My 88 isn't relayed - a lot of people confuse the pink dim/dip relay as a traditional power relay - which it is not. It merely activates the full headlights if sidelights are selected and the ignition is on.
If you are upgrading to halogen headlights then seriously consider a relay powered loom for the following reasons:
1. It gives much brighter lighting as the system receives full 12v power.
2. Halogen upgrades are often 55w compared to 35w of the sealed units, thus draw more current and eventually melt the rocker switch.
3. It eliminates issues related to old wiring and inherited poor connections
This isn't a plug - but I make a full harness including sidelight wiring and independently fused lights for £60 if you didn't want the hassle / worry of doing it yourself.
