Hey guys,

My engine wiring harness section that connects to all the coils is in really bad shape. I'm going to try to repair it before I search for a salvaged one, but I'm not sure exactly how to. The wires are cracked in a lot of places, and it seems easy enough to clean and tape up what I can, but the problem area is right outside of the coil connectors.



What do I do about this? Could I just remove the pins with a tool (any recommendations?) and shrink wrap over the bad areas? What about the ones that need new wires spliced in?

I wanted to just buy this

and splice it all in, but it seems to have the same size wires while mine are three different sizes. I don't know where to start! Any advice would be appreciated.

Given your current situation, this is where I would start. Go to an auto junkyard, and buy a similar wiring harness with the same connectors. It does not have to be in good working order. The next step is to take the harness apart, where the connectors attach to the wires. It might be possible to do this without breaking the connector. It might not be possible. This is R&D, no other word for it. It might be necessary to invent a special tool to allow this dis-assembly step, without breaking the plastic connectors. If you are successful, now you will have the ability to take your existing harness apart, and repair it with shrink fit tubing, and new wire, if needed. Is there anything you can do to lower the temperature under the hood?

I don't think the wires being the same size on the aftermarket connector is that big of a concern - it probably was just cheaper to build it using all one gauge of wire. As long as the wires aren't smaller than the original one (they don't look to be from the picture) you shouldn't have any issues.
