Id like to replace the main big brown 16 pin connector on my 06 WRX harness. I found the Deutsch connectors but unsure what size deutsch crimper to get or connector for the wires. Please can you advise. Gutted I'm 5000 miles away from your workhop where Bucky goes.
Sometimes the connector itself may be male, but the electrical contacts within it are female. That's my best guess, at least, I've used male/female my entire life.
