What type of terminal pins do radio harnesses use?

Motor Vehicle Maintenance & Repair Asked by Jdubs on August 20, 2021

Brief backstory: I got a car that was a great deal and the radio is the only thing wrong with it. They told me that while they were swapping out the OEM radio it wouldn’t accept the new one and then when they went back to OEM it didn’t work either. After close inspection it appears that someone was aggressive with the plug on the car’s side and the pins were removed out the back of the radio. I was able to insert 3/5 back in no problem, but 2 of them the wires escaped the pin instead of the pin escaping the harness when it was tugged, so the original pins are worthless.

Question: What type of pins do I need to buy to replace these? The only ones I’m able to find reliably online is Dupont 2.54mm ones. Would those fit?

I have a terminal crimper that I bought for another project and I believe it can crimp these as well. It’s a 2015 Honda Accord EX. I would like to buy multiple types of pins for other projects and making my own harnesses I just need to make sure this one is right on the first try to avoid double 18 day shipping.

Obviously I could go to a junkyard and get another harness, but I appreciate things being and looking stock and a new harness would require pulling 2 pins from that and soldering it instead of just crimping what’s already there and inserting it like brand new.

One Answer

Most pins will have a small tag that buts against a ridge in the plastic case.

Find that and adjust it.
