Looking for some info on what I think is a diode. Its in the wire bundle at steering column. Orange plastic is melted. Has 3 wires red red white.
on tvp there's a partial thread where wonder wagon references kcg795 and says that this is a diode.

My girlfriend just bought an 89 van 2wd. Headlights don't work. P.o. bypassed with wires to lights into cab and a hot wire to make them operate at night, and unhook when done driving.
starting my trouble shoot, and found this melted orange diode. Three wires.

I did a search for orange, headlight, diode and got no matches. Has this been discussed before? Anyone have info on the wires to this diode? Maybe I can bypass if nla from toyota
