Hello again, I have progressed in my engine removal journey and there’s a step in the shop manual that says I need to disconnect the wire harness from the ecu etc. and presumably pull it through the firewall which would require dismantling the interior which I don’t want to do. Anybody who’s pulled the engine before is there a simpler way to disconnect the wire harness from the engine so it can come out without me needing to pull apart the wires in the interior, or is this a requirement?
Disconnecting wire harness from interior to remove engine?

Hi
The complication is dealing with the grounding strap and the tvis connectors, knock sensor, and the like that are on The back of the block and intake manifold.
If you can disconnect those while the engine is in the car, as well as the fuel injectors and everything else in that area, then you should be able to leave the harness in the car. Those connectors are the hardest ones to get to and why a lot of people will follow the BGB and disconnect the wiring from the ECU and fish that out through the firewall.

I see, thank you for the response. I guess I have to steel my nerves to pull apart the interior lol, i really dont want to damage it since its very clean

You shouldn't have to get too far into it. If you pull the glove box and pull back the carpet at the center console in order to get at everything you need to.

You might even be able to skip removing the glove box. The plugs are just behind the carpet and it's not very far to where it goes through the firewall.

If I'm remembering correctly, there's something with the AC behind the glovebox that gets in the way. I think it's the amplifier.

oh, and when you put the engine back in the car, don't forget to re-attach the ground strap. It's an alltrac.net special to neglect it and wonder why the ECU isn't getting any power.
I, myself am guilty of it as recently as last month. It is how the ECU and inevitably all of the sensors and the coil get grounded.

Oh trust me I’ll forget about it and you will definitely see a post about it in the future lmao, but thank you in advance for the heads up
