110 mystery component

[C18RCH]

Hi,

I have a 1988 110. I've had some electrical problems so decide to re-wire it. I've dismantled the dash board and discovered a component I don't recognise (see pics attached).

It is located behind the dasboard instument cluster and has a connector wired into the loom but was not connected when I dismantled the dash. If I connect it, it turns the lights on regardless of whether they should be on or not. The lights are working fine (one of the few things that are) without it connected, but what is it?

I assume it is some sort of relay, but I've never seen anything like it, and since the lights work without it, what is its purpose?

Cheers,

Rich

Its something to do with old MOT requirements to do with headlight dim /dip which have now changed beyond that my memory fails me.

Someone will be along shorty to tell you exactly.

hi there.two part nos prc8123 control unit dim-dip/quartz halogen

prc 6336 control unit dim-dip sealed beam.well thats what it looks like in the parts book hope this helps

that mystery part is the older dim dip transformer, for UK dim dip headlight requirements was quietly dropped form the vehicle lighting regs a few years ago, if you just unplug it & secure the plug safly out of harms way, you can drive & just have normal road lights without dimdip.

I drove my next door neighbour's 10 plate 90 for the first time on Saturday, and that seems to be fitted with dim dip, so presumably it's making a come back as one type of DRL.

Cheers Gents.

Thats something else that can be pulled out then. I'm going for kill or cure at the moment. Any wiring that isn't doing anything is coming out!
