round headlight conversion write-up

Postby jeremy_worden » Thu May 20, 2010 8:12 pm

like the title says this is a wright up that i have done for the folks who are looking at doing this.

first off you need the grill, side lamps, headlights, headlight brackets, as well as the wiring connections off of the head lights, screws.

Image
Image
Image
Image
Image
Image

next is the tear down.

you tear down the old grill assembly
once you have that all taken apart set it all aside, dont throw any thing away.

Image

from there you do the main light, cut the connection about 3" from the plastic
Image
then you take the connections that you salvaged with the grill and splice them together, the color codes are the same.
Image
black is ground, red/W yellow stripe, and red.
Image
repeat for both sides.
next the side light is what was the hardest one.

first you have to cut the wire connections off of the lights that are on the marker lights you are replacing,
Image
then you need to cut the end off of the new (old) marker light.
Image
then on the marker light thats going in, you should have 4 wires 2 green/red, 1 black, 1 green/blue.
splice both the red/green. then the black is ground and the green/blue is the blinker.
Image

then you add the connector off of the first light.
you need to take the green/red and splice to the green/red, green/blue to the green/black, and the black to black
Image
repeat for both sides.

then you can start the install. brackets then the lights.
Image
the grill should snap into place, behind then marker lights you should have two screw holes that should let you mount to the back side.
Image
once you have it all back together it should look like this
Image
unless you have a grill guard then this is what it should look like.
Image

if i forgot anything please feel free to comment, this is my first wright up.

Looks good. Now I need to go look at mind and see if it has those out screw holes. I'm sure it does and I just missed it. I like the brush gaurd too. Looks cool. I saw one once at Pick & Pull but it was smashed on one side. :(

Very nice write up. I just want to emphasize that the donor vehicle grille attaches differently than the 87 up grille. The 87 up grille attaches to the body with a series of clips. The 86 down grille uses screws which go through the grille into clips which are attached to the body.

The white clips on the top/front grille area, behind the yellow lens, and beneath the grille all need to be salvaged from the donor vehicle along with their associated screws.

I can't recall; aren't the ones behind the yellow lenses larger than the others?

Thanks. Especially for taking so much detail in the wiring part. You confirmed what I thought I was supposed to do.

Very nice write-up.

I would like to add one little thing. I reccommend using shrink tube or other means to make those butt-splice connectors weather-tight. It might save you from chasing an open circuit after a couple of winters.
Butt-splices are pure evil in my neck of the woods (salted winter roads). I try to get the uninsulated kind then cover them with heat-shrink tube. :)

So I guess this means I could also convert my 86 to square headlights if I can't find a round headlight grill to relapce my broken one. 8)
Or would that be blasphemy? :shock:

A great write-up!

My question is what is the main purpose/attraction from converting from square to round?

Is it looks alone? Or something more practical, like cheaper bulb or assembly replacement?

I know I need to replace the drivers side headlight assembly on my 91 troop because, at some point, the bulb was not properly replaced and the inside of the glass refuses to come clean now :evil:

the reasoning for me was the retro look of the 86 trooper. i am planing on getting a bulb conversion to a halogen bulb for better light, but mostly for the looks.

They screw to the body. The holes are already there and should line right up. When you pulled the buckets, did you pull the bolts as well?
