have accidently swapped the cold start with a injector plug.

I bet a pic would have this solved in seconds.

[Gilly]

my cold start injector plug (JDM LOOM) is black

[parrot]

The cold start injector plug is black, but the cold start injector plug is not the same as the cold start injector time switch sensor plug (which is brown as per the photo above)!

Cold start injector is situated in the main body of the plenum.

The cold start injector time switch sensor (i.e. the thing that signals to the ECU how hot the engine is and thus how long the cold start injector stays on for is located on that sensor block on the back of the head.
