just a few questions about wiring

Thanks Player1up, I haven't cut anything as of yet. I think I have it figured out and hope to start this weekend. I'm going to keep the PDC as well. My buddy found me the OBDII connector at pull a parts today. Also got me a battery temp sensor. Looks like most of the wires going through the firewall will not be needed.
I'll let you know how it turns out,
Tom
