I got my mf u out and it an AMR 5360. I have an AMR 1280 I was going to try in my disco. Supposedly the 1280 came out of a 97. anyone know what the different MFUs are about? I haven't tried the MFU test because I dont want to fire up my disco inside my shop and its not yet ready to go outside. I'll no doubt try the test asap....
