I'm installing the Slee head light and aux. light harness. I need to know how/where those who have done this mounted the relays. I'm a bit of a perfectioinist and can't just mount them anywhere. In fact, I've routed the harness so it's as inconspicuous as possible. (You should see how I installed my sound & heat instulation.)

Any pictures or ideas for a clean install are appreciated.

BTW: I DID SEARCH!
 
Mounted them to the back of the battery box. Not sure if that qualifies as "perfectionist", but it's been working for almost a year!

Hey, just looking for ideas. I like this one. Might work for me.

I know I've seen pictures somewhere of the relays mounted on the fender, but I can't remember where, and exactly what, it looks like.
 
I mounted the relays on the inner fenderwell just next to the battery. There are two threaded holes already there and you just need to find the appropriate size fastener. I mounted one by itself and then two are mounted on the bracket Slee provides and then mounted to the fenderwell.

I agree about the wire routing, it is a mess and difficult to make it look clean. I just put in a new battery last weekend and cleaned up the wires as much as possible - basically I just wire tied the mess together and tucked it up by the headlights.

Let me know if you want pictures.
 
I put mine on the fender inside the battery box using 2 factory holes (probably the same spot as TomH). The picture was taking leaning over the driver fender looking down at the battery/fender. I'm sure you can make it look cleaner than I did too.

Here's a pic... Looking forward from behind the driver's side battery box.

I ended up going this route. Doesn't look too bad. But after seeing the battery box picture, I wish I'd gone that route. Anyway, they're (kind of) out of sight.

The wiring on the drivers side didn't come out as clean as the passanger side. More 'stuff' to arrange and tie up. It's done though, and I'm satified.

Thanks for the help!

can you guys tell me how much of a noticable differance it is with the harness?
 
I put my relay in the same spot as Toy350-a great spot. All the wires are zap strapped and laying down in front of the battery. Its not that neat but it works. I can not tell a difference from factory...

I would say there is a definate difference.

However one small caveat to the above statement I also installed new high intensity lights from Daniel Stern at the same time so my truck sorta received a double whammy so to speak.

I am in the same boat, I upgraded to HIR's at the same time as doing the harness.

I just turned them on without the truck running and they were brighter. The cruiser won't start now though???:confused:

I went this route as well, relays on the inner fender well. I ended up installing the harness twice to get the wires the way I wanted it :rolleyes:. I wish I had done this mod sooner.

I installed a set of Sylvania Silverstar Ultras at the same time. :idea:
I plan to replace the battery cables soon.
 
Without looking at the wiring diagram, isn't the circuit already protected by the factory headlamp fuse? Doesn't this harness just plugs in to bypass part of the factory harness?

Cheers, Hugh

The factory headlight circuit is what powers the relay. The relay would have to be having serious problems to trip that fuse. The power for the headlights now comes directly from the positive terminal of the battery and is merely switched by the relay, not fused.
 
Does it bother anyone else that there is no fuse on this harness? It was really bothering me so I redid some things to add fuses and incorporate the relays into a fuse/relay panel.

There are fusible links where the harness attaches to the battery.

P.S. Just installed mine. Mounted on inside of fender, as above. Hi-beams seem bigger and brighter, not sure about low-beams.

Hmm, maybe I'm missing something, but I don't believe mine have them. Then again I was a bit surprised that slee would make something with such a gross oversight, so I probably am missing something.

Mine has them (fusible links).

Ary,
I have the "old style" Slee harness before they came with the fusible links. No fuse bothered me so I added an in-line fuse behind the battery box. Several other things about the old harness bothered me too.... like it is about 10' too long and I was in a hurry and didn't cut and splice the wires so all that yellow harness is wadded behind a headlight. Still bugs me... but not enough to rip it out and do it again. :D
