There are following wires for the 4A-GZE Igniter

IGt -
IGd (AE101 IGa)
IGf
TAC
IG1
IG2
+B

On the 7M-GTE Igniter, use the following wires and connect as indicated below, to the 4A-GZE AE92 and AE101 OEM ECU.

IGf (LG-B) = IGf (To EFI)
IGt (LG) = IGt (To EFI)
IGda (L-B) = IGd (AE101 IGa ) (To EFI)
IGdb (L-W) = not used
IG1 (L-R) = G1 (Coil 1 Trigger)
IG2 (L-Y) = G2 (Coil 2 Trigger)
IG3 (Y) = not used
+B (B-O) = +B (Coil Common)
IG- (B) = TAC (Tachometer & Diagnosis Connector)

Ok I found this.. but this doesn't help me out a whole lot... mainly because I have nooooo clue what wire is the IGt - or IGd or IGf etc etc... Soooooooooooo if anyone would like to explain or let me know the wire colors that would be awesome. I noticed in the GZE harness there was 2 Black with Orange 1 Black with Red 1 Black and 1 Black with white. I think the only one I know is the TAC which is for the tachometer. The small 2 pin plug looked like it had 2 black wires.

I'll attempt to get the connector with the 7mgte ignitor as well... but we'll see. Since I can not seem to source the OEM ignitor for the 4agze since I have the DLI and MAP version.

also found this as well... so I'm guessing I'll have to use IG2 for Coil 1 Trigger and IG3 for Coil 2 Trigger. Taka Aono sent me a message back and He said that you just have to change 2 wires, but lost his diagram with what went to what.

Here's a great reference page from C4AG.

Looks pretty straight forward. Where are you confused?

hahahahahaha well... I wrote down the PIN numbers what color and what they went to.... when I was going through everything making sure that THIS WIRE went to THAT SPOT haha. son of a..... hahahahaha thought I wrote all of it down. guess not. well chalk that up for a fail on my part!

I knew the link at first I wondered... wth is he posting this for? then i looked again. oh hey look there's the IGt IGd blah blah blah. I'll post a picture of my "Box diagram" LOL *facepalm hardcore* well thanks for that Dr. Occa. I guess I've looked at one to many wires lately.

Yeah, not only do wires get crossed, sometimes eyes do too.

Seriously though, if you still need a second set of eyes let me know.

Werd! I think I found a 7mgte for $40.... so we'll see

So you have a second pair of eyes? If you could overnight ship those that would be awesome hahaha

Here's a picture I threw together to help better illustrate what you're working with. If the wire colors don't line up with the numbering scheme then it's the mirror view.

You sir are he man! Thanks for the diagram! Every little bit helps

That's kinda funny those wire colors on the coil you have don't match what I have lol

following your same picture diagram and numbers... this is what I have. so my question is... are the pins still the same inside? the part number I have is toyota #: 89620-14446 denso #: 13160-1063


6 pin.

1. looks faded brown
2. Blue
3. Black
4. Yellow
5. empty
6. Green

4 pin.

1. pink
2. gray
3. white
4. faded brown

the wire colors you have are from a 89621-30020 ignitor from a Supra 1997.09-1998.08 the ignitor I have is an older version? from a 92 supra which I did not get a connector with it... oh joy! this just another funtastic piece to do.... fml *facepalm*


edit: I think I finally found it!

purpose / designation / color on igniter / color on wiring loom
signal, igniter -> ecu:/ IGt - / RED / black
signal, ecu -> igniter:/ IGf / GREY / black&yellow
IGd (AE101 IGa) / WHITE /black&orange
battery:/ +B / BROWN / black&orange bigger
tacho:/ TAC / YELLOW / black

coil1:/ IG1 / BLUE / black&blue
coil2:/ IG2 / BLACK / black

cleaned up so it's easier to read..

Alright so I'm not getting spark from what I could see....but I also had someone who was scared to hold the key in the start position..... so we'll see tomorrow.

So I have no spark on any cylinder. Igniter is getting power coils getting power but not getting a signal. So I've narrowed it down to the IGt IGd IGDa or IG1 IG2 on the CAS..... anyone know of some testing procedures. Oh and the igniter is grounded as well

OK I have power all the way up to the coil packs. Just seems like they won't discharge.
