If it don't look right,it must be inverted , turn it upsides down and see if it looks any better .
Sorry couldn't let that one slip by , carry on, I feel better now!

i know this is probably hard for some of you to believe, but the manual told me that board 5, terminal 14 was the "r" relay on the alternator.  It isn't.  my manual must be outdated.     It is the agreed upon course of action, after consulting with Redbus (we're both enjoying ourselves at Bushnell), that it is probably easier to run a new wire from the alternator "r" terminal, than it will be to find where it may be wired to something in either the front or back wiring area, then find a spare existing, unused wire to go from back to front to dash. 

also, the 5 " area i had picked out is full of ducting, so now i need to build a bracket and mount it beside or on top of the dash.  maybe i can find a bracket at advanced auto or the chrome shop up the road. 

i did get the pulse changed to 17.66 but i didn't have a wire to connect.
