How to Replace Install Subaru Ignition Coil Connectors

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

For this one the connector is actually broken and it's loose. It just slides right off. That can happen. They get old and brittle. If you've got broken coil pack connectors and they're loose, they can be vibrating back and forth, could end up with misfire, and you don't want that.

To replace the connector for the coil pack, you need to remove this yellow lock. You can use a small flat-bladed screwdriver and just gently pry it up. At the same time, you don't want the lock to go flying out of the way. If the whole connector breaks, that's fine. They're very brittle. The only thing we want to reuse is this yellow lock. I just want to put that aside in a safe place so I can reuse it. I want to keep these wires in order.

They pretty much go in order, so it's red, black and white. There is a small lock and a black lock right here on each one of them. I'm going to take a small pick and very carefully pry down on the lock and you can almost break it off. Because this connector is so brittle it doesn't really matter, we're not reusing it. They just get brittle with age and heat cycles. I'm going to carefully pull these out. That red one is loose. I don't think these ones are loose yet. Get that out of there. I'm just breaking the locks right out. You do want to be careful of the metal connectors because we want to reuse those. Once those locks are open they'll come right out, and they kind of stay in order anyways.

Here's our new connector. It has a new lock. That's was what was originally broken and then we broke the rest of the locks taking this out. These are in order. The orientation was this way, with the lock to this side. Put them in the same way and push them into place. They'll all kind of make a small little click as they lock into place. So the locks are in there. They're not moving, but we need to put the yellow lock back in.

Take the yellow lock and slide it in place. That wire part goes toward the bottom, and the top part that sort of matches where the terminals are goes on the top, and just push it in. You'll just feel it kind of slide in place and it'll lock nice. It's flush and that's perfect. Now this can go back on the coil. It'll slide right into place. It'll click when it locks in place. Now it won't come off.
