Ive got some electrical gremlins in my 67 Barracuda, bulkhead connector in pretty rough shape, lots of splices and plugs missing. Left blinker only blinks about twice a min and the right about 1000 times a min and when I push the brake the left turn signal comes on. And the positive batt. terminal got so hot while trying to figure it out that it blistered me when I touched it! Im looking at a Ron Francis kit that is a 12 circut but he suggested a 21 circut kit for another 200 dollars. it only has a 6 circut fuse box now and I only intend to add ac and electric fuel pump so wouldnt the 12 still leave me 4 extra circuts? Was just wondering if the 12 is enough or I should spend twice as much for the 21 and why. Any suggestions or advice would be greatly appreciated. Thanks, Clay
