Guys,

I'm installing a 1jz Dr Tweak harness into an SC300 and have run into an issue... maybe I'm just missing something but I do not see the 3 plugs for the ignition module on the Dr Tweak harness. Anyone else run into this?

 

post pictures of the harness or any unplugged plugs

 

I haven't started installing the new harness. It looks just like the one on Dr Tweaks website. When I go back out to work on it tomorrow I will snap some pictures. I have traced the harness out and after the injector plugs there's only a couple of plugs left - none even remotely similar to the ignition module plugs.

 

mine from dr. tweak was plug and play except for the tach issue...

 

 

I went outside and snapped that of the harness.

 

Picture is a bit hard to tell but im assuming its these plugs. Can you take better pics of the plugs whenever you can.

Could they have given me the 7M plugs or something instead of the 2jz?

 

The connectors in your last pic are for the fusebox and a/c compressor.

The PPS will be in the correct location.

Let us know if you have any other questions. How do you like the looming on your harness?

@Dr. Tweak are you saying the ignitor will be sitting inside the car?

 

^^^ Yes it does!

 

my harness was done by tweakd too and my ignitor sat near the driver side strut mount why is his inside the car?

 

Does anyone know if the OBDI diagnostic port is supposed to come with it? Or is that no longer used?

 

No longer used. Most people don't need that to diagnose stuff which makes it clutter.

 

Glad you got it figured out. Did you contact Tweak before posting this? Might have got a quicker answer.
