On my lastest project, a 1966, the headlight harness wire leads on the drivers horn, drivers park light and H/L don't seem to be long enough no matter which company purchased from...... Lectric Limited or M & H Electric. Have used H/L harnesses from both companies. After plugging in drivers side H/L harness extension and park light not enough lead to reach the drivers side horn. Anyone come across this....what did you do to resolve?
