rke_011 Posted August 1, 2012 Report Posted August 1, 2012 Can anyone tell me where these plugs/wires belong on a 4age? I believe its an AE82 loom but could be wrong? Also, the motor is a 4A-GEU and looks like the Dizzy uses a different plug compared to the loom plug? Can these be matched to each other or are they not compatible? most wiring was simple but just a few things and I'm hoping you guys can help without me un wrapping all the loom.. Things that are not connected are MAP/AFM? Not sure what the loom is for? Dizzy TPS Coil/Ignitor TVIS (I think) Any help would be great.. Thanks in advance. Quote
rian Posted August 2, 2012 Report Posted August 2, 2012 It's been a while since I looked at my loom so I may be wrong but here's what I think the plugs are: In the forth picture, the yellow plug near the water inlet looks like a map sensor plug or air temp sensor plug. In the fifth picture, the black one pin plug looks like the power for the injectors, blue two pin plug looks like the plug that goes to the noise suppressor thing near the coil and that would mean the green plug is the dizzy plug (all the dizzy plugs I have seen are yellow??) In the sixth picture, looks like the cold start injector plug (could be TVIS but TVIS is normally a bluey green plug?), though it's hard to say without seeing where it is on the loom. Quote

rke_011 Posted August 2, 2012 Author Report Posted August 2, 2012 cheers for that, the sixth picture is actually a large plug which i assumed would have been for the TPS (seeing i can't find the plug) but it is too large for that? so I'm a little confused Quote
rian Posted August 2, 2012 Report Posted August 2, 2012 How many pins on the plug in the sixth picture? That could be the AFM, and in that case the yellow in the forth picture would be air temp sensor I think. Quote
ke70dave Posted August 2, 2012 Report Posted August 2, 2012 TPS is 4 pins in a row. http://i47.tinypic.com/2ljrjx0.jpg the yellow round plugs are either distributer or air temp sensor on the inlet manifold. they are both yellow from what i recall. MAP from a quick google search appears to be round and yellow too... the green round one goes to your ignitor. http://imageshack.us/photo/my-images/442/p1010007oz9.jpg/ that white wire with a few wires attached i THINK is for the 02 sensor. thats the only one i can think of with shielding. essentially if its got a plug on the end, it can only attach to one device. if it has no plug get the color of the wire and compare it to a wiring diagram. or follow it back to the ECU, get the ECU pinouts from club4ag.net, and see what it sais.

Hmm, are there different TPS? I'm pretty sure the one on it has 3 pins but the plug has 4 from memory? I will have to check and confirm tonight.. Thanks for all the help guys, hopefully this will be the majority of it.. One last question, looking at the connectors I have and where they go, I'm pretty sure that my dizzy has a different connector compared to the loom.. Dizzy is marked as a 4a-geu are there different dizzys? can the plug be changed to suit? or do i need another dizzy? Quote
ke70dave Posted August 2, 2012 Report Posted August 2, 2012 as far as i am aware there is onyl 2 type of distributers for the 4age 16V, 4 wire and 3 wire. potentially different plugs, but the wiring is the same for all the 4 wires and all the 3 wires. do these to plugs plug together? Quote
rke_011 Posted August 2, 2012 Author Report Posted August 2, 2012 from memory no, will have to confirm, but the plug from dizzy looks a lot bigger.. So you seem to think that they should still work?? The motor originally had a different dizzy i think 4k in it so they could run a different ECU.. unsure why, but I'm thinking of trying to engineer so i need standard ecu.. But never realized that there were different variations in all the little things. surely it can't be hard to sort out TPS and Dizzy and MAP or AFM(wish i knew what loom was for)... will have another play tonight and see what i can figure out.

Subaru_kid Posted August 6, 2012 Report Posted August 6, 2012 (edited) Is it a map or afm? can't be both... map usually sits on the firewall side of the intake mani and has a vacuum line and a plug leading to it. Pretty sure that green plug goes into the coil/igniter Here is the only pic i have of my old bigport for reference. HTH Edited August 6, 2012 by Subaru_kid Quote
rke_011 Posted August 8, 2012 Author Report Posted August 8, 2012 cheers, yeah i know it can't be both. But it was running an ac delco or something ecu before with a 4k dizzy and an afm.. but I'm not sure if my loom is afm or map.. think i may be best off buying another loom and knowing what its from and what it is...

rke_011 Posted October 8, 2012 Author Report Posted October 8, 2012 Can someone take a picture of the plug and colour of wires that connect to dizzy?? Think my plug has been chopped.. Would be appreciated if you could May help me narrow down where these wires are... Cheers Quote
