I bought an 89 gt once and when taking it apart for numerous problems found that the headlight switch was rewired with speaker wire and spliced together with the most effective twisted wire and electrical tape joint. Ditched that project way too many problems and the car was two tone pearl white and bright pink. Hell now that I think about it it had a Ford t-5 with Chevy brass syncos and was filled with gear oil. Just a pos and I ended up parting it out and breaking even.
