My hemi efi project is finally getting close. It will be run on the builder's engine dyno. Holley dominator ecu, smart coils, ev1 style injectors .And all of the sensors. I'm assuming most is metri pack, connectors. The harnesses will be run long on the dyno. I will need to shorten to required lengths once in the car. I am looking for a quality terminal kit and quality crimpers. I have the pin removal tool kit. Any suggestions are appreciated

First check out the Holley wiring store. They have connectors, pins, crimpers, etc. If you can't find what you need there then search Amazon (or Google) for Metripak kits and crimpers.

Not all of the connectors are Metripak, Holley uses mostly GM components and GM uses whatever fits, works and is cheap. So you'll find all sorts of weird stuff in a Holley EFI harness.

Thanks Andy. It does look like some of the gm stuff is weatherpack also.

The MAP sensor is usually a weatherpak for some unknown reason. It is a complete bag of stuff on GM engines. Ford and Chrysler engines can be even more weird.

Automotive plugs can be made from various manufactures. Some will have a # and the manufacture name and you can look it up that way. As you see here you have to kind of know what you are searching for.

Look here or some connector products....

This is who I use for my connector parts.

They list the sensor and the parts needed to connect to it. All quality stuff

If you know the GM part number you can search that way, or the aftermarket part number, usually.

Same the injectors or just about any other EFI part

Appreciate the information. The you tube video was helpful.
