Engine Swap Wiring: I need suggestions!, Wiring Gurus please have a look Options

[Dr_Tweak]

Hey everyone,

I'm in the middle of an engine swap right now and I'm getting kind of confused. I understand that I need to strip out all of the engine related stuff from the recipient car's harness, which I've mostly done. All of the wires that ran from the ecu down the harness I've pulled/cut out. The thing is, a lot of wires ran from some of the body plugs to the ecu, and I cut those. Here is what's left of the harness at the interior end, you can see these 5 plugs that go into the locations in pic 2.

PIC 1


And this is where those 5 plugs go:

PIC 2


Now, here's the engine bay end of the harness, which shows the plugs that go to the fusebox, the positive battery cable, etc.

PIC 3


Here is the new engine's harness at the ECU end, I have not stripped anything out of this yet. You can see the two plugs on the left have been cut, all of these wires went into the dash on the donor car. The two plugs on the right go down the wiring harness, and there's another plug off to the right that plugs under the dash.

PIC 4


Now, am I right in thinking that I have to find homes for all of the wires in PIC 4 on the left that have been cut? Will those wires go to the wires that I see in PIC 1? And how do I go about putting these harnesses together?

Thanks a lot for the help
