1jz dash harness plugs?

[mk3 bamf]

I was looking at my 1j's harness and are these the dash plugs you have to wire up in to the dash harness? Or are there more? And looking at my ECU I can't tell if it came out of a supra or a soarer, can anyone tell?

doesn't look like a soarer 1j, might be a supra 1j from looking at the ecu but where is your oil sump located at? front or towards the rear?

supra jza70

yeah from the plugs pictured it looks like a jza70, another way you can tell is if it came with a mechanical fan.

That IS the jza70 motor/ecu /harness.
Soarer ones have orange plugs on the harness for the body ones and have 4 row pins on the ecu plugs.

Awesome.
Thanks guys. I really appreciate the input.

Are these the plugs I have to wire into my 89,MA70 dash harness? Or are there more?

And also, can anyone post a couple links to diagrams and how to splice the harnesses together? I don't plan on extending it. I'm drilling a hole below where the speedometer comes through the fire-wall.

My 89 MA70 was an auto will that make the wiring end of this swap my difficult?

those are the harness plugs, and being an auto wont make it more difficult to swap it (i assume you're going 5spd now?) If so you will just have more wires left over (the wires going to the Trans ecu)

The supra has already been swap to 5-speed, but I need some help with what wires go to what pin out on the plugs.

If some one could give me some links it would awesome.

Thanks for the link Tissimo I appreciate.

 

[mk3 bamf]

How about links to a right up on what wires need to be solder to what wires.

I'm still confused:aigo:

 

[mk3 bamf]

Looking at these connector mappings it's saying MA71, not MA70 whats with that?

 

[tissimo]

its the same, dont worry..

 

[mk3 bamf]

I'm pretty sure that I've got this down now it shouldn't be hard at all.

Will the fan computer connector, plug in to the MA70 fan computer connector plug?

the hydrofan ecu connector is the same as a ma70 body connector,yes

mk3 bmf pm me, i have some diagrams if you need them its on .PDF form. lmk

 

[mk3 bamf]

Oh dam it, I thought that the plug with the blue wires was for the heater fan.

But it's for the hydrofan so I don't have to worry about it then.

Can I just take out the wires from the harness that go to this plug because I'm eliminating to hydrofan?

Thanks in advance,
Scott
