I am trying to install Foglights from a 96 gas truck onto a 95 Cummins truck I swithched the bumpers and found the plug for the fog light wiring no problem but, I can not find the plug in the dash for the switch. The only plug I can find is white flat plug. The switch used a gray plug shaped just like the one for the O. D. in the 96 truck. Is there an adapter available?
