Ok I have the lights installed working and they look great. They are Hella 500's. I wish I had asked this before I drilled the dash for the switch though.

They are wired with the provided relay and switch directly to the battery. Yes they are fused. What I would like to do though is have them go on and off with the high beam switch and I would also like them to time out like the auto lamps do. My thought was to tap the high beam circuit to power the manual switch. That way when high beams come on the switch is powered and the lights come on. When the auto lamps go out these lights go out. Does this make sense? I think so, tell me if i am wrong.

So the question is where do I tap the high beam circuit to power the switch. What color is the wire.....? The truck is a 06 F150 Super Crew in Lariat trim.

Thanks,

 

Easy place to get the high beam circuit in the cab of the truck is after the MFS in the steering wheel column.

The wire that feeds the coil on the high beam relay is a yellow wire in the column, pin # 9 on the MFS.
This is what you would have to the switch, then the switch to the relay coil under the hood.

Don't know how important the switch part of the equation is, but you can just tie the aux lamps relay coil to the high beam circuit under the hood, light green w/ black stripe wire on the bulb connector. Just an option, but would not have a switch included with it. This is how the Hella lamps are wired in my Hella grille, always on with the high beams only.

 

As usual, SSCULLY's right on the money, but let me see if I can add something. Where you tap into the hot lead to your high beams can be just about anywhere along that circuit. I have me Hella 550's wired so that they come on automatically with my high beams. The relay is triggered off that same circuit. Since my relay is located under the hood near the battery, I tapped in right next to the headlight on the passenger side. The upside? Everything is fairly easy to reach where as under the dash or in the steering column is pretty cramped. The downside? The environment isn't as well protected as it is in your cab.

 

Well after using them for a few nights I really wish I had not drilled the dash for the switch. That is the exact setup I would have rather had. Well now I have a switch for another toy pre drilled and installed. I will most likley go with the no switch setup in the very near future. As far as the elements are concerned. That is why we use solder and shrink tubing. Thanks for all the help.

 

2stroked does make a valid point. If you mount the relay up by the firewall behind the battery, there is more then enough protection there. This is where HElla says to mount both relays for the lamps in the Grille.

I have a relay on my '02 ZG-1000 for 6 years now, with less protection, problem free.


This is behind a side cover, mounted to the rear fender. I ride this bike year round, it is not a trailer queen

 

I've actually got it right beside the battery, but SSCULLY's suggestion is even more protected. I've used this location on the last 3 trucks with zero problems.

 

You guys are killing me. Much better ideas than I had. I have the relay on the trim above the firewall. I will be cleaning it up in the near future.

 

2stroked, that is the same place I had my MAXI fuses for my E-Fans on my 2001. I don't think they ever got dirty there either.

 

Well it took me 10 months to get it done but it was quite easy. I left everything in place and just tapped the high beam for signal to the relay. Cleaned up my original install while I was at it. No more dead batteries from my wife leaving them on. Thanks again for all the input.
