Darrell,
I too have a 1949 3100 1/2 ton pickup. When I did my wiring I found it much easier to remove the speedometer, cluster gauge, radio speaker grill etc. and work with these components removed. Pass the wires through the gauge holes. I then worked from the left to the right starting with the headlamp switch, next to the gauge cluster and then the speedometer, re-installing each component of the dash after you have completed all connections. I didn't secure everything tight until I was sure all connections were made including the ignition switch and any accessories added. (ie: cigar lighter, glove box light, radio, etc.) Hope this will be of some help.

Thanks. Are there instructions on this forum somewhere that shows me how to take out the gauge clusters? I think it would definitely be easier to do it that way.
