If you live in the LA area, you have PI, Wilkinson, and Byers to choose from.  Hall no longer works on the P.  Lance Nist is an electrical genius but is also no longer working on cars either.  If it were me, I would CALL PI and discuss the problem with them and seek their response.  It sounds like the car went to them with electrical issues and their work may of disturbed something else (which is where I suggested you start looking at the beginning) not to mention they wired a fan to always run which is NOT correct.  If you no longer want to engage PI, then I would go to one of the other two, but both are probably backed up for months but you would need to call each and discuss the problem.  The LAST thing I would do is to take it to someone unfamiliar with the P and its unique wiring, unless you have a good referral and a shop that works on exotics.  V's performance in Orange does a lot of GT40 builds, etc.  They may be willing to get involved.  Unless you are very skilled at auto electrical systems, trying to diagnose this further is akin to asking a dentist to pull a tooth over the phone.  Shop rates are at least $100 an hour and it sounds like you are into it for a grand plus whatever parts may now be toasted.
