Here's the scoop, I've got a 2000 gsr swap and a 96 civic dx.

What wire harness do i need to make this happen? I've read that I need a 96-98 ex wire harness and that will work.

I've also got an OBD1 p72, can I use that ecu and just use a jumper harness to hook it up? And if so will that throw a CEL?

I've read that few different things about the motor mounts... I have a complete set of gsr mounts and a complete set of the mounts that are already on the civic. I know I need a few from a si but which ones?

I have tired searching and these are pretty much the questions I still have remaining.

 

you need the T bracket from the Si that goes to the rear mount

 

as for mounts from the integra.. the only ones you can use are the front transmission bracket and the a/c bracket (if you're not keeping your factory a/c). you need an si t-bracket, and si timing belt post. upper transmission bracket you can just reuse from your d series, along with all the rubber mounts.

96-98 ex harness will work, but you will have to add a wire for the iab's if you're using them. also get a connector for the iat. little bit of extending of some wires is necessary. you could use your stock harness if you wanted to, but you'd have to do some rewiring.
