Default IAT to AFM crimp connectors

I bought an IAT with piggy through Braineack from DIYAutotune, but it apparently wasn’t the complete one, it didn’t come with the crimp connectors to go into the AFM female plug. Basically I’ve got the IAT sensor and the plug with two wires running off of it.

Anyone know what size crimp pins I need to connect the two loose wires to the AFM female connections? Is there a better way to go about wiring it up?

Pull the boot back, cut the wires a few inches from the plug, crimp butt splice connectors to the wires and the pigtail. These splices usually come in red, blue, and yellow. Red is 18-22 gage, blue is 14-16, yellow is 10-12. You’ll want the red ones.

Perfect! I don't have a wiring kit (should probably invest in one), but I'll just solder the two together. Looks like I should be looking for a red and a black wire to tap into.

That's it for the AFM then right? I don't think I need to jump the fuel pump like the MS3X, I'm putting in a MS2PNP, (correct me if I'm wrong)

You need to remove the ST fuse in the engine bay and no other wiring is necessary for the fuel pump. Make sure to read the install instructions.
