    Ecm pin size

    looking to build a flex fuel harness. What size pins do we need to pin the ecm? I know it's a square head shape

    Common GM size E38 E92 type ecms

    I found 12-14 gauge, 16-18 and 20-22. If I had to guess I would think 16-18

    Honestly, the easy way is buy a junk harness or connector cores, harvest the pins to be used in other projects.

    Lol, that's exactly what I did. I had an old harness laying around and it was sacrificed.....I then found a set of pins I had laying around 5 minutes later
