"Soldering the wires from the new harness to the engine's harness is a PITA! Make sure you use quality heat shrink on each conductor. Trust us, you need to PERMANENTLY fix the wires. We all thought we could 'rig' the connection but only to fail a couple hours/days later!!!! (and you do NOT want to be in the middle of town throwing a code and misfiring!!!)"

My solution, albeit temporary until the new connectors arrive from Amazon, was to disassemble the connector and remove the pins, then crimp and solder each pin onto its wire, and then reinsert the pins into the connector and snap it back into place. And you're sure right: major PITA. And it didn't help that it was cold and pretty dark.

It's a lesson about carelessness and the delicacy of these connections that I doubt I'll have to relearn.

Hey LS430inDe, I read that entire thread, and there wasn't any mention of having to reattach the wires to the spark plug connector.

 

"Your post also said: "I plan to visit the junk yard, cut off the #1 plug connector" ... which is not the one closest to the driver. I'll take some pics of # 7 coil on plug connector and post in a few minutes."

That's because I wrote that before I knew what the heck I was talking about. At that point all I knew for sure was that it was the plug closest to the driver seat, which I have since learned is #7.

And super thanks for snapping the photo for me. It's good to have confirmation that the wires are connected correctly.

 

This may be more than "temporary," wordwrkr. Others have tried "Rube Goldberg" type solutions that proved to be temporary. Your direct pin/wire crimp and solder is akin to a solid factory connection. Nice work.

 

Thanks, Tom. The hardest part was figuring out how to get the pins out of the connector in the first place, and not dropping and losing them. Cold fingers make for lots of fumbles, and it's freakin' freezing cold here in Kansas City!

 

It's there now!

 

Sorry to bring up an old thread. I’m wondering same thing happened to me when replacing my starter. If I’m looking at the engine standing over it. It’s the right one in the very back. So the coil plug closest to the driver seat.

I need to know the order they go in
