I also bought mine at Amazon. This might be the same one.

Conversion harness, or factory harness? I can see this happening to the factory plugs, which is why you need to do the conversion with the ceramic plugs.Just wanted to add a thought to the H4 Hella High Wattage bulbs. I've seen where these types of high wattage bulbs draw more current that is safe for the harness/plug. After a few months of usage in a friends 88 PU, it melted the plug housing on the back of the bulb. JAT
It was the factory harness. Heavier gauge and ceramic plug would be the way to go, for sure.Conversion harness, or factory harness? I can see this happening to the factory plugs, which is why you need to do the conversion with the ceramic plugs.
Do LED's cause issues with the high beam indicator light? Because I have LED's (for now, came with it) and have no indicator even after cluster bulb replacement.UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE
You guys are 100% on the money. The LED WILL NOT WORK on a 1987 Toyota without special wiring provisions.
Now the rest of the story:
My truck has just got back up on it's feet after an extensive mechanical refresh (new motor, trans, clutch, rear axle etc. etc.) and for this reason I have not been driving it at night, or even on a regular basis. I have struggled getting parts like the discontinued Cold Start Temperature Sensor, which I come to find you can only buy used. When the parts finally straggled in I started driving the truck at night, as my confidence grew.
Then I noticed it - sometimes it seemed like my headlights were not even on! Jiggle the switch and then they pop back on again. Then I saw that the high beam indicator light was lighting up on low beam position. What gives? I thought back the the conversation above this post and realized that the LEDs were causing the confusion. A quick switch out of H4 lamps confirmed my suspicion.
You guys are 100% right and demonstrate the power of the Ih8mud forum. Thanks a hundred times over!!!

Ya know, I thought it was my dash. I have a high beam light, but it's dim. I have the conversion harness for H4 headlamps.So I currently have HID’s from DDM tuning. Pretty bright, not too many issues over the years. Kit includes an entire harness with ballasts and relays. Only issue is I’ve never had a high beam indicator light. Can I use this adapter thing in conjunction with my current setup? Thanks!
You're over analyzing this. Unplug headlights. Take headlight plug and plug into new harness. As I recall you only use one. The two ceramic plugs go onto the headlights. The red wire goes directly to the battery. Black wire to the ground location of choice.So I am doing the H4 conversion this weekend. Bought the light assy’s from LCE and I just recieved the harness that was referenced in the link above. It appears to be a straight forward install, except I dont see where the replacement harness plugs into the truck. Does it go in the fuse box?
that is the only place I see male connections that are similar to the ones a the new harness. I looked in the fsm and the correctly colored wires are present in the fuse box
