80 series Wiring up Driving Lights

[plumber]

Hey,
Tried wiring up my IPF's to my 80 the other night, i have since discovered they are a negative switched system, so where u would normally splice your wire into your high beam contact, it gives dim, dull light, and when spliced into the high beam light itself, is not legal, as it does not switch off when you dip your high beams,

Where do i splice in the high beam wire? i have attempted both connections on the right hand side of the vehicle, do i try the left?

If someone out there could tell me how the stupid japs wire these jiggers, it would be appreciated, thanx

yes they are negative switched. which means the common always has a positive 12V supply to it.

if you run a wire from the inner, drivers side light (should be 2 wires there) to the relay. put a switch in one of them (doesnt matter). it should work.

I have a pitcure drawn up but i cant post it.

Use the -ve wire at the high beam as the negative side of a relay coil, and use a switch in the cabin as the +ve side.

That way they can only go on if you have high beam on (gives the relay -ve) AND the switch on (gives the relay +ve).

thanx guys, i will cut into the negative wire on the high beam lamp, and see what happens, cheers

this is prob best way (ie easiest) to do it. if you put relay in engine bay as well you can use lot smaller wire to cab and smaller switch too

As a rule of thumb i always use the 2 OUTER wires to run to the relay and via a switch.This way it doesnt matter if it is Positive switched or Negative switched.
You just run 1 wire from the plug thru a switch then back to 85 on the relay,the other wire runs to 86 on the relay.
Cant go wrong like this.
