The computer plugs into the harness which merely plugs into the engine. There are 3 grounds that need to be made. One is next to the computer. One is off the injector harness. The last is at the end of the harness(next to the starter relay on 5.0's). The 12V source for the harness is also made at the end of the harness(at the starter relay on 5.0's). I believe there are 4 of those total. That harness gets its power separate from the chassis harness. They plug in at the same location but they are not connected to each other there. His car, as well as yours, has a starter relay on the fenderwell also that allows you to get your 12 volt source. As for turning the fuel pump on, simply run wires from the relay to the pump.<br /><br />The only thing an aftermarket harness would even offer is the same harness as a stock car minus the emissions connections. What else are you referring to that you think I am missing?<br /> <br /> <small>[ October 11, 2008, 10:18 PM: Message edited by: 514 Mullet ]</small> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>BlowN67</b> <br /><small>Member # 4229</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2008,9,11,22,53,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> you could be right maybe i just did it the hard way. <img border="0" title="" alt="[Big Grin]" src="biggrin.gif" /> <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
