The AMP Superseal connector is slowly taking over as the default connector for ECUs and other motorsport devices. Easy to use and high pin counts make it an obvious choice.
There are 2 sizes, 34 and 26 contacts and 2 keyway variations of each. Some ECUs such as the ECUMaster Pro16 and the Motec M1 use all four variants.
There are 3 contact sizes to take a variety of wire sizes. Be careful here, the contact / connectors are rated at maximum of 15 amps. Be aware of this when using them on PDMs.
Part number | Wire Size | Insulation diameter | AWG |

We have always used the 3-1447221-3 This can go down to 24awg folded over, takes 22awg no problem and can go to 20awg. You really have to question why you would want to go larger when its all signals and control on an ECU.
