for you with no spark issuse. connect the black with white from the coil to the black with white on the ignitor. also be sure to ground the igniter casing.

Need Help! On the T plug there is no r/blk wire. I do see 2 blk/r wires, is this were I need to put the B+ wire? If so which one do it tap it into?

On the Firewall harness where the STA goes to the blk/w do I also split this and have it go to another blk wire? don't really understand a few of these things all to well.

Please help.

Well figured it out about the +B wire but got stuck on the Blk/org wire. I'm guessing that the Blk/org wire goes to both coil and ignitor blk/w wires? Spoke with Don and he said he did as mentioned earlier.

Swapping a 20V ST in a 1986 AE86 w ST M/T ECU and Harness

All right. The Coil and igniter are giving me some real trouble so let's get this thing pinned down once and for all for everyone's sake. For reference I have numbered from left to right, top to bottom with the top of the plug being where the clip is.

Here is what I have so far and where at lot my confusion comes in.

Igniter Connector

Pin 1 - Black w/ Yellow Trace -> Connects to: ECU 26pin 'N', pin 3 Blk-Y -- IGF
Pin 2 - Black w/ Red dots - > Connects to: ECU 26 pin 'N', pin 22 Blk -- IGT
pin 3 - Black w/ Orange Trace -> Connects to Injector Bundle Black w/ Orange trace, Also spliced in Firewall connector Black w/ Orange trace, run back to coil pin1
Pin 4 - Black w/ Red dots -> Connects to: Check Connector IG -
Pin 5 - Black w/ Red dots -> Connects to: Firewall connector Black w/ red dots, pin 9, plit to coil pin 2

Coil Connector

Pin 1 - Black w/ Orange Trace - Injector Bundle, splice with Firewall connector Black w/ Orange Trace
Pin 2 - Black w/ red dots - Connects to: Igniter pin 5 Black w/ red dots, splice Firewall connector Black w/ red dots, pin 9


From all my time and research I believe that is correct. Can someone please confirm this? Also, I think the Firewall connector splice on pin 5 of the igniter is unecessary and should only need to connect to coil pin 2.

Here's How I believe it works out.

Igniter:

Pin 1 - IGF, 5v to ECU -- Ignition confirmation Signal
Pin 2 - IGT, 5v from ECU -- Ignition Fire Signal
pin 3 - 12V Power from Ignition Switch to power Igniter
pin 4 - Diagnostics Connector
pin 5 - Coil pin 2, Coil Negative to ground through igniter (The Igniter grounds though it's case to the Frame)

Coil

Pin 1 - 12V Power from Ignition Switch to power coil
Pin 2 - Coil negative to ground through igniter pin 5 (Frame)

What does the Firewall connector Black w/ red dots, pin 9 even go to?

Borris.....

This is from another posting on getting a stock tach to work.

Maybe this is the "Black-Red Dots" wire termination in the firewall connector?

That would mean its to the tach in the IP?

ok I know the 5 pin ignitor connector black wire.... thats where I hooked my autometer from. Now, what wire on the cluster will it hook to? thats my question.


Ok I figured out....

Under the gauge there is 2 plugs each of them with a bunch of wires. The cable for the tach signal is on the second plug on the right (there should be 2. The one on the right) and the cable is the very first from left to right. Color is black with red dots.

If you're going to wire up a silver top, take your time. This will get you into the ball park. They are just slightly different enough to be really frustrating. I have been working stubbornly on mine for almost 9 months now. I think I killed my ECU in the process and I am waiting for my parts to arrive to correct that. I have a ton of notes. One tip I can give right off - Keep your 16V harness and build the new harness to match. You might think paying for the cionversion is a little much but at this point I can tell you that it is VERY CHEAP comparatively.

I followed everything you said to do but i can get my car to fire up.

i got 12v to each injector. 12v at the coil and 12v at the ignitor. but NO spark.

pull the wires and nothing spark. I pulled the plug off the dizzy and i got no power to any pins

 Re: (zenkisr5) » Reply  Edit


i had the same problem, turned out to be a faulty coil. tested good, but it seemed the spark was getting lost in the dist.
as for no power to the dist pins, did you test them the way it shows in the FSM? theres a link in the "20v References" thread thats stickied.

i swapped out with another coil, started right up. this thread is great, but with all the color coding, and me making my own harness, alot more research was needed. in the end, this thread proved very helpful for the junction box #4 plug, just had to sit there and write down evey color wire, cross reference with other notes i had.

 Re: (nikos_trd) » Reply  Edit


probably different. the jdm runs off MAP, so the usdm will have AFM wires, some going into J/B#4, so that plug might be different. not sure if the Junction Blocks are the same and on opposite sides, or set up differently. you should try and find a jdm ae86 wiring diagram and/or electrical parrot manual.

I am using an SP Tec Dizzy kit. You should be alright. The only thing that was moved to the front of the engine was the rotor and cap. The distributor and it's connector are still at the back of the head on the exhaust side. You should be able to run the connection from the hole trough the firewall, along the firewall to the connector.

Does anyone know where to connect the White,Black wire to?

Its comes from one side of the RC Filter sitting next to the coil/ignitor. The other side (Black,White) connects to Coil +VE (Black White). I'm think I should earth the White Black?

the Noise Filter, little grey box? one line is from power, other is common ground. i got a pic of the wiring from somewhere. bottom right, the ground is the common sensor ground(E1 iirc)

when does the IGT throws 5v signal? is it while cranking? im not gettin signal from the igniter IGT pin.. please helpp,,

i got 12v going through my igniter and is grounded.

i connected the IGT ECU pin to IGT igniter.

theres voltages going through the COPs and is grounded also. just the IGT pin on COPs not throwing signals.

Do you need the 20v fusebox to do this wiring conversion? The one under the hood? Thats the only part on my harness that was cut and not included.

theres only one under dash harness i know of. it goes from the pass. side junction box/COR/and a few other things-to the cluster and drivers side junction box. some of the wires on the yellow ae86 16v ecu plug go thru the under dash.

Kewl, when you said under the dash, I didnt visualize it coming from the passenger side. This is the harness your talking about correct? I knew this one was there but didn't know that was the one you were talking about !!!
