spot lamps/side light

[anthony whatford]

hi, I am about to wire a set of wipac lamps on my 3rd gen hilux. I previously had a hilux 4 cab & fitted a pair of cibe's all wired correctley with relay & switch, the relay taking its feed from main beam. All worked well apart from the cibe would work when I had side lights on! Weird! I checked the voltage and there was a current going to relay from main beam circuit
Is this because of the negative switching?
I am about to wire the wipacs in so any help would be much apreciated
cheers

I have spots wired with the feed to the relay switch from the main beam. This works correctly so you should have no problems. Best thing to do is get a test lamp on the connections to the headlamp bulbs and find which one only comes on with the main beam, that way you are sure.
I think that the previous Hilux probably had a bad earth and was leaking back along another earth path from the sidelamps thus causing the problems.

The Surfs do use negative switching. If you wire the relay up how it tells you to on the packaging the lights will go off with main beam and come on at all sorts of funny times. You have to take a 12V feed to the coil of the relay and the take the -ve side of the coil to the main beam wire on the headlamp.

thanks I thought something was amiss before, don't suppose you have a wiring diagram of the relay?

If you use the feed wire to the headlamp bulb rather than one from the fuse box for the relay coil, you get a positive feed so you can use wire as per the instructions. It then wires exactly the same as any other car as you are positive switching it.

Because of the way the headlights are wired the circuit reads (from top to bottom):- 12V, fuse, headlamp, dip switch, ground. Therefore, if you wire it up as normal the spots will be on all the time (at least they were when I wired mine in - who reads the manual anyway!).

To wire the relay correctly you need to take a 12V feed to terminal 85 - you can piggyback off terminal 30. Then take terminal 86 to a scotchlock on the R/Y wire on the back of a headlamp.

Yep that's the way I wired mine, couldn't remember the color code though, just took out a headlight bulb, used a test lamp to find which was the live feed to the main beam and scotchlocked to that.

When I fitted mine I found that the live feed supplies both the main and dipped beams and the other two terminals are both used to ground the filament that is reqiured.
All I had to do was find out which one was to ground when the main beam was lit and then I connected the relay to the common live and the wire that was grounded for the main beam.
Clear as mud -- BUT THEY WORK.
