OK
it looks like you have an auto soarer ecu, then maybe a chaser 1jz engine set. if that is the case then your gonna have to get another ecu or maybe your harness got cut, did it get cut anywhere?

In those cars the other plug goes to the dash. So you need to find the missing ECU plug from another donor car/harness.

well this motor is in my s13 not a yota so do i need those clips to have the car run? or its that ONLY for dash and such. im just worried it has igintion and power in to other harness.

Yes, you will most likely need them. There are a few power/grounds there that need to be used and also the Main relay switch.

Wow you guys don't know much about the jzx90 do you?

This is the right ecu for that engine and harness. Wiring it into s13 is super easy.

Don't waste any money dude you're on the right track. The ecu you have is much more reliable than a70 ecu trust me.

I can make you a harness if you're interested. As for the body connector you can just make your own if you really want to. Or I can make that also no biggie.

Btw, This is Aphxero posting from my brother's house oops.
