Have been working to replace some lightbulbs on the interior of my '94 FZJ80 over the past few weeks and i thought i'd share what i found.
Antenna up/down buttons use this bulb:
www.mouser.com
Other large buttons on dash (ECT, center diff lock, defroster) use this bulb:
www.mouser.com
Also, after some searching, i found that the shifter should in fact be lit. By removing the shifter trim and looking under the shifter, i found a green wire leads to a Type 74 bulb with a green cover. The green cover can easily be slipped off the old bulb and onto the new. To access the light, 1st, shift into neutral. Then remove the 4 screws (2 on driver side, 2 on passenger side) that hold down the trim. Screw off the top of the transfercase shifter. When lifting the trim, rotate 90 degrees to allow the shifter to slide out of the trim.
Bulb here:
Amazon product ASIN B00318V1BU
Hope this helps someone refreshing lights in the future!
