1JZ EUC wiring diagram Mon, 19 September 2005 01:20 Go to next message
hey guys... the old 1JZ is now bolted into the 180 and im now trying to wire the 180's power supply into the toyota ECU.... i've heard powering the ECU helps it work Wink does anyone have a wiring diagram for the 1JZ ecu, so i can do this without sparks.

cheers
Greg

for those interested in the build so far ...

hmm, how do i find this out.... this engine came out of an MZ20 soarer, which came out of something else?? will it be stamped on the ecu, or should i be looking for serial numbers?

Part number on the ECU will be the best way to tell.

if you just give me your e-mail addy I can shoot the diagrams off to you,and you can see if they're useful. number of plugs and size of plugs is also a helpful identifier

I'd say it is for a supra cause the diagram is from the supra forums, i did find this over at soarer central however.

They are on that diagram, the switched power ones are the ones through the main relay, there there is ignition, and there is constant power (BATT).
