I did a LQ9/4L60E swap in my 1999 C1500 OBS. I have my water temp, oil pressure and voltmeter gauges working. I just need my speedometer, tach and fuel gauge to work now. I have downloaded and printed all the wiring diagrams/connector end views from lt1swap.com and some from All Data. Im using a new standalone wiring harness and it has a lead for tachometer signal output and a lead for the vehicle speed signal. Where should I connect the wires coming from my new LS harness to the existing wires to get power to my gauges? I see several Pins on the 4 VCM Connectors that say Vehicle Speed Output. Also I have a diagram for the C100 connector that goes into the firewall on the drivers side. Does the tach get its signal from here? Looks like it will be a white wire, either connector B2 or E8? Lastly theres the fuel gauge. If anyone can give me some help on where I should start I would greatly appreciate it. Thanks!
