OK finished up the alarm today and it works as advertised waiting for the dome timer delay and I finally got the washer bottle installed (well I did not do it but it's in) and the wipers work but the motor for the water pressure is not.
 
I tested the wiring and the motor prior to having it installed and it worked fine.  The wiper motor is working fine and I see one fuse and Is this for both the wiper motor and washer pump motor. I realize the wiper motor would be a larger circuit but so not see a separate fuse or where the wiper motor is powered. The fuse box looks OK as far as good fuses.
 
You get 1 thing working then its the other, but I know the wiring was working fine as I had tested prior to installation.  Any info would be greatly appreciated, still researching this. Thanks BB78Confused

It all worked prior to getting the bottle re-installed into the impossible corner but  since I got the car back no working motor. Checked the wiper motor and fuse and it all worked when I connected prior to the bottle for installation.  So if I can get the harness off at the pump(anyone have 1/2inch thick arms that can bend 360 degrees and are 48 inches long)  or a rachet extender that bends several different directions and then can attach it onto the plastic nut you cannot see and remove to get the motor out....then try the reverse to get the motor re-installed.....what were the engineers thinking????

OK got the pump working. As stated The wire was good and the pump ws good, but somehow the connector needed a little cleaning to make contact. Presto and now The pump works fine.  I know you all know this but there is a panel inside the wheel well that provides access to the bottle(but mine was epoxied shut) but you can reach in the open scoop and your right at the pump and the wire.... I know you all knew this but  my first vette I had no clue it was in reach, never tired it??? Now on to the cruise control...bringing it back alive from the swamps.....Hug
