I have trawled through numerous threads on this subject and have a question. From what I have read, the fundamental problem appears to be that the OEM pins on blocks J, K, X and Y associated with the high current circuits for A/C control, radiator fans, and fuel pumps become loose/oxidized over time and the consequential high resistance connections lead to overheating and burning, with the possibility of solder connections melting, too. Looking at the two commercial solutions, I note that the GT Car Parts product replaces the OEM multi-sheet flexible printed circuit boards with a modern fiberglass equivalent in a single board. This board is substituted for the original flexible PCB. The alternative product from Scuderia Rampante (aka the Helms solution) adds 6 replacement relays to the back of the fuse box, replacing/bypassing 6 OEM relays and provides new fuses for those six circuits, too. This procedure is done to an existing fuse box, with any other necessary repairs carried out at the same time. My question about both products is this: As they don’t appear -- from what I can see in available photos -- to replace the OEM pins and associated female blade plugs with better ones, how do they prevent the fundamental poor contact problem from reoccurring over time?
