Hey mate, Thanks heaps for the replies and info! I have been near death with the man flu lately.....hence why I haven't replied lol. In reply to your last post, I don't think that particular plug exists on the smallport loom. It has a fully fledged DIAG port on the loom. Which I will be keeping. Here's the relay I have put into the factory fuse box, it had the provision for it but being carbed from factory it didn't have the relay itself in there. I've checked continuity between the pins to see where it ends up underneath. Pin 3 is all about the place.....ground? pin 1 is right where the thick white cable and b/r go in.....must be the power feed. Pin 2 and 4 are over by themselves where there was a blanking off type plug underneath, I pulled it off and hey there's a bunch of terminals under there. From what I understand pin 2 will go off and feed my COR/fuel pump and ECU. pin 4 will come from the 15A EFI fuse in the fuse box pin 1 will be from the battery. Since pin 3 is found in multiple areas, is this the ground?

Hey mate, thanks for spending the time to type up that reply. I have this for the instrument cluster, but nothing really for the dash.. Ok, I think I have the BATT sorted for the ECU. I think the plan for running the fuel pump through the COR and +b and +b1 is to add a "EFI Main" relay into the factory ae85 fuse box... I have the relay plugged in and tried to find continuity between pins 1-4 on the relay and everything underneath..pin 1 seems to lead to a pin beside the thick white wire coming from the battery. Pin 2 (will go to ECU/COR) and 4 go to a unused terminals under the fusebox (I should be able to put a connector right onto the terminals) and pin 3 shows up on a few pins.....If this is the ground pin does that make sense? Thanks.

New post in project thread!

Hey fellas, I've just had another poke around the wiring on the levin......a few things I saw left me with a few questions. Have I not been able to see the forest for the trees? I have read over and over that people use the stop circuit to provide constant power to the ECU (BATT) I noticed there was a fuse labelled as "ECU - IG"...I tested this and it provides 12v on ignition. I don't know what ECU is it currently providing power for, maybe the emissions control? There is a B/Y wire going to that that has 12v on ignition. Does it seem logical that I can use a fuse tap from the "STOP" fuse to provide constant power to the 4age ECU? Can I use the same fuse tap method to provide switched power to the ECU from the "ECU-IG" fuse? Am I an idiot? Or could this work and eliminate all the wire tracing I was in the middle of doing?

Hey mate, thanks for the reply! I had similar thoughts about using the wires going to the emissions control box in the passenger kick panel. Is this the one you are talking about? As I say the only wire that had power to that was the black yellow upon ignition.

Hey team, I was doing a bit of homework today on the 85, I hooked up a battery so I could see what had power constantly and what had power with the key in the ON position. I'm just wanting to see what I can use to power the 4age ecu with. Looking in the passenger kick panel here. This thicker white wire has 12v as soon as the battery is hooked up - would this be suitable to tap into to use as constant power for the ECU? Also to the left of this wire, in another plug, there is a white / red stripe wire that has the same constant 12v. Could this be used? This next wire only has 12v when the key is in the ON position. The green plug goes into the old emissions control for the old engine and is now surplus to requirements. Can I use this black / yellow wire for 12v switched power for the ECU? Thanks guys - I know this the most boring part of any conversion lol

Looking forward to more progress pics of the 86, looking really nice so far mate!

Hey mate, thanks for the reply! I am in Dunedin. Ideally I would like everything to run as intended....eventually....but want to nail the core things required to make it run first.....things like check engine light etc I can figure out later. The loom has the diag plug on it so I was going to keep it there. Relay wise, I would like to use the original fuse box if possible. If I need more relays then I am happy to add them in neatly somewhere. I am happy to extend the smallport loom so it can route inside the cabin nicely. For the fuel system, I will be sourcing a toyota COR. I am using the standard AE92 alternator. I have a pretty basic understanding of the charging system and what is required there, the wires will definitely need extending to get where they need to go. I have separated this wiring out of the loom for the time being as it is somewhat separate anyway. These are the main sources for info I have been using: http://club4ag.com/faq_and_tech_pages/ECU Japan AE92 90-91.htm http://www.rollaclub.com/wiki/index.php?title=Tech:Engine/A_Series/Wiring_Diagrams thanks.

