Alright, I have the wiring harness separated out of the vehicle harness. I have a question about the fuel system. The diagram shows a high/low relay for the fuel pump. I assume this is to kick in when boosting. My question is, is there anything special about the pump? What flow rate is the stock pump? It's not bad just 23 wires or so to hook up to make it run. The EEC-IV systems are a little easier at 8 or 9 wires, but the 5.4SC should make the 56 run. I'm planning on running a 3:55 ratio rear end and around a 26" diameter wheel/tire. This just based on gearing should turn out to be 160 + mph. I'm betting on 150 before modifications.
