Hi, I put a wb02 unit in my rear boot near the ECU and I was wondering if anyone can tell me an easy way to perhaps piggy back 12v's off the ECU maybe? Or do I need to run a new relay from the engine bay? Any info or links to how it can be done would be appreciated. I'm sure people need to do it all the time but I can't find info on how (in an aw11 anyway), thanks.

Found this

Is that the fuse box in the engine bay? I couldn't see any wires in mine, just fuses.

So on the ecu there is a wire supplying the voltage? If anyone knows which one ? I just found this page ECU 1990-91 Japan 4A-GZE AE92

Is it the Circuit opening relay G-R FC that i need to use?
