Does anyone have suggestions for the relays. they seem to be hard up here to find.Or where to purchase them in the USA. Thanks in advance. Ron
How many do you need?? I'll bring them in May. Lots of them at work. I do all kinds of wiring work arounds with relays so I always have a bunch on hand.
There is a good diagram on the Ford Trucks site http://www.ford-trucks.com/article/idx/8/208/article/Headlight_Relay_System.html
that's the way Earl and I wired ours...the old plug is used for the...trigger ...for the relays... ......
I need to do this....I have to drive around all the time with my high beams on because I cant see anything with low beams, the HLs are straight and aligned and everything, and still cant see anything. I can barely see any better with high beams...lol You might as well write a picture book for me going step by step, all these technical terms are just jibberish to me...lol
This is a very easy modification to understand. First thing, as always when working on the electrical system, is to disconnect the battery. The dimmer switch has 4 wires, one coming from the light switch feeding power to the dimmer switch, and one going to the headlights (Low beam). The other is the High beam, it will have the wire going to the high beam indicator made on the same connection. Two of these wires goes through the firewall to the headlights (low beam & high beam) Using a relay for each wire. Connect the wire going to the headlights to the #86 terminal to trigger the the relay. Run a 12V wire to terminal #30. Connect the wire going to the headlight bulb to terminal #87. Connect a ground wire to terminal #85. Now you have one set of beams working. Do the same thing with other wire coming from the firewall.
that diagram helps the understanding of what you have to do a lot for us electronically challenged people
Dont forget that Batt. supply has to be fused. I use in line holders. Shows fuse link in the diagram.
Ok thats a LOT more understandable...the only pic I saw was one that was drawn in Paint...Im pretty good with electrical stuff but relays completely throws me off, never bothered to learn exactly what makes them work. I'll definitely be doing this.
I changed the image to the diagram that I drew when I did this modification. The main difference between this one and the other is the other one used a fusible link and this one uses a breaker. If the breaker get too hot it will reset when it cools off...if the fusible link gets too hot it will melt and you have to replace it. The reason your headlights will be brighter using a relay is because the electricity doesn't have to go from the starter solenoid, across the radiator support, the length of the fender, through the firewall, to the light switch, to the dimmer switch, back through the firewall, down the length of the fender, across the radiator support, to the headlights. The 12 volts that started this scenic route in now down to around 9 - 9.5 volts by the time it got back to the headlights. With relays the electricity only has to cross the length of the radiator support before it gets from point A to point B.
