im currently trying to install a haltech that i purchased with a plug and play harness. now what i don't wanna do is rip apart the dash to get to the damn harness for the ignition coils. could i simply run the wires from the engine harness hole all the way around the engine bay or no? also, my other question is this. i want to at least retain the usage of my lights, and windshield wipers.ac and heating are oblivious to me as in Atlanta we don't get much snow or even below freezing temperatures, and my daily work routing is to work inside a dairy cooler. this is a constant 35 degrees and im able to handle this for extended periods of time in a tee shirt and jeans.

so my question is this. can i remove a portion of the harness and wire in a new wires?

Are you asking the same question MikeD is asking about those "few wires"?

And the other post about the S5 harness? Are you guys together?

no. what i want to know is this.

to get my haltech to work with my car and still retain whipers, and headlights ( and possibly ac) how would one do this? is there an easy way to wire this up manually? like completly cut and hack away at the harness and just run the new wires to have only these opperate or is this out of the question on the s5's? i know on the s4's, there are a numbe rof wires that gat bundled with the harness, but dont necessarilly do anything.

Ah, ok, i understand, the wiper wires run along the engine harness so you have to splice them out of it in order to retain them, that means tearing apart the harness to take out the wiper wires, they get power from the vehicle harness which are the few big plugs also spliced onto that harness that hook up right there next to the kick panel on the passenger side.

Also the stock coolant level gauge gets its signal from a wire that comes in that harness as well, its a green wire with a white stripe that connects directly to the sender, then goes into one of the big white connectors to go to the dash.

The AC request and AC switch functions are an ECU function which either need to be kept, which means taking up the aux. input and a PWM, or, i believe that a relay can be installed using those 2 wires in order to keep the AC working.

Finally, the coil wires come into the cabin via the driver side harness which in term goes to the ECU for that, you have 2 choices, wire them up sending the corresponding wires along with the new Haltech engine harness, or wire them at the ECU location splicing them to that OEM harness, i think both are basically amount of work required to do it, so its your choice.
