i know its a dumb question...but just want to clarify something..when doing the engine wiriring on a swap, and you are supposed to put wires into pin locations, do i just splice into the wire that is already in the conncetion, or do i have to take out the old wire and out in a new wire?....thanks

 

I guess that all depends on how nice of a job you want. It will either look all hacked up, or it will look factory. I like the factory look. But if you know what you are doing you can do some hacks that don't look like ***. All depends on how you want to do it IMO.
