I did a quick search and didn't see a DIY for the coil pack connector replacement, so I thought I would post one up on here. I am new to this forum and want to be a contributing member here. here is a picture of the part number.

here is a picture of the new connector. Be sure not to push in the white portion of the connector, that is done last in the building of the connector.

I got all three connectors from my local Toyota dealership for 22 bucks total for all of them. That part number 90980-11246 is a Lexus or Toyota part number.

Without further ado, off to the work.

Tools needed are:
1. Metric allen wrench set
2. 12mm deep socket
3. 3 inch extension
4. Ratchet wrench
5. Pliers, regular and needle nose
6. 14mm Combination wrench
7. #3 phillips srewdriver

1. Remove the negative terminal from the battery. (no Picture needed)

2. Remove 4 allen bolts that hold on the timing gear cover

3. (optional) While the engine cover is off, you can take off this bolt and clean the OCV filter. This is not required though. The filter is behind the bolt with the arrow pointing to it.

4. Pull this connector off the throttle body.

5. Loosen these 2 screws on the intake tube marked with red arrow, and remove the hoses indicated by the green arrows.

6. Loosen this nut on the throttle cable, and pull the throttle cable out of the bracket. Remove the throttle cable end out of the throttle body

7. Remove these 5 nuts that are indicated by the red arrows. The two on the bottom are hidden by the wiring harness in the picture, but can easily be seen.

8. Remove the two bolts at the top of the throttle body.

9. Remove this hose off the throttle body.

10. At this time, the throttle body can be moved. I just pulled it out far enough to where i could get to the connector.

11. This is the connector that I am replacing at this time. you can see from the picture, that all that is inside the connector is two female pins. They were able to just float around.

12. I don't have any pics of this, but it is very easy. since there was nothing on the inside of my old connector, the wires just pulled right out. be sure to note which way the wires were placed in the connector, beause they will have to go back the same way. When I did my other ones, there was still some plastic still inside the connector, and all I had to do was take a small screwdriver, and break all the left over pieces out from around the pins.

13. To assemble the new connectors, push in the female pins from the back of the connector until they click into place. Be sure to put them back in the same orientation that they came out. once the pins are in the connector, push in the white piece until it clicks into place. your pins are now secure in the connector. This is what it will look like after.

14. I would suggest replacing the other two while you're in the process, if one broke, the others probably aren't far behind.

15. Installation is the reverse of disassembly.

Hope this DIY may help someone down the road.
