Questions: My 1948 CJ-2A has this style brake switch with the male ends. Will this fit in a CJ-2A or only MB's and GPW's?
Question By: Ryan on May 29 2017 4:25 PM
That is more MB/GPW style typically. The 48 CJ-2A would have female ends.

Questions: Is there a female end that clips on to the switch pins? The detents make it look like something slips over the pins to make the connection to the wires. My CJ-2a had no wiring to the brake light switch when I got it, so I want to wire it correctly.
Question By: Zach L. on Jan 2 2017 5:14 PM
The male connector is a NAPA item and can be heat sleeved in. We also offer complete wiring harnesses too.

Questions: I just pulled my (looks to be an original sigle stage) brake master cylinder out of my 45 MB will the old brake light switch fit the new dual master I have purchased (waiting for delievery) and if so how do I bend test the switch. I have it out but a multimeter on it push a small flat stick into the hole on the other end push in but no meter change pooks like a bad switch to (brake lights did not work prior to pulling master)

You will need to reuse your old outlet bolt part number: 637605 Also check out our diagram section on brakes/master cylinder for your vehicle and it will help too. Its just a pressure switch.
