1jz help... 3-pin grey round plug (BLK/RED wires)

[GeneStarWindGSW]

I have an 89 mx83 and i need help wiring my 1jz-gte.
ok so this plug is on the 7m-ge engine wiring harness to the mx83 body harness.


And in 91-92 model it looks more like this:

This is very simple the 2 fatter ones (they have continuity to each other) power the injectors and coil(s). Wire the coil(s),igniter, and ignition dampener power to one and all the injectors to the other. On both they are usually the black/oragne wires. The third wire (smaller one) powers 02 and iacv and basically everything alse in there that needs power. Depending on your harness that stuff is usually on a blk/red wire.

goes into this


Then when i bought my mx83, it came with a 2jz-ge swap and they spliced and wired this connector to the 2jz-ge engine wiring harness, but i don't know exactly where. (Could get a photo if that helps)

Now that i have my 1jz in my cressida, i cut this plug off the old 2jz-ge engine wiring harness and i'm trying to find where exactly to splice it into my harness (the actual wires).

i'm thinking where the EA2 connector is (Fusebox connector for ma70) is where im suppose to give power for all the wires but im not 100%. In the guide above it says to give it power but im still



If anyone could help, I'd greatly appreciate it.

if you have a jza70 harness all you need to change is the 22 pin plug and the big square grey one under the dash a bit, but thats for a manual. i think for the auto you need more work on it, butpower for coils and o2 sensor is located on that square plug and i actually think you don't need to change it. ill have a look when i get home its been a while since i did it. ih1 is for the fusebox on the jza70 and you don't need to plug it anywhere.

alright cool, let me know about that.

I posted up another pic and fixed some names of the connectors.
