ARNAV 21 Install Manual?
 

Hi there,
I'm going to be replacing an ARNAV 21 Loran with a Garmin GPS400 on a friend's Mooney. But I don't have the install manual for the Loran. I want reuse the wiring that is interfaced to the HSI. Does anyone know where I can get the pin-outs of this Loran? Thanks for your help
