Topic: Wiring tag light

[melbill]

I have searched, checked my Haynes manual, and looked at the Factory Service Manual here with no luck.  I flush mounted my tail lights and need to wire up new tag lights.  I am using lighted bolts on the top of the tag.  The wires  come out the back and I have them soldered and shrink wrapped.  I am planning to run then through some wire loom through a grommet through then plastic piece that holds the filler neck in place, then connect the wires to the wires for the rear lights. 
Does anyone know which wires I should tie into; both with the pos and the neg wires?  Also should I tie in on the light side or the vehicle side of the plug?  I have 3 wires on the vehicle side and 4 on the light side.  Lastly, should I solder and shrink wrap the connections or is there a better way to connect these wires?   

Thanks for any help,
Bill

"...
Reverse = white/black
turn/stop = white
park = light green/black
..."

So, one wire goes to the ground (the body) and the other goes to the parking light (or otherwise called the running lights).

I would just use butt connectors with shrink wrap over it.  Eletctrical tape works too, I just don't like the goo if I ever have to monkey with them.

this is from the '95 FSM wiring diagrams page 114 (8w-51-4 in 95yj_8w.pdf file), i can't remember what year of vehicle you have so the colors could be different: on your stock tail-lights the vehicle should have 4 wires
ground - black
tail light - black with yellow stripe
brake/signal - dark green with red stripe for left side, brown with red stripe for right side
back-up light - violet with a black stripe

you should connect the tag light to the tail light wire which is the one that is hot when you turn your lights on - black with yellow stripe in this case
the other wire should be connected to ground - look if the tag lights have a ground wire connected there so make sure you don't connect them backwards as it could give ground thru the mounting screws as well and you could blow a fuse

i would use a weatherpack or metripack 1 pin or 2 pin connector depending how many wires you have on your tag light to hook into the harness, that way you can disconnect the tag light and remove it no problem - NAPA or such store should have those. If your grommet is small i would consider using 2 singles (2 x 1 pin connectors) to make sure it can pass thru the grommet.

Best is like you said to solder and use shrink tubing, but i would suggest using a bit of RTV on the wires and soldering before sliding over the tube and heating it to shrink, since you would have 2 wires side by side one could pull the tube apart and let water and dirt in there.

hope this heps

EDIT: 1995YJ beat me to it but he's got different colors so see which one matches, i didn't check on the vehicle and my info was from the FSM

Thanks to both of you. I looked at the '94 FSM, but I couldn't find the wiring descriptions.  This should make it much easier.

Thanks again

I'd go with sharpxmen's colors.  Mine were only googled.
