ecu repair

[2283kdogg]

so i bought a 93 ka34de manual ecu for 100 like 3 months ago i just checked it now ( should have right as i got it fuck!lol)

and it turns out 2 strips are burned out
when i say strips im referring to the metal lines that go to the each pin

can i just solder them and im good? should i take it to the shop?
are they repairable?

i can take pictures later
fyi i tried the ecu and the burnt out strips are the fuel pump and the check engine light because those didn't work and when i put my auto ecu it all worked

thanks
