Attach Harness before or after you put the motor in?

[queenskid926]

Which way is easier? time consuming? To attach the wire harness before or after you drop the motor in?

I always find it easier to attach it before if I have the intake manifold on the head, you can always put it through the firewall after. If you are piecing it togeather once you have the longblock in then you could go either way.

I've always done it before the motor goes in.

^^ Same here. When you pull it out of the car, it's an excellent opportunity to inspect the harness as well.

The difference is huge! Do it out of the car as said. I did mine out of the car, then had to swap it while in the car. Now I have to swap it again this weekend for a Good one. Much easier out of the car!

Attach the harness to the motor, coil it up on top of the intake and drop it in.

There's no way in hell you want to try to reach all the sensors, etc with the motor in the car...

^good to know since im about to throw mine back in with a newer wire harness

Before!!!! It's a no brainer. It's soooo much easier than the other way and once you get the motor in just connect your grounds and plug it into the ecu.

the small wire on the starter is much easier to get to with the engine out of the car. Much swearing/wrench throwing occurred when i tried to install a new harness with the engine in the car.
