Toyota Repair: 1991 land cruiser EFI relay, land cruiser, fuse

Question
I have  a 91 land cruiser with the chronic  relay overheating problem I have found many blogs about increasing the wire size from the EFI fuse to efi relay. I've also read that is just a temporary fix. Do you know if Toyota has ever come up with a standard fix for the problem?

Answer
Toyota had not come up with a fix for this, I really don't have a solution as well, I have seen a couple where the relay was loose in the socket and tightened the connections until the relay fit in tight, using a heavier wire may help but the real problem is usually that the relay connectins overheat because it's not tight causing excessive resistance and the overheating.
