for a 5g civic it takes mad wiring, u cant just repin it unless u have a 6g civic. u have to get the integra harness and solder it to the civic wires. i did it and it was worth it. as far as fittin, i kept the gsr plastic on there, just trim the cluster a bit and then folded the plastic bakk to make it fit. then i zip tie em to the car. looks clean to me. there is just a small gap on the bottom but u cant c it unless u lean over. ill post pics soon.
