hiding engine wires behind the dash questions

Where exactly do you run the main wire. i have the dash out and the heater core box in so i can see where to run them and there doesn't look like there is room anywhere. Also where do you cut the hole to allow the injector harness to run. I assume its right in the middle but i see no spot with the heater box installed.

Here is what i'm looking at.

So no one has hidden the main wire behind the dash, eh? I've seen a couple threads on engine bays and there were tons that had no engine wiring. It was a couple years back so i guess those guys left here.

sweet, thats where i was going to place it for the "test run".

i need some help identifying these wires. i'm doing a 4cyl to 5.0 swap

This is on the main engine harness for the 5.0. I think its the ignition switch, a plug for the soloniod and i don't know what the round plug connects to. I do remember that plug on my 92 but i see no place to plug this into on the other engine harness.


This is the head light harness for the 4 cyl, i took the alternator harness off the 5.0 vehicle but i didn't take the headlight harness. It looks like the same plug from the pic above[square plug]. I don't know what the other plug is. What will happen if i leave them unplugged if this is in fact the ignition harness.


If I can't get help here i'll just post another thread.

Thanks
