1998 Dodge Ram Pickup 2500 5.9 diesel, 5 speed manual transmission, 126,000 miles.
My back-up lights have quit. Checked both bulbs and
fuse using a multimeter. Removed switch to replace with an after market unit. When comparing the old switch with the new I noted the threads on the new unit were twice as long as the old. I also checked the old switch operation with a meter and it was functioning correctly. I did not install the new part for fear that the longer threaded area could damage the gear box. I returned the new switch to the seller and he was of no help finding another model.
Can you help?
Thanks,
Tom
