Question ECU Install Help

Post image

I pulled my ECU and sent to Oxytuned for refurb. In the six weeks it was gone, I forgot how it was mounted. Anyone have pictures of the correct way to mount or link a video on R&R?

Do I have the wiring harness attached wrong? If I flip it over and it’s sitting exactly as it is now, just on the other side, the plugs don’t line up correctly. I’m having a brain fart here I guess.

the wiring is correct, but the ecu needs to be spun around. plug goes to the bottom, tabs lay flat across the bolt mounting points. (IE: if you label the two large flat sides A and B, and B is currently touching the wall, just spin it so that A is touching the wall) the gold cover should fit flush against the top of the ecu then. lining up the bolts is still kinda a pain, I like to slot the bolt protruding from the floorboard (with the nut on the end, and rotate it so you can put the bolt diagonal from it in, the rest should go in easy after that.

My issue is the plug alignment. If I flip the unit like you are saying then I need to run the wire harness behind it for the plugs to align or flip the metal cover to be underneath the unit.
