I'm looking at installing my LTX-12 before the dyno day. I've had a look at the LTX-12 wiring diagream, so i understand that.. but I dont have one for the 1jz, or have any idea what any of the wires going into the ecu are (except for a couple that are labelled)
can anyone help me out here, either with a link or some information from hands on experience?

I can tell you all the wires we used on VL1JZ. I need to know if your 1JZ computer is the four plug or five plug version. Ours was the five plug (JZA70 version).

it's got 4 plugs in a row leading into it, and 1 wire above those, with a plug on the end.

thanks for that graham.
the ltx-12 can be set up for sequential fire, and I've got the ignition leads to do it.
it seems to me the 1jz has a lot more wires going into it than the aftermarket one could fit... what were all those extras for?

hey Graham, maybe you can answer another wuestion for me.
I know the ltx-12 has an inbuilt boost guage (of sorts). is there any way to attach an external boost guage to the ecu, or should I just run another vacuum line from the engine?
