HEI in Mopar ECU casing

another problem i am going to have, the 4 lugs that i need to solder the wires too, there is barely any metal exposed to solder to, The plastic things that hold them in place come all the way to the top of them, and the plastic is hard as concrete..I just dont think there is enough metal exposed to get a good solder joint to the wires..


The pics earlier in this post where someone did this had about half the metal lugs exposed so there was a lot to solder to and even shrinkwrap!
