Three connectors on my engine harness are cracked, I have a spare that still has most of its connectrors intact. I just wanted to know if I could cut and solder them up to the harness that I'm using now without any problems. Thanks in advance.

 

Dont cut and solder, just remove the pins and put them in the non-broken plugs.

 

yes you can solder them but it will take hours and days to do that. I would just repin them.
