I have a wagon that I bought in a non-running state due to a failed engine wiring harness, and a fried dash harness. The rest of the car was perfect and the price was right, so I thought I'd replace the wiring and give it a go.

This project has taken way longer than I had anticipated, and as a result there are a few wiring connections that I apparently failed to document in the removal process, or had been done prior to my purchasing the car that I need help with.

The first couple should be easy the third maybe not so much:

1) From the positive battery terminal there is a small lead that appears to go to the group of connectors mounted on the strut tower. I'm not sure which of the three posts this is supposed to connect to, or even if that is the correct spot for this lead.

2) On the engine harness there is a two wire connector that appears to connect to someplace under the intake. I'm not seeing where that is supposed to go

3) Under the dash looking up to where the fuse box resides there is a group of connectors that mount just to the right of the X30 connection where all the heavy gauge red wires go. There are a series of two prong connectors that all plug into each other and mount on the outside of the fuse/relay box housing. I need to know if there is a specific order to how these are connected together. Also is there any good way to get the center plastic pin to pull out of these connectors so they can be taken off the flange they're mounted to? I've tried every way possible and cannot get these to come out.

I have the w124 manual on CD, but I haven't figured out how to find these specific answers in there.

Thanks,
Dean
