i have a 01' civic LX and i want to get the speedometer out of the holding house and put in a 03'-05' civic speedometer (the 03' speedometer is beter, it shows better light and is completely electronic.) I tried to put it in it has the same mounts and everything and the harness seems to be the same but the new speedometer doesnt work. I was wondering if anyone has some advice for me. Thanks.