Hey mate thanks for the reply! I have read that 4 wires to the 12pin plug are enough to get it to run.....these being(?): Pin 1 - B1 Pin 2 - BATT Pin 4 - COR Pin 7 - B I have a 12pin plug to fit the ECU which I can use for the above pins. Can you remember where you tapped into for pin 1,2 and 7? I can put up some pics I took today of the kickpanel areas At this stage I don't have the circuit opening relay for the fuel pump. I hope to get one pretty soon - can you buy an equivalent relay from the likes of Jaycar? So the stock AE85 alt wiring from the 3au can support the alt from the 4age? Thanks!

I thought I would update here to so people could see where I am up to. As said in the discussion, I am currently stripping back the wiring for the Engine and removing wire that aren't needed such as ones that went to the body of the ae92 and removing them from the loom. I have separated the alternator wiring from the engine loom at this point and will integrate it back in at a later point once I look at the car and see what factory wiring I can retain. Still unsure of a few things on the loom at the ae92 fusebox end of the loom. I hope this will make sense once I look at the car......it's not at my address at this point. Please feel free to comment and post pics of your wiring on your ae85 conversions - I would like to see them! Also I would like to see pics of what people have done for a throttle cable mount onto the side of the intake manifold. Cheers.

Hey folks, I got the bug again and started attacking the wiring....I began figuring it out ages ago and then stopped as my old man said he knew a guy that could do it.....but never did. I have learnt a shit load by studying wiring diagrams and looking around forums etc over the last week. I am currently taking all the old tape and shit off the loom so I can liberate some wires that aren't needed. This has added hugely to the learning process, being able to see where everything goes and being able to trace the wires everywhere is making all the difference. I understand the smallport loom is short and needs to be extended - this is what I am looking at doing next as I want to have some freedom with mounting the ecu inside the car. Looking forward to making more progress. Can anyone advise on the following? + locating wires in the cabin for BATT, B1 and +B1 for the ECU.........if anyone can advise on the best source for these would be great! + wires in the kick panel area that have 12v on ignition that can be used for powering coil/injectors or whatever. +any tips or anything unexpected that people have discovered while doing this wiring? Thanks!

I might be making a mountain of a mole hill but its unfamiliar territory for me haha. Yeah there are all the ECU pin outs on club4ag. Do you know if the dash wiring on the ae85 is the same colour as ae86? It seems to be hard finding ae85 specific wiring diagrams for wiring the body plug on the ECU.

The loom is from an AE92 levin, same car that the engine is from. I had it sent down from a wreckers in CHCH back when I started the conversion. It's more the feeding the engine and ECU power and signal from everything it needs which I am uncertain about. I'll just do it step by step and hopefully I'll have some help along the way.

Hey thanks man, Yeah I need some luck by the looks of it, I have the wiring loom for the engine on the floor behind me and I'm looking over it now. What sort of silvia do you have? I use to have a 1996 180sx type x many years ago...ahh I miss that car. Who knows, maybe I'll get my head around it and figure it out. I'll help you if I can but at the moment I would be no use lol.

Hey team First of all the discussion is here: https://oldschool.co.nz/index.php?/topic/58920-steelos-1985-ae85-levin/ So I have had this car for ages (about 11yrs or so), when I got it was a stock 3au powered auto and I drove it around for a while before I took it off the road to begin work to make it something a bit more fun! Work done so far: TRD springs 8kg front and 6kg read with short stroke shocks Smallport 4age with loom and ECU and 22 spline T50. AE86 pedal box AE86 rear end with a TRD LSD. AE86 Fuel tank and lines. Wheels: SSR MKII 14x8 -12 front and 14x9 0 in the rear. Work to be done next: Wiring. Fucking Wiring. lol. Seriously please help me with this! link to discussion above. Here are some pics of the car!

Hi team, I'll post up the build thread and info tonight when I get home from work. In the mean time there a couple of pics in the introduce yourself thread. I wanted to start this discussion off now to ask for some guidance around wiring of the car. I have a smallport 4age sitting in the car ready to be wired up. I have a uncut engine loom for the engine. Where do people recommend I start? I am going to get started on it this Saturday, I need to have a good look at everything and familiarise myself with it again. No doubt I'll have more questions and some pics to follow on from working on it this Saturday. Thanks in advance for any info. Build thread here :
