Default Need Help With Custom Headlamp Install

I have a 91 FXSTS. I want to replace the stock headlamp with one that I purchased here: http://www.skullmanonline.com/sk-1337.php

However, no instructions, wiring diagrams, or anything came with the headlamp. I've asked a few of my friends about it but they're not mechanically inclined enough to put it on for me or tell me how to do it.

It has: Halogen 100 Watt high beams shine thru the eyes, and halogen 50 Watt low beam which shines thru the mouth. Fully adjustable and replaceable bulbs..

Okay, so out of the skull there are 6 wires: 1 short black one, 1 short white one, 2 long white ones, and 2 long white w/black ones. (see pics)








Can anyone tell me how to install this? As an aside, this things weighs about 8 lbs. I don't know how much that matters....

Oh, I suppose I should say that I understand the disbursement of lead wires:
The two short wires (1-black, 1-white) are the positive and negative lead wires for the high beam. The 4 long wires (2 white, 2 white/black) are the positive & negative lead wires for the low beams. I get that.
But my question is, how do I wire them into the connector block? Do I need a new or modified wiring harness? Ugh. I hate working with electricity!

First of all welcome to the forum, I hate wiring too!
can you see what wires come from the low beam and high beam
I bet the short wire is the ground for the headlight

You need to figure out how your headlight is wired up in your bucket and use a multimeter and determine what wires are what on your stock headlight, you might have to call the company you bought the headlight from and ask them how to wire their headlight, just a thought

Custom Headlight = Custom wiring. Simple math. You will need to test the pin outs or get the manual and find what needs to supply voltage to each set or wiring. Attach accordingly.

You should email the company you bought it from for the most accurate results.

The first thing I did was to contact the seller (www.skullmanonline.com) and ask about wiring it. They flat out refused to provide any (verbal) information or diagrams. They even have a disclaimer on their website about "not being held responsible...blah, blah, blah."
I am more than a little annoyed since I paid $500 for this thing.

Be that as it may, I have finally figured it out!

1) There are 2 - 50 watt bulbs for eyes (Hi-Beam). From each eye comes a long white wire and a long white wire with black marker. The white wire is hot. The white/black wire is ground. Twist together the white wire from each eye and attach to the white wire on your 1991 FXSTS.
2) Twist together the 2 white/black wires and ground to the frame.
3) The short white wire is for the low beam - attach this wire to the yellow wire on your 1991 FXSTS.
4) The short white/black wire is to be grounded by attaching to the frame.

Voila! A super-hott chrome skull headlamp!!

I'll attach pics soon
