    I am picking up a used RT3 tomorrow that i am installing on a 2003 F250. from looking at the wiring diagram there is a positive connection to the battery and another positive connection (black wire( that is suppose to be to an ignition source. my question is does it matter what battery that i tie into? I have two batteries in my truck? Also where did other people tie into for the fused ignition power source?:

    Ignition power I went in my fuse panel under the dash. On the right side, directly under the hole the tab/latch that holds the cover on has. Went in there and probed a bit with a test light until I found this one (right behind the hole) that comes on with the key.
