I need to know what modifications to make to my 97 ex harness so that everything plugs into my 2000 B18C1 swap and I can get my 1 million mpg's instead of 2 lol. I did a lot of searching and reading and got all kinds of different answers. I just need to know what wires/sensors to add/extend and how. I would greatly appreciate any help. Thank you.

Just lay your harness on the gsr motor and you will see what you need to extend. If your not very familiar with what the plugs look like label them all as your are removing them from your ex motor.

Thanks man. I have the motor in the car already and running on some janky cut up rywire that came with it but need to know exactly what wires to change on the ex harness so i can do it before I put the harness in the car.

Anybody got the straight answers?

Also starting with the thermostat ground is usually your best bet at getting started. Just a tip.

everything should plug n play since the harness and the motor are both obd2
plus the vtec, vtec switch, and the knock are all wired up on your factory 97 ex harness

you will have to wire up the IABS, if you want the black box to work or just run em without the box with one of the the vacuum lines on the intake manifold

But I have to extend the second o2 and the crank sensor too right?
